It is possible that your system is gettting overloaded and makes the sfety cicuit switch off . This is the protecction circuit to prevent further damage and fire within the system particularity when the output or power is shorted. Check from the speakers for short remove and test . Also use a multimeter to test for short in the output drive. If so disconnect and see if the protect releases. Then you must replace the outputs. Check also the protect cicuit for a false alarrm due to wrong biasing. Hope this advice helps to figure out. Good day

When I turn on my Home Theater Sony Model hcd-hdx576wf this message appears, "protector, push power". what I can do?


Follow the steps below to troubleshoot if the word PROTECT or PROTECTOR is flashing on the A/V receivers display.
1. Check the speaker wires and speakers for proper connections.
2. Reduce the volume level. IMPORTANT: If the receiver is played back at maximum volume level it may enter the protect mode. Maximum volume listening will cause the receiver to run very hot and may drain the output capacitors.
3. Disable the surround sound option if both the A and B speakers are being used simultaneously.
4. Ensure the top of the receiver has proper ventilation to keep it from overheating.
5. If the message only occurs when using a DVD player, the sampling frequency may be set too high. IMPORTANT: Some receivers provide compatibility with the higher sampling frequencies through alternate connections. Consult the owners manual for specific information.
6. Unplug the AC power cord for about 1 to 2 hours to reset the output transformers.

Protect


When "protect" appears on the front panel display, it means that the speaker protection circuit is in function. Visually check all your speaker connections at the back of the unit and at the back of each speaker as well. Make sure none of them are shorting out. If that is not the problem, turn off the unit, disconnect all speakers, turn unit on and verify that problem is gone. If gone, one of your speakers or wires are defective. If problem persists, the DAV-C450 internal circuitry might be in need of service. Never connect or disconnect speakers with the unit powered on. Hope this helps.

DVDs won't play


Hi Pookie, This is an easy fix. All you need to get is a CD/DVD-Player Laser-Lens Cleaner for about $5.00. You can get these at Best Buy, Circuit City, Radio Shack, or any similar place. Use this, and let me know how it works for you. Best regards, nightdiver
