Hello!
In the process of finding a way to reduce vertical stripes on Famicom touched on working
prefix with a capacitor 225 to the contacts of the capacitor of the 103rd C11 (next to U1 CXK5816SPS-15L).
Now Famicom does not turn on. Quartz changed, did not help. No image and sound.
When you click on the reset, a rumble is heard on the TV. PPU and CPU are warm when turned on.
I guess RAM burned out.
How can you determine what exactly burned out?
Thank

and it was working OK right? I did not understand where you actually put wrong this cap for jail-bars reducing and did you removed it after the fail ?  , you should put it between positive + from the PPU and closest ground - near bay . Also a video may be helpful  Smiley
try to remove all you work and back the console to the factory state , then just  touch the video center pin  RCI jack to  the video output from the ribbon cable, or directly to the pin 21 from the PPU to see do you have even week picture ,you have to be ground connected as well , you can just leave the RF gable in the console and the TV to serve like ground wire for the experiment
