H = Heinously, M = Massive, G = Gonad,
I've got an MV-1T with a seemingly unfixable calendar error. Sometimes it shows a stuck green screen, other times it shows a black screen with "calendar error". I've already checked for +5v on the D4990 (which is present), replaced the oscillator a couple of times, reflowed the ceramic caps and even the D4990, but I still can't get to crosshatch or a game. The chip is kind of corroded, is it possible it needs to be replaced?
