First problem is the corrupted graphics:
I've come across Fagin's video which is somewhat similar although the problem was missing pixels rather an all over gibberish corruption. He fixed it by swapping out the video ram.
The second problem is that the machine won't spin a CD. I'll hit run and the access light comes on and I can hear the laser trying to focus but no spinning, the message on the screen will then return back to 'press run' and 'set disc'. Checking the drive with no CD and holding down the lid sensor I can see the laser activating and the lens also moves up and down a bit. I'm guessing this might require a pot adjustment to get it to focus? or an entirely new drive?
And the third problem, which at this stage isn't worth mentioning, is that the hu card needs to be pulled out a little from the slot otherwise I get a purple or beige boot screen but seems to run when pulled out a little further. Not sure if I came across a fix for this but it's something that can wait.
I know the first port of call is to recap the machine so before I order a kit does anybody recommend I purchase any additional video ram or some other chips? Appreciate any help.
