/vr/ - Retro Games

I have the RGB-02 revision of the Snes with the RGB-A chip in it and it's only outputting monochrome. It occasionally outputs slight purples too, but it's extremely faint.

Of course I checked multiple AV cables/TVs/games and can confirm its not any of those.

I've tried pulling the pin connector off, come to find out it was soldered in and I ended up having to resolder all 62 pins. I cleaned them first though. Reseated all the RF shielding too as I've heard that can sometimes be an issue.

Also, I attempted to adjust the color pot to no avail, and ended up ordering new NTSC crystals, which also didn't fix my issue after I soldered that in. Checked the board for bad traces too and cannot find even a spot of wear on the mask.

I ordered an OEM power supply, as I've been using a retrobit junk dual system one, and I'm hoping this ended up being a case of now enough power reaching the PPU.

If anyone has any suggestions at all, please let me know, as I'm stumped on this less replacing the PPU and RGB-A chip.
