Every channel on my Tascam 388 is now like it's stuck in Mono. The ability to pan went out while powering up, (Mono button is rarely used and not stuck- not the problem). All pots refuse to pan anything. Only the overall volume is slightly decreased when L/R, (strongest in the middle). I know this is an easy fix, just need to know what/where. Can't even remember the last time I used touched the Mono button, plus- when I now press-it, it still makes that small click and seems to activate, (even though it sounds pretty much the same), so I know thats no the prob. I know the problem is internal because the meter is only registering in mono as well. I've been doing a lot of work on it lately, even had a bulb in the meter go out on me in the same week!, (funny how they look like a missing tooth). Nothing out of the ordinary. Shortly before that, I powered up my power-conditioner, not realizing the mixer power-switch was already turned on (so it immediately lit up, not THAT big of a deal I would think,,,). And that's all I can think of. Never any problems ever and I just flipped her upside-down and cracked her open (she likes it rough sometimes), and cannot see anything out of the ordinary. I'm stumpted. If anyone know what to check and where, PLEASE leave some info, I'm begging you. I can replace caps, resistors, PCB boards etc, just need to know where to start looking. Thanks a bunch guys! P.S. JUST finished Tracking a clients project that still needs mixing!!! Pleeeeease help!
