Why would my power amp go into thermal protection immediately?

    I drug out my PA today. One of my drivecore 2000's is acting up. For a while I got a fault code and no sound. Eventually, it would work for a short while but cut out/cut back in no matter how it was configured, etc. I contacted Crown but it's the weekend and it may be a while.

    Yeah but it's Monday now ;) No idea what's wrong, but at least you can get answers now.

    If it went into protection immediately, it wasn't a thermal problem, but I would check the load before anything else. Look inside of the plugs on the speaker cable(s) and unplug the speaker(s) to see if it goes into protection without a load. If it does, the amp has problems- could be DC at the output, a shorted output transistor, a bad thermo-couple or a power supply problem.

    "Good news, everyone!" Crown is going to repair it under the 3 year no fault warranty. They are paying the freight, sending a new box and packing materials for transit. Awesome!
