I am on the board of directors of a new theater group with very limited assets. We were given a NSI MC 7524 lighting board by a disbanding theater group. It served us well for our first performance. We lost our technician due to his needing to move to new employment, and I have been annointed the new technician, although I have very limited experience. Two days before out last performance, the lighting board circuitry appeared to have fried. I was able to scrounge up two borrowed boards (our dimmers are both microplex and DMX, our board could handle both, the borrowed boards could not) for the production but we are now faced with a decision about our lighting board. I opened it up to briefly look at the circuitry, and it appears that some chips are burned out on the potentiometer boards controlling the channels. The other boards looked fine visually. When plugged in, the board looked like it was going through a continuous loop of a preset program. My question is, is it worthwhile to repair this board, or will the cost be prohibitive? The board was certainly overkill for our production needs, but I have always felt it's best to have too much than too little. The board is about 10 years old and out of waranty.
