/vr/ - Retro Games

well anons, i'll just leave this here:

i've done the following mods:
>nes 'stereo' mod
>snes new power jack mod (using RF out hole)
>gamecube modchip (forget name)
>dreamcast VGA mod
>genesis s-video mod
>game gear recap

i've also repaired many gb/gba/ds systems as well as various controllers/accys for consoles

so i'll check in periodically to see if anyone has any questions based on this shit above

What do for a non-working Sega Saturn. It turns on but no sound or image show up on the tv.

Anyone know how to fix a Sega Master System II?

>>1214427
Alcohol bath or recap it.

>>1214478
I'm not big on fixing consoles so I don't really understand what you mean.

>>1214442
Not if we don't know what's wrong.

>>1214490
Clean out the internals (the motherboards) with isopropyl alcohol.

Recapping means replacing all the capacitors on the boards; they don't have an infinite lifespan.

>>1214343
6 Months? 8 Threads?

Damn, I remember when you were asking if making this was a good idea, and I was desperately trying to get answers for trying to fix my Mega Drive.

Time flies.

>>1214513
It's just wonmt turn on, that's all I know.

>>1214442
>>1214513
>>1214554

Funnily enough, I have this problem as well.

I think the power may not be the right one for it, I have RF for it. But I have no idea if it's on or not. How would one check if nothing is being displayed on the screen?

>>1214558
For mine, there is something rattling around on the inside. So that might pose a problem.

>>1214565

Open it up, Sega's take normal screws.

You can probably find a guide somewhere.

Be careful though, I remember I cut myself good on a RF shield in a Mega Drive 1, so there may or may not be one in there.

>>1214554
That narrows it down to the power circuit.

1. Check the power adapter and make sure that works.

After that you need to open the console up:
2. Check the voltage regulator and make sure it's giving out 5 volts.
3. Check the voltage on both ends of the switch and make sure it reads 5V on either side

>>1214574
oops also check any fuses before the voltage regulator, I don't know if the SMS has any but that might also be your problem

>>1214554
>>1214574
Also make sure to see if the power supply is compatible (appropriate polarity, etc. if you're not using an official one) and actually working. I look at the ratings and test it with something that takes in similar values to the output

>>1214574
>make sure it reads 5V on either side
when the power switch is in the on position*

I've got an SNES from 1994 and it generally runs well. The only issue is that if it's bumped, even slightly nudged say, by a person's toe, the console will reset. Any idea what could cause this?

>>1214547
I know, right? It's been a lot of fun.

>>1214590
Bad contact somewhere. Power supply and reset button would be the first place to check.

>>1214590
It might be the slot. Try cleaning it with some 70 ahcolo and a medium hardness tooth brush

bumping

Okay, I have a strange problem with a copy Oracle of Seasons I just purchased. I get pic related at the file select screen, but I can't seem to start a new game or delete any of the existing files (or load one, either).

I have a feeling it has to do with the save battery, but I'm not at home where my gamebits live, so I can't really test it out.

Using my SP for illustrative purposes.

Pic of the underside of the cart.

There's some nasty black goo under there that's not in any of my other GBC carts.

>>1218473
after seeing that Im more surprised that it actually works

I'm thinking of creating some more teardowns for the wiki when I have some time. The wiki seems to cover at least a few non-retro consoles, so should I make guides for those too, or just focus on the retro ones?

>>1218660
Everything is welcome. What consoles were you thinking of making teardowns for?

>>1218473
What is that, mold? You gotta get in there and clean all that out.

>>1214590
If other suggestions do not work, it could be a loose power jack. I had the same thing happen to a Saturn. A good way to test is lightly tapping key areas. If tapping the cart causes a reset, it's a contact problem. If tapping the power connector causes it, it's the power jack.

>>1218673
I was going to start with the NES and Mega Drive II, but I also have an original Xbox and Slim PS2 I was thinking of doing

>>1218673
I could do a teardown of my FDS. I need to get it fixed because it won't read disks, but that doesn't matter.

>>1218470
>>1218473
>I can't seem to start a new game or delete any of the existing files (or load one, either).
>have a feeling it has to do with the save battery
>There's some nasty black goo under there
It's more likely that the SRAM doesn't work. This could be caused by corroded pins/connections of the MBC5, Reset-IC and/or the SRAM itself.
The PCB in your cart should look like in the right side of the pic.

>>1218687
What fucking dumbass soldered (badly) to the pins?
The only reason I do that is to test shit on an a cart for a shitty game.

>>1218692
*on a cart, fuck.

>>1218692
that dumbass:
http://www.insidegadgets.com/2011/03/19/gbcartread-arduino-based-gameboy-cart-reader-%E2%80%93-part-1-read-the-rom/

>>1218673
>What is that, mold? You gotta get in there and clean all that out.

I just did. It smelled like old Dr. Pepper (pic related). Still the same issue.

Can I take the save battery out and just dunk the whole thing in rubbing alcohol?

>>1218876
>Can I take the save battery out and just dunk the whole thing in rubbing alcohol?
You should be able to just make sure it dries out completely before you turn it on again. Preferably use a high concentration like 99% to minimize the amount of water in it.

>>1218876
Oh god

Get some alcohol and scrub it with a medium hardness tooth brush ASAP

>>1218884
>>1219669

Alright, scrubbed clean, given an alcohol bath and I let it dry. Still no change.

Is it possible to swap the ROM chip with, say, one of the Tony Hawk GBC games I see at my local /vr/ shop for $2?

I got a refund from the seller, so I'm curious to see if I can bring this little guy back to life.

>>1219913
If they use the same chips it should be possible. The solder joints are very small though so you will have to be careful

>>1219913
You shouldn't have submerged it

A scrubbing is all it needed

>>1219923
He wouldn't have done much if any damage, alcohol evaporates away quickly and the distilled water that is left isn't electrically conductive. It probably would have been better to scrub it down though in retrospect.

>>1219913
The dr pepper probably shorted out the SRAM chip, that's probably your only option aside from buying a whole new cartridge.

Just finished my first teardown http://retroconsoles.wikia.com/wiki/Sega_Genesis_II_Teardown
Let me know if I could improve it. I'll probably do some more complex systems when I have more time.

I just bought a master system II without the power supply, anyone know the spec of it?

>>1219913
I have thps2, but it doesn't have sram/battery saving.

but second one is worth buying for music alone, game itself isnt that good

>>1219935
>alcohol evaporates away quickly

Maybe 90% but 70% stays for a while. Just enough that it could do damage.

>>1219913
Do you have a small and fine solder iron or a decent hot air gun?
Then you should resolder/reflow all the pins, they might be damaged like in the pic.

>>1219923
>A scrubbing is all it needed

I did, and got most of the stuff off, but it still didn't work, so I decided it was bath time.

>>1220280

I was thinking of using pic related. It looks compatible, at least from the picture.

>>1220534
>small and fine solder iron

Not really, but the joints aren't THAT small. They look fine, but i might try this.

What would you recommend for cleaning golden contacts and boards?

Only stuff I have around is 90% Ethanol and old Lencoclean Supertonic which is just Isopropyl alcohol if I remember correctly.

>>1218470
Im sure its to do with the internal battery

>>1221185
A dead save battery doesn't affect gameplay. He should still be able to at least start a game.

>>1219913
You're getting some pretty bad advice so let me see if I can help.

The symptoms indicate a problem with the ram chip. The GBC supplies power to the SRAM making the battery irrelevant at the point you're having problems.

You absolutely did the right thing by submerging it. Submerge, soak, agitate several times. Goop tends to get stuck under the chips and and bridge circuits.

Make sure it is very dry before powering it up. I appreciate some kids are taught distilled water is not conductive. This is not true and any water on the board will quickly be contaminated by contaminated by contact with air making it very conductive. Compressed air is the best way to get rid of water. If you have a can or compressor great. If not use a straw. A hair dryer helps quickly dry up any bits you missed.

If it still doesn't work you can try to reflow the chip before replacing it. The easiest way to do this without special tools is to hold a high powered soldering iron just above the pins until the solder melts. It will turn from a matte silver color to a shiny silver color when it does.

If this doesn't solve the problem then it's time to replace the chip. That's the ram chip (W2465-70LL) not the ROM chip. Swapping the ROM with TH might best case scenerio give you a TH game in a Zelda cart. Depending on where you buy it it shouldn't cost more than a couple bucks. If you have a good electronics shop in your area you should be able to pick it up for less than $1. If you have any SMT experience you'll have the stuff you need to do this. If not, it's not the best first project but if you're up for it pick up some flux, paste, and braid and give it a go.

>>1221864
>You're getting some pretty bad advice

Everything you've said has been suggested already

I installed a backlight kit in my brick gameboy but something is pushing on the back of the screen making it have a dark spot.

Anyone know how i can relieve the pressure?

>>1222797
looks like you tore right through the polariser, you god damn retard.

>>1222817
That is a reflection, the spot is where the circle is, you can't really see it in the photo.

>>1222818
thats a reflection? jesus. well what are you using for the backlight? is it EL material? you have to account for the extra pressure applied by the foam behind the display, also make sure you aren't running any wires, have solder etc anywhere between the back cover and the screen, its similar to if you insert a shit chinese cart, as it warps the internals.

>>1222820
I took out the plastic screen guide since i thought that would put pressure on the screen, The tutorial i followed didnt say you had to though.

>>1219923
submerging is fine, just let it sit out to ensure it evaporates.

source: i work for an electronics company and clean boards all the time, hell we use to run some through the dishwasher...

My N64's power cable is fucked I think. It works perfectly fine, but every 5 minutes or so it resets itself. Haven't checked the reset button's contacts or anything but it doesn't appear to be stuck. All of my games work up until the reset. I did accidentally use gamecube cables at one point though, since they have the same jack. Could that have fried my console in a way that allows it to somewhat work?

>>1218473
I once got a Donkey Kong Country cart for the GBA that had the exact same kind of goo. I cleaned it and all, surprisingly isopropyl alcohol does the trick.

>mfw even when I cleaned it I never got the cart to work.

>>1223381
Does the power supply seem to be getting hot?

>>1223413
Nope, not even the slightest.

>>1223416
Have you tried taking the console itself apart and cleaning it out? The n64 gets somewhat hot under load.

>>1223427
Nope, haven't bothered. I will though in the next day or so, depending on when I can get my course work done before thanksgiving. I just always figured since there aren't any smokers or heavy shedding animals in our house that it'd stay pretty cool inside there. Does the N64 use any special screwdrivers like the GB carts do?

>>1223431
the six outside screws are 4.5mm gamebits the inside is just phillips head screws

>>1223434
>4.5mm gamebits
Eh, that's what I feared. Gonna have to order something for those I guess.

>>1223381
using a gc a/v cord wouldn't do anything, they're universal.

i know the n64's power adapter has built in resetting fuses if you fuck something up. leave it unplugged for like ten minutes before opening it up to check it out. i'd say the issue is the adapter not the n64 but that's just speculation.

>>1223452
I figured the a/v cord wasn't the issue, thanks for the imput. I'm most likely just going to order a new power adapter, it wouldn't shock me in the slightest if it's just that.

>>1223437
Good thing as it would be a shame to take the thing apart only to find that it is the power supply which can just be swapped out. Try it with a known good one too see if you even need to order that game bit.

>>1222870
>source: i work for an electronics company and clean boards all the time, hell we use to run some through the dishwasher...

Going to need some proof

And when people ask how you clean them do you guys really say you put them though a dish washer?

Most people assume water and electronics don't mix so telling them that shit is bad.

>>1223452
>n64's power adapter has built in resetting fuses if you fuck something up

Really? I've opened one before and I've noticed only a glass fuse

>>1224871
They probably say "We used a specialized cleaner for electronics."

>>1222680
Of course it has. The internet is a big place. I wanted to provide all that information here to save his from having to locate it in all the other places it has been suggested.
Also the bits that were suggested here were mixed in with BS so I wanted to make it clear to the guy who had the problem what was good advice and what was bad.
Sorry if you got butthurt because one of my points was already addressed by you or if you were one of the people offering bad advice.

>>1224892
I'm not butthurt but most of what was said was right. Only a little bit of it was BS

I plugged a dreamcast made for 110V input into a 220V power jack and didn't notice (because it worked normally during a versus match of SEGA sports tennis) until lots of black smoke came out. I opened the console and found some dark liquid inside. Now the console can be powered on but it auto-shuts down after a minute or so and can't be turned on back again immediately after it happens.

>>1224910
Its fucked

No really.

You most likely blew the fuse and every other thing on the internal power supply

>>1224910
You likely fucked up the power supply in some way, I wouldn't be surprised if the high voltage(~200V)cap(s) assploded. You might be able to salvage it depending on the damage

>>1224939
>>1224940
Thanks. Luckily I do have another dreamcast.
Is the power supply hard to replace?

>>1224990
Its one or two screws

Its the board on the left of the console

Keep the old board and see if you can't repair it

Also, why not use the other dream cast?

>>1224874
That's the extra protection, what anon said is true.

>>1214343
Hey. I'm sure it's one of the more common fixes, but I have a US SNES Jr. and the cart reader is failing. I've got to get the cartridges in at the perfect angle for it to work, and half the time it'll slip out of contact when I take my hand off anyway.

What are my options, and what video output mods would be worth doing while I have the console open?

Hey, I've been having a problem with my old Dreamcast. I don't use it very often and decided to buy a game I used to have as a kid and start it up again (Space Channel 5). This was a brand new game, straight out of the packaging, yet when I inserted it into the Dreamcast, it wouldn't recognize it as a game disc. However, I know my Dreamcast can play burned CD-Rs because Toy Commander works perfectly. Do you guys have any idea as to why an actual disc doesn't work yet a burned one does?

>>1224871
sure what kind of proof?

we don't run any boards through the dishwasher any longer, we had a communications monitor main board that would be fucking caked with flux paste,etc after the board house.

now we just use 99% ipa and fine brushes, soaking when necessary. we used to use this super corrosive shit, forget the chemical name. it was pretty wild soaking a fm transmitter board in this shit in a metal container, the metal would actually ice up.

>>1224890
oh, and yeah if it was ever brought up we just spat out sometihng that sounded good to the customer.

bonus points for whoever can figure out where i work!

>>1226760

It might be disc rot.

Or, a more likely cause, is that during the game's time stuck in the case it came loose from the spindle and got all scuffed up. Basically, check the disc.

>>1228248
Some pictures would be awesome with a time stamp.

I'm kinda interested in this now

>>1229205
I'll take some on Friday, we don't do the dishwasher thing any more but I can probably find a bom with instructions to

>>1226760
Your laser probably needs to be adjusted. If it's been tuned to run a certain type of CDR it's possible it will have trouble reading originals.
Tweak it a little (and by little I mean like 1-2 degrees) each way and see if either reads both. If not turn it until it will read the original, then get some decent CDRs and try those. Adjust until it reads both.
The most expensive CDRs are not necessarily the best. I've tried dozens of brands and two cheap Chinese ones, sohot and eblue, work the best for me.

>>1224910
By "powered on" do you mean it starts up fine and you can load and play a game for a minute or so or do you mean the light goes on or what?

>>1229304
Well, any pictures you want to share would be beneficial to /vr/

Got a game gear question

I picked up one on the cheap and the screen doesn't seem to work (lots of random patterns and no sound)

I know that the game gear is notorious for having bad capacitors but I'm wondering what ones I'd need to look at in specific for the screen and sound

>>1229518
Meant to post this too

>>1229518
Any particular reason you'd want to spend hours diagnosing which 1 cent parts should be replaced instead of replacing all of them in less than an hour for the cost of a stick of gum?

>>1214547
>tfw my suggestion for the name got shot down
eh, at least the name was picked.

>>1229886
Because they're surface mounted and they're not one cent each unless you buy a lot of them in bulk

>>1224871
actually, during the manufacturing process, the PCB's are put through water after the overn, to get rid of excess flux and other nasty chemicals. So long as there isn't a charge of some sort, it's fine to run boards through water

>>1229903
I though they used some sort of flux cleaner and not water

kinda neat, I guess

>>1229904

Disc rot. Early GD-ROM's are notorious for disc rot.

Hello,

Not so much that, as Sonic Adventure had a major issue with bad presses,

This might be the right thread for this, so how do you mod a Wii (update 4.3) so that it can play /vr/? I've used emulators before on my pc, but that's about all I really know about this sort of thing. I'm paranoid of softmod sites, could someone point me in the right direction?

Any info on doing game reproductions?

I've found desultory bits of information all over the web, but no comprehensive, step-by-step guide.

So I'm going to be getting a Famicom.

What's the best method of AV modding it?

There seems to be a lot of debate.

>>1231576
The methods are all practically the same, the only thing you need is a simple amplifier circuit on pin 21(composite video out) of the PPU. There are lots of debates about getting the "jailbars" out of the video but it's difficult to completely remove them due to the layout of the motherboard.

>>1231593
oh I also meant to post this, it gives you more thorough instructions.

http://jpx72.detailne.sk/modd_files/fc/avmod.htm

>>1231576
This is the one i used and i hardly get any jailbars.

But i use a AV famicom now.

What does the other symbols mean in that schematic?

Also, it doesn't say what to do with the video out cored after you have it installed

hey guys I was in the last thread where I posted that my SNES shit there bed.
I was told to open it up and remove the pin connector and clean under it and it would work again.
Sure enough it does once I cleaned it.
HOWEVER now I have a new issue. It works but the audio is a little fuzzy and staticy, I can still hear the music and the sounds the game would normally make, but with a little fuz and static.
Does anyone know why it's doing this?
Do I need a new 62 pin connector for it?

Got a PSX question

Why are some drives nosier then others?

I have 9000 and a 7000 model and the 9000 is infinitely quieter then the 7000

I took a laser off another 7000 and a drive from a 5500 to make a working 7000 drive. I've tried replacing the spindle motor, the drive actuator motor, and I've greased the fuck out of it but the disk still makes a "click" noise each rotation, like its not balanced even though it looks like it is.

I am wondering if anyone has any idea whats going on.

>>1233025
It would help to know what type of connection you're using. RF or RCA?

>>1233707
>>1233025
Also did you let the pins and the board air dry or blow them off with canned air? I've had some static caused by a small drop of alcohol not wanting to dry up

I have two issues. One. I bought a Playstation ONE with the portable screen at the Goodwill the other day and the Playstation plays fine, screen is like brand new too, still has that protective film on it. But problem is the backlight on the screen ain't working. The screen appears to display the PS menu and I can hear sound but just no light. Whats up?

Also I have a copy of NBA Jam: Tournament Edition that is having issues. It sometimes works when I power on the Genesis and sometimes I get black and blue verticle bars?

>>1233718
have you tuned up the brightness on the screen?

Also, clean the game

>>1233721
Yeah I've messed with the brightness and even hooked it up to a different PSone and to no avail.

Also yeah I guess that's a gimme.

>>1233728
I don't think opening the screen would be too hard to do if you're up to it

>>1233740
That was my next option, but I had been hoping there was something I was doing wrong.

>>1233746
On my quest to answer this >>1233705

I stumbled upon this thread http://www.assemblergames.com/forums/showthread.php?48112-PSOne-LCD-Screen-Power-Problem

Just though it might help even though your screen is turning on.

>>1233775
Thanks. I'll give it a try.

>>1233775
>>1233780
So after viewing the posts I am leaning towards a toasted fuse for the backlight. I will open it up and check for myself just to be sure. But this may have solved my issue.

>>1233808
Cool

Hope you get it fixed.

Now if I could only find out why my PSX drive is making so much noise compared to other models

>>1233810
That is very peculiar. I'll do some research on this and try to dig up some answers.

>>1233828
Yeah, I know. Thank you for any information you find

I might have an idea what it is but I'll test it later

There's a shield that you screw onto the under side of a 7000 and I think the 9000 model drive doesn't have it. It also only has two screw holes and has three peg like connections it fits on. I'm thinking its that third peg that's loose that's causing the noise

Its the the only thing I can think of at this point

>>1231110

Still nothing?

>>1234085
>>1231110
All I know is that you need a ROM burner to start

>>1233718
Could be a problem with the power supply to the backlight. First thing would be to check the voltage out of the transformer, if it's bad replace, if it's good consider dumping the stock backlight and using LEDs

>>1231608
>note: the 75 Ohm "resistor" is the TV in these schematics
Does anybody have the schematics of that amplifying circuit for the Frontloading NES if it's any different from the AV Famicom?

>>1237710
I believe the schematic for the av mod was modeled after the front loader's av circuit. AV famicom likely pretty similar

>>1220534
>>1220591

Okay, so I reflowed the SRAM chip, and holy shit, it worked!

A TON of brown shit came out from under the contacts; I'm guessing there was some more Dr. Pepper under that bitch.

Anyways, that's pretty neat. Free Oracle of Seasons.

>>1237710

I think I'm going to use the AV Fami circuit in mine.

Will a 220ohm resistor work in place of the 300? I'm being lazy and buying all of my parts at Radio Shack and they don't have 300s on hand.

>>1241307
nice work

>>1241317
If they have 220ohm they probably have the whole E6 series.

330ohm in parallel with 3.3kohm gets you 300ohm exactly.

Some people have suggested rubbing alcohol, but I can't seem to find it here- I think it might be more of an american thing. No pharmacies here have it anyway, and I've never seen it on sale.

What can I substitute instead of rubbing alcohol?

Would contact lens solution work instead?

No, as long as you have the correct AC adaptors and the Sega CD plugged into the system it should boot. One thing to keep in mind -- assuming that UK Mega Drives and US Genesis...es work the same -- is that the Sega CD requires the same AC adaptor used on the model 1 Genesis; the model 2 AC adaptor will not work. No clue how PAL units work, though.

>>1241764
The term for a functional (but not chemically identical) equivalent is surgical spirit. But don't use that.

Eyeglass-cleaning solution or, at worst, diluted Windex (window cleaning solution) can probably be used.

>>1241794
>eyeglass-cleaning solution

So contact lens solution would work?

Any danger of it fucking the laser?

>>1241781
Well, mega drive itself works, i can get it to start sonic (don't have any other games atm), but when i take sonic off and try to boot ground zero texas with mega cd i get black screen and cd won't spin.
If i push restart button in mega drive i get white screen, but still nothing happens.
I have took them apart 3 times now and hooked back together, but nothing.
It can't be because of bad tv wire, right? Because it barely works, but it still would need to read the disc and every time i have tried cd unit, i have gotten picture from sonic.

>>1241816
If the Mega CD is plugged into the Mega Drive with no cartridge or CD inserted the Mega CD should boot to the BIOS screen. Also the LED lights should flash on the CD unit. It's likely not getting power, but like I said, I have no clue what kind of power PAL units take. It may just be a case of not using the correct adaptor like NTSC units.

>>1241798
>contact lens solution
I'd think that stuff would be chemically different from eyeglass solution, but I really don't know about that.

Just don't go soaking anything or using an abrasive material like something fibrous or grainy, and make sure not to apply too much pressure. Canned air, for example, would be a no-no IMHO.

>>1241838
Wrong one indeed.
It's NES-PAL 002 AC adapter.
I guess they gave me wrong adapter in the shop.

>>1241764
I can't imagine civilized countries not having isopropyl alcohol in at least drug stores.

>>1242026
One pharmacy said they might have a bottle in the back somewhere, but that its really expensive (and probably a huge bottle).

I guess we just use more advanced shit to treat wounds

>>1242026
>>1242037
Like I said, other countries call it surgical spirit.

>more advanced shit to treat wounds
That's a retarded cop-out. As a basic antiseptic and common household cleaner, rubbing alcohol is cheap, chemically simple, and effective. I got a 16 fl.oz. bottle of the diluted stuff for a dollar just last week.

>>1242162
>other countries call it surgical spirit
fugg, self-correction:

Other countries call their similar equivalent surgical spirit.

>>1241307
Nice

Did you re-flow it with an iron or hot air gun?

>>1241838
I know that a Sega CD doesn't boot if you don't have the separate AC adapter connected to it

What Mega CD are you looking at? Model one or two?

>>1241816
So, i went today to shop where i bought my mega cd, and we tried it with working mega drive 1 ac adapter, we also tried some 3rd party adapter.
We still couldn't get any life to the unit so i tried to clean the contact points, nothing.
I'm going to open the unit and my question is what should i watch there for?
I know the fuse is atleast weak point in these, but is there other points i should check too?

>>1243754
Here
>>1243686
It's model 2, forgot to say.

I had a PSONE controller with a sticky X button so I took it apart and cleaned the button. I've done this many times with many controllers however the strangest thing happened. The D-ad and action button plungers were in place but once put back together I had to press those buttons like a mother fucker to get them to respond.

Even stranger I restarted the game and all of a sudden the controller was fine and I haven't had that issue again. What caused this?

>>1224871
Got an Atari Falcon running again by throwing the board in the dishwasher. Came out as new. Just don't put anything that holds a charge in it.

>>1243684

Just a regular $7 Radio Shack iron.

>>1243754
So, i opened the beast and here's picture of motherboard.

>>1243806
I also took picture from fuse only.

>>1243806

If they gave you an NES power brick, that WILL have fried something in your Sega CD, due to it outputting AC and the different polarity of the connector.

If you have a multimeter, my suggestion is to test the fuses, or just go back to the shop and tell them to give you a new one.

>>1243812
Well, getting new one is not possible (this was trade-in), but can it fry anything other than fuses?

>>1243809
None of those things are a fuse.

>>1243820
F301 isn't?
http://www.retrocorner.net/index.php?Mods_%2F_repairs:Mega_CD_2_fuse_replacement_-_page1 Says that F301 is the fuse, and the picture is from F301 (above D301)

>>1243809
It looks to me like the board has been wiped clean with some kind of wet wipes or diaper wipes.

If that's true that could be a bad thing (especially if they were scented or had lotion)

>>1243835
If it has been, they didn't do very good job.
Dunno what that stuff is, but there was this spot and little bit in other place.

>>1243812
Friend came over and we tried fuse, it didn't give any sign of life.
Does it matter if we use slow or fast fuse? Or should i just go with this guide? >>1243824

Hey guys, I've got an N64 that won't output any audio/video. I get some distorted flickering on my screen when I use an RF cable (but no sound), but my RCA cable just does nothing.

I assume I'm going to have to open it up and see what's wrong with it, but what are the chances a complete novice is going to be able to solve the problem with some solder and elbow grease? I don't really feel like going through the hassle/cost of buying the tools if it's something I'm going to have to bring to someone experienced to fix. I don't feel like breaking my n64 either, it's not something I randomly picked up at a flea market/garage sale, it's been with me for ages and has a bit of sentimental value.

I also realize it's probably hard to tell what needs to be done, without seeing pictures of the insides, but I'm hoping this is either somewhat of a common issue, or someone has experience in repairing this kind of problem with the console. Thanks in advance.

>>1243845
That stuff is some sort of glue to hold the wires of that mod chip down so they don't break off.

>>1243820
That green thing is the fuse

>>1244528
That isn't a mod chip. Some Sega CDs had errors in production and Sega dded in these "Fix" boards.

If the fuse isn't giving you a continuity test "AKA, a beep on a multimeter" it's dead and needs to be replaced

Guy with the resetting Dreamcast here again.

Cleaned the laser like you said, but I used surgical spirits instead of rubbing alcohol (should do the same thing).

First it just kept rebooting after the Dreamcast screen, so it cleaned it again.

Now it doesn't seem to restart, but it's not reading disks.

I got a screwdriver to open it up today, but its too small.

What the fuck is up with it? Did I knock the laser out of alignment or something?

>>1244743
You might have rubbed it too hard

You're suppose to just brush it with a q-tip

>>1244795
Yeah I did, I put a q-tip in surgical spirits, squeezed out the excess on a bowl, then rubbed it as lightly as possible, then dried it as lightly as possible with the other end.

I'm thinking of just taking it back to the shop- I got it from a retro shop where they seem to know their shit. I'll just bullshit and say I didn't touch it (to be fair, it was already causing problems)

>>1244809
Sounds like it has needs a pot adjustment for reading games.

Quick question

What type of flux do you guys recommend for electronic soldering?

I was thinking of getting a liquid flux pen

Also what type of solder wire or paste?

>>1245289
>What type of flux do you guys recommend for electronic soldering?
Rosin flux is what you should use for electronics. Acid flux is meant for plumbing

>Also what type of solder wire or paste?
You can generally use whatever as long as it's not acid core solder. 60/40 rosin core is what I use. Tin has a habit of making "whisker" like protrusions that can short out electronics over time so keep that in mind if you use a solder with a high concentration of tin.

>>1245319
Thanks. I already use rosin core solder. I just was wondering what flux pen is good

>>1245319
Oh and also lead free solder which has become somewhat common requires with a lot more heat to melt so you have to be careful not to burn up the PCB or components if you go down that route.

>>1245330
My equipment said to use only lead free but I said fuck it

The temperature gauge is off on it by about 100 or so F so I went with leaded.

>>1245330
>>1245334
>lead free solder
I never see the point to lead free solder. As long as you clean up your electronics and workspace when you're done and actually recycle electronics like you're supposed to and aren't stupid enough to lick things you're not supposed to.

This is not about repair but I have a question about console stacking.

I'm currently running short on space and have my Sega Dreamcast stacked on top of my (fat) PS2. Is there any problems associated with doing this? I know that one can overheat the other but both systems run pretty cool from what's I've experienced. I just ant to make sure one isn't going to affect the other somehow because I heard laying memory cards on top of a TV or VCR that is running can wipe or corrupt it. Again, this is all rumors but I'd rather be safe than sorry.

I also know both of those systems are not technically /vr/ material but I wouldn't trust /v/ as far as I can throw them.

>>1248252
Dreamcast is /vr/ now.
But I don't think stacking them should cause any issue. I've had an N64 stacked on top of a PS2 forever now with no problems to either. As long as they don't have their fan covered (Does the DC have a fan, even?) It should be fine. As for wiping of memory, that could have happened because of magnets? I'm not sure, to VCRs have magnets in them?
Regardless, It should be fine; like I said, I've had no issues stacking some of mine.

>>1248278
DC has a fan on the side.

>>1248252
There's no problem with stacking as long as the air vents aren't blocked on either one. A dreamcast isn't very heavy so it's not going to make the case cave in or anything.

Memory cards are pretty durable you can't really do much damage to them unless you take them out and zap the chips directly

>>1248278

Cool I didn't know Dreamcast was officially /vr/. Good to know.

There are vents on the left and right sides so that's why I figured it would be alright. I'm careful with the PS2 but usually the hottest part of that seems to be the bottom.

Thanks for the info.

>>1248281

Thanks for that and the extra info on memory cards.
I actually have another question. I heard stereo speakers have an effect on consoles if they are located close to them because of the magnets inside? I have a way old stereo system with really old speakers and they are about a foot away from the consoles. Is that going to harm them? We're talking big floor speakers with like 4 speakers built in.

>>1248293
Average consumer level magnets don't really affect much, cassette tapes and CRT monitors can be adversely affected by them but consoles use flash memory for pretty much everything.

Hard drives can be affected by extremely powerful magnets but speaker magnets are no where near strong enough to do any real damage.

>>1248307

Sounds great! Thank you for all the help.
