Switch off the amplifier for some time and allow it to reset. disconnect the speakers and reduce the volume level before you put it on. If the power does not come on you will need to probe inside. Get help if you are not familiar but check on the power lines coming in for failure of fuse, the secondary power supply section transformer or the smps power. Hope it would not go further to this but check this out.Check for shorting inthe outputs, if so disconnect and test. Good day

The only component I can think of that fits your description is a bypass capacitor for filtering high frequency interference. That should NEVER get hot. This amp is going into protective shutdown. This unit should be brought in for service. Continued attempts to run this will end up causing additional damage. Where are you located?

Almost anything. Take it to a Crown Authorised repair service.

If you have eliminated any shorted speakers, cables etc, then the only other cause is a shorted device on the power output board. Probably a device on the heatsink.

  • Open internal fuse
  • Defective power switch

Hello, Sylvia -

I have no idea what entity you meant to receive your question.

You posted in the Fixya.com website, which is intended for asking and answering questions on how to go about REPAIRING THINGS. Plus, your question landed in the Fixya category for Crown (brand) Audio Players & Recorders.

Perhaps you meant to message Netflix, or your local public library, or a person from whom you borrowed the DVD, or someone to whom you sold the DVD, or . . .

Best wishes.

The fan does not start to spin until the ambient temperature increases.

Is the fan supposed to be on. On some units it runs all the time on others when the temp hits a certail level. Which is it for your baby?

It's best to assume there is a short circuit in the power amp board. The unit is going in to protect mode to stop it blowing fuses etc. Could be caused by bad speaker wiring or connections by the way.
