I tried posting this on Chauvet's tech page, but something is wrong with the captcha (or maybe it's on my end). Anyway, it's easy enough to throw it out here and maybe if @Ford is around he could share his $0.02.
Got an R2 Wash. LEDs went out, but the fixture still powered on, moved, reacted to DMX like normal. Took it apart to find that the voltage regulator at U19 on the driver board was burned up. It looks like it's supplying the 3.3v for the micropro logic, so that would definitely take out the LED array if it can't parse anything from the main board. The LEDs themselves appear to be fine. Fixture is out of warranty so we tried our luck at just replacing the regulator which fried quickly. Figuring there's a dead short somewhere, but was wondering if this is a common failure. I found this page that had a pretty good writeup on these fixtures, but doesn't say anything about the voltage regulators.
Easy enough to just replace the board, but where's the fun in that?
