No sound at all, and the mute and solo channel buttons have no effect. If I need a replacement main board is it possible? Should I be able to visually see a problem if it has shorted out? I took it apart to clean dust off the face and the channel area on the top of the board had a lot of dust. Could dust cause a short?
Unfortunately, this is not a problem that will be easily resolved remotely. As far as I know, the main module is not a replacement part. These units are pretty rugged and it sound more like you have a power supply problem rather than a board problem. If you have not worked on one of these before, please do not attempt to dis-assemble one. These are a bit tricky to work on. More than likely, the problem will be either in the power suppy, or be a couple of defective surface mounted op-amp ICs. None of the parts required should be expensive. Based upon your description, I would expect a parts cost in the $15-$30 range.
Where are you located? Perhaps I can recommend a service shop.
