Smoking Studio Color 575s

I need some advice and perspective.

I've posted here before on these fixtures but here's a quick recap. I picked up 6 Studio Colors and 3 Cybers...all 11 years old. They were install usnits and ran for maybe 2 or 3 years before sitting idle (I was told). With the collective help of you all in this forum, I was able to combine parts to get 4 Studio Colors working, then get parts and boards for the other 2 to get all 6 working. The Cyber worked straight away.

I've used the Studio Colors maybe 6 times and based on price I bought them for they've already paid for themselves. Last weekend though, I had 3 of them go out in rapid succession. The display lit up, then showed an "S", then gradually faded out completely. And I smelled smoke. Opening them up I see that on 2 of them, the logic board is serious toast...exploded capacitors. On the 3rd, I can't tell...it's still on the ceiling...but it showed teh same symptoms. All 3 were on different circuits. So it's weird they would all toast within 10 minutes of one another.

So here's where I need advice: Should I 1.) send the boards in for repair or relacement, 2) Send the entire fixture for a thorough once over, 3) scrap 'em, or 4.) Other?

As for the perspective, I've heard that the Studio Colors are very reliable fixtures. Were these new I would disagree but they're not. And I really don't know what went on over there 11 year history. I'm committed to several shows with them over the next few months, so I need to decide what direction to go with them. Perspective or comments along this line would be huge right now.

  • Check the belts on the optical module to make sure they are in good order. Then on the cyber, make sure the wiring harness that goes from the power supply board to the logic board is seated well and not oxidizing. Also if you have a clamp around ammeter, clamp around one of the big capacitor wires and while the fixture is powered up and running to make sure you have current through the cap, if not the cap is bad. They do go bad, and replacing a bad cap will save headache down the road. The fixture will run with a bad cap, but they are not as power effiecient.
