[Console Repair/Mod Center / Re: Sound problems after recapping my Turbo Duo]

I got a Turbo Duo with sound issues last week.  It sounded fine for about the first 5 minutes, then it started to fade and get crackly.  Not unexpected, since it was never re-capped.
I finished re-capping it today, but it's still having sound issues.  Now, the right channel has decent volume, but it's still crackly.  And I've got nothing at all from the left channel.  But if I plug in headphones, it sound just fine through them on both channels.

I did a pretty good job with the caps.  No lifted pads or anything.  Along the way, I found 3 broken vias, which led underneath IC503.  I removed the chip as carefully as I could and repaired the vias, but I can't be sure I didn't damage the chip with too much heat.

Any advice on where to go from here?  Does this sound like a problem that IC503 could cause?  Or is there something else I should be looking at first?
Thanks!

I'm having similar problems as you.  Your best bet will be to remove the 3 op amps IC506, IC521 and IC5xx (the 8 pin op amp beside 521), and clean the areas around them throughly, jumper any corroded vias, and check for continuity between the op amp and areas close by.  I had a bad trace that looked fine.

I have the same issue with mine.  A friend of mine recapped it.  Cd audio doesn't work but you get turbo hucard sound and music.  Just no cd audio.  He tweaked the laser on it and everything but he isn't sure what the problem is.

The only thing I can suggest is to thoroughly check for continuity in any of the areas where the caps leaked.

Cool thanks.  My friend is looking tonight for any bad traces, etc
