Title: New TurboExpress has a missing traces and is all sorts of messed up
Post by: team_andromeda on September 05, 2015, 09:05:06 PM: On the positive end, to be more specific. Is there anywhere else I could connect this cap? Previous owner didn't finish recapping all of them and the system is completely dead.

Also, this is my first post after lurking a short while. I was excitedly waiting for my broken TE in the mail while I read up on it, I didn't know someone had already attempted to fix it before.

Post by: team_andromeda on September 06, 2015, 05:54:59 AM: Thanks! I checked that out and it looks like the previous owner tried that and failed. Before I cleaned up the mess I tried turning it on with headphones in and I heard music, but now after cleaning it up there's nothing. Somehow the huge blob of mess made a connection somewhere and its gone now.

I noticed he tried to use another hole for a different cap on the other side of the board but its a pretty big mess. I'm not retarded with a soldering iron, but I'm hoping I can handle fixing this. Seeing these pics, is there a process you guys could recommend? Sorry for being the noob with a million questions.

Thanks for the input! It looks like the trace for the neg side of that cap is gone, is there another place to solder it?

Thanks man. I'll keep looking into this to see if someone elsewhere ran into this issue, and can recommend a specific point to solder to; I'm weary of picking points at random!
