AV famicom RGB mod black screen

Post by Barbe »

AV famicom troubeshooting after RGB mod

I installed Tim Worthington's RGB 4.0 mod on my AV Famicom.

At first led 7 flashed very fast but I managed to get image and sound.

A few minutes later I stopped having picture and sound so I changed all the capacitors and the voltage regulator.

Right now when I turn on the famicom the TV switches to the rgb channel but with no picture or sound. The mod board shows all the lights on solid (no led 7 blinking). The board gets extremely hot, you can barely touch it.

Any advice?

UPDATE: I reversed the mod and the console works OK, so the CPU and the PPU are not fried (yet)
