It runs off a protected power source. I have 2 same amps this is the first time i ever had a problem in 5 years.
SOURCE: Crown ce 4000 amp wont work
Crown CE amps have a very decent service manual that give test points to check for faults. In these amps protect mode is a good sign that major components are not burnt out ie, (Transformer).
With a good Digital volt/ohm meter most common circuits can be checked against the service manual specifications. Usually in these amps the Zener Diode or Capacitors are the first to burn out along with cooling fans. That would be a good place to start.

Do you get any Fault indications?
Have you swapped the speakers around to eliminate them as external causes?
When the channel dies is the unit very hot and is the fan turning very fast (it should be if hot)? The fan could be defective, slow or airflow may be restricted.
Turn the amp off and examine the fan guard on the rear to make sure it is clear of dust and debris. Vacuum it out if necessary. With a small thin non-metalic object reach in and test the fan for free movement by trying to rotate it. It should coast.

Most likely one or more pairs of the output transistors is shorted. The amp is attempting to drive a signal into a 0 or low ohm load. This unit should see a service center for repair.
