Another problem - image tuning via pot
Posted: Mon Jun 19, 2017 9:02 am
Hi all, so I've established the other issue (disappearing characters) needs a replacement Character Rom but can anyone help with this issue?
When I got the Vic, the image looked like this...
So I have adjusted the pot to improve image sharpness (only one pot as this is a PAL machine). The trouble is, I have turned it as far as it will go and it still doesn't quite get the image as sharp as it should be. Se below...
So my question is - is this pot trying to compensate for another chip that's just too far gone? If this Vic actually needs 2 replacement roms I'll probably just sell it on for spares.
