My Classic II suddenly stopped working. I hadn't used it for about 2 months and now upon power on it chimes but gives me a screen with thin vertical lines.
It are not the caps: both analog and logic board are recapped. It's a logic board issue.
The board is very clean and upon examination under a magnifying glass I can't see bad spots.
So it chimes upon power on but that's it. It doesn't try to boot from it's FDD or HDD. All voltages are good as well.
I have changed the Roms with a set of known good one's but that doesn't help either.
Where can I start troubleshooting this issue ? I'm think possibly 1 or more broken address lines but between which IC's should I start testing and which lines ?
