Damaged traces on IIvi - repairable?

Posted by: rawkinghorse on 2015-05-15 17:22:14 I posted this IIvi over on the trading post, but I figured I'd ask here about this specific problem. When it went away in storage about 10 years ago, the colours on the display were already off (no green or blue). When I turned it on last night, it showed scrambled colours and video. I cleaned the goo from the leaky caps off the board, and now there's no video output at all (but it boots fine). I assume the damage pictured is to blame. I just wanted to see if it's hard to repair, out of interest. Also, I'm new. Hi.

Posted by: rawkinghorse on 2015-05-16 01:15:54 Hmm. How much would you charge for a recap? Are you reasonably sure that the caps are the problem or could I have put it back together wrong? heheh

Posted by: uniserver on 2015-05-16 02:51:27 well there is only 8 caps to change on there so it wouldn't be a ton. couple things to try first though. 1. double check your monitor is working, those are dying from bad caps now too,  Or  check your DB15 to vga adaptor switches,  make sure they are set for 512 x 384 or 640 x 480 2. pop out vram simms and pop them back in. 3. try to see if you get video with a nubus video card. 4. Check the pram battery voltage, might be one of those macs that get no video when pram battery is flat. -- i'm not 100% sure on this. and if you still want a re-cap just pm me.
