I am finding a lot of the faults are caused by them electrolytic capacitors being 10 years or over all need replacing.


All repairs i do i replace them in all consoles from 70s and up to the 90s consoles due to there being old now.
and some


If not all snes consoles i have had replace them when i inspect them boards if you see green crap on the legs replace them asap or the board will rust and all the traces will be gone for ever.
