I've always had this random power adapter that I always used with my Famicom with no problems. I did some rearranging today, and when I turned on my Famicom nothing happened. After trying a bunch of things, I decided to check the voltage on the power cord, and all of the sudden it was at like 15.5 volts dc. It had worked flawlessly for more than a year so this was really strange and unexpected. Admittedly, I had never actually checked the voltage before but it had worked fine so I never bothered checking. How can I prevent this from happening in the future, and is my Famicom completely fucked, or is there like a fuse or something that just needs to be replaced? Thanks /vr/.

There is a fuse near the power jack that you can check.

For what to do in the future, any PSU for a Model 1 Sega Genesis or Sega CD should work just fine and is safe to use for an original Famicom.

9V DC 800-1000mA Center Pin Negative. Learn it, live it, love it.

they weren't related to power so i didn't bother including it. Since the Famicom doesn't have a power LED I tried cleaning the cart slot, cleaning the cart, checking everything was plugged in etc.

OP 15 fucking volts ?! Im not sure if the Famicom has a voltage regulator but if there is one its fucked ... Linear voltage regulators lower the voltage by dissipating heat in the heat sink. If you run it out of speck it may just fry itself or it fry itself and every part that lies behind it. There is a good reason why you should care about the needed voltage.

Might want to check the power is plugged in as well

>>6032238
I'm sure that it does and that the part is rated to handle far more than 15V. Sounds like your speck of a brain might be out of spec.

fucking lol you done goofed anon, probably cooked your caps

i have never seen the schematic but probably just a fuse or a protection diode burnt. even if the voltage regulator burnt(does it have one?) it shouldnt be too hard to replace/mod it

Mkay, good luck witch your broken Famicom. Hopefully it's fucked up... Fucking 15V brainlet.

I don't have any broken famicoms. Cry harder brainlet.

it's not the Japanese power adapter anon, If you had any reading comprehension you could've figured that out from the OP.

Yeah that's not the problem. You can run JP PSUs for decades on 120.
