| LC575 with black screen and faint read horizontal line at top!!! |
Posted by: beags on 2015-06-14 18:20:26
I have acquired an LC575 with a couple of problems that I know about at time of purchase but has since developed some more.
One was fuzzy graphics at thousands of colours - VRAM I think, does anyone know of a source of 512k VRAM simms?
Next one eclipses first one - Screen stays black and eventually gives a faint red horizontal line at top of screen. I have discharged the CRT and inspected the analogue board as I think that is where the problem lies, but I can't see anything obviously wrong and don't know where to go from here. Anyone know what component is faulty or has come across this particular problem and knows a fix?
