My NES wasnt connecting to my tv, but I found out that when i applied a downwards pressure on the audio and video inputs on my nintendo, it ended up working (i’m sure its not the cables, as I have tested many kinds) I tried opening my nintendo, but there was no way of accessing the interior of the input/outputs since the video card is saudered on the top of one side and the mother board is saudered onto the other side. What is wrong? What should I do?
My advise would be to disassemble according to the instructions on here. Take the cover of that shields the RCA connection (TV out etc) and take a close look at all the solders as well as the resistor and the PCB. Anytime it works when you apply pressure would intake a microcrack in the solder points etc. It is hard to determine exactly what is going on, but you will have to start somewhere. Attached find the schematic for your console. Good Luck and let us know how you are progressing. Keep those consoles alive :-))
