Games will play for a few seconds then will go to a black screen.

I have replaced the fuse and all the capacitors on the board and games will start for a few seconds and then go to a black screen, but the audio will continue like normal. Does anyone know what would be causing this problem?

Have you tried cleaning the pins of the cartridges?

@doctorkennyg Yeah. I've also cleaned the slot in the console and I've used different cartridges.
