This Nintendo AV Famicom (HVC-101) arrived with a gray screen and a catastrophically oxidised cartridge slot. A good clean fixed the boot issue; a full recap and 7805 voltage regulator replacement took care of the rest.

The AV Famicom that arrived yesterday wasn't booting up games. It would come up with a gray screen. I went for the easy cause first. So, I cleaned the cartridge slot and it worked. It turned out to have a massive amount of oxidation. #Nintendo #NES #Famicom #Castleva #RETROGAMING

1/3 Opened up the AV Famicom for maintenance. It was somewhat dusty, not too bad but, enough for it to mix with the deoxit I had sprayed yesterday and make a mess. #Nintendo #Famicom #restoration #RETROGAMING

2/3 Recapped and cleaned the board, couldn't match all the caps in physical size from what I have lying around but there's no clearance issues. Also cleaned the inside of the shell and the board after the recap. Reflowed the pins of the power jack too.

3/3 Finished it off with some #Castlevania.
