Hey there, everyone! Long time reader, first time poster.. These forums have been a great help to me in bringing some dead Macs back from the brink. I've recently added a Color Classic to my collection. Of course it was completely dead when it entered my possession, but I've managed to coax it partially back to life. I've re-capped and thoroughly cleaned the logic board, and now she fires right up.
I'm having display issues, though. Of course. The screen is crazy bright. The contrast controls on the front work, and do a fine job of making the image look washed out. I can't reduce the brightness at all -- the brightness control panel refuses to work. I was going to pull the analog board tonight and give it a more thorough inspection, but I thought I'd reinstall System 7.1 from scratch in case it was a software issue. No dice. Now I'm leaving it sit for a day or two to discharge before I tinker with it again. Figured I'd pick some brains here in the meantime.
The analog board looks okay after a cursory inspection. No bulging caps that I can see. I imagine I'll replace them regardless eventually. Haven't checked for bad solder joints yet. I'll be doing that once I crack it open again. But at this point I'm not really sure what I should be looking for. Info on the CC is tricky to find.. Does this problem I'm having sound familiar to anyone?
Here's a pic of the screen I've got. You can see at the top of the display where the extra-bright raster is extra-noticeable above the menu bar. Thanks in advance for any advice!
