20 Most Recent Chauvet Intimidator 1.0 Dmx-600 512 Scanners Questions & Answers

I have 6 of these in my lighting rig, and the most common problem has been a bad bulb socket. If your bulbs end up with corroded or blackened terminals, you should replace the socket. The black/corroded stuff can cause the connection to become intermittent, sometimes so badly it entirely doesn't work. The other common problem I've seen involves a resistor on the circuit board that powers the light bulb. I believe it's R2 - regardless it's the only big one. It's value is .5 ohms at 3 watts. Be sure to use a flameproof resistor when replacing it, and most likely your fixture will light up again.

The ratings are normally stamped into the end caps of the fuse. Sometimes they are a bit hard to see. Make sure you repair the cuase of the failure before replacing.

Contact the maker for support. It sounds like they are faulty.

Have you got a terminator on the far end? If not this is probably the problem.

The most likely case is that one of the main output transistors (if which there are many) is shorted. When the protect circuit senses DC on the final output, it will not allow the output relay to come on to protect the speakers from raw DC. With the power removed, you can check between each outputs Emitter and Collector and you will probably find close to zero ohms. From that point you need to unsolder each of the pins of the bad channel until you find the shorted device(s) and replace them.
