I replaced the cap with a known good different one with same Microfarads and voltage rating. Only thing is, this one said "SP" the other was a "SME" whatever that means. I dont know if theyre interchangeable or not, I just took it out of my Pitfall cart.

That didnt work. I took the ROM and cleaned the PCB with Brasso. No trace damage at all. It looked immaculate.

Cleaning the PCB did nothing though I did manage to get an all gray screen this time.

Im guessing the ROM is bad?

The only other component is a ceramic resistor but I dont think those go bad.
