Power supply likely failed. Electrolytics are the primary culprit.
It should have a switchmode power supply, so it is lmost likely the 5 volt section failed.
Any part of the SMPS could have failed and it either can't power up or it won;t because of the circuit protection built into it. You will have to take it to an Electronics Shop that knows how to repair SMPS's.

SOURCE: Crown XTi 4000 brand new digital amp how can i
Hiya, to unlock press PREV and NEXT until it says unlocked.
The short 1 sounds a little serious though. Have you tried taking off the speakers?? If still there then suggest contacting crown. They have a pretty good no nonsense 3 year warranty
Best of luck
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.
Respectfully, Muzick
SOURCE: i need the schematic for the crown amplifier
These are available for purchase from Crown. Generally they are not available on the web. Is there a specific problem that you are having?
