Hey everyone,
So, I just finished an overhaul of my AudioVision 14", and then turned to my 6100 DOS to get it back in shape. Absolutely no issues prior to recap, just preventative. Caps removed easy: no lifted pads. Replaced them all with same spec 47 µf, 16V organic polymer surface mount caps. No issues so far. Now, when I use the machine, after a while (presumably when it heats up), I start getting all this crazy loud crackling through the internal speaker. I have the thing hooked to the AudioVision and it does the crazy dance through the cable converter via the PC Card cable, etc, and there is a speaker mini plug plugged in the back, so the internal speaker should automatically just cut out. The sound through the AudioVision is crystal clear - it works just fine. It is just the internal speaker with this crazy crackling. It comes and goes, and is worse the longer the machine is on. So to sum up, get good, normal computer sound via the AudioVision while simultaneously getting crackling through the internal speaker.
I suspected some bad soldering on my part, so I desoldered, cleaned, fluxed, and desoldered them all. To be fair, one was somewhat loose. So, I double-checked and desoldered all 13 of them. Started the machine w/o the AudioVision hooked up - got a good startup sound through the internal speaker. Thought I was good, but after 5-10 minutes, the crackling came back again. Not sure what is up with this. Only the caps were touched, nothing else. Could I have accidentally hit something else? Maybe, but what? What else would cause this out of nowhere? Otherwise the machine is 100% functional, and the DOS card works perfectly as well.
Any guidance would be super helpful!
