When I turn on the NES, it works fine, but after a few seconds artifacts appear (flashing pixels). Eventually, there are so many that the image is no longer viewable.

I searched for the amplified output of the audio signal with a scope a (.9-1V p2p max) and hooked up there. Here are the pics (my AudioSonic - Radofin is a latter revision than the one of the OP): https://postimg.cc/sMCPSr2K https://postimg.cc/yDrVtVSH https://postimg.cc/ZBz0sT1j https://postimg.cc/9rg05Pvv https://postimg.cc/V5LzfrBM https://postimg.cc/YLhc1Fbn Original: https://postimg.cc/jWXBmc1y https://postimg.cc/NKvV0ZqN https://postimg.cc/H8G02DtR Cartridge: https://postimg.cc/TLH2MfS6 https://postimg.cc/CRHFMjtC I trimmed it just for the right contract (checking with a scope the p2p again) and it works fine on both my Composite input monitors. I have 8 cartridges (the console was a present from my parents back in 1982) but it would be nice if we could dump them and put them on archive.org and make a multicartridge with all the games that were released. Hard project but maybe it's possible if everyone starts dumping them! The eprom seems a 2kx8 "D2616" (at least on 2K games) which shouldn't be an issue to dump.

This is repairable if you can solder .
