WHEN THE POWER IS TURN ON GETTING A MESSAGE SAYING PROTECTOR/ PUSH POWER ON MY SONY HCD-HDX285


Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a root cause for ntermittent shutdown.

Sony home theater model no hcd-dz570 push power protect error on display what,s solution?


Check the speaker connection. One of them has a shortcircuit. Try to disconect all of them and power on the device. See what is happen. If starts corectly check the speaker cable. Conect one by one and power up the receiver after each connection. When you get the error again check the last conected cable. These receivers have a protection system against shortcircuits. That is puting your device in that error.

WHEN I ON MY HI FI SYSTEM THERE IS NO SOUND COMING OUT OF THE SPRAKERS, AND WHEN I INCRESE THE THE VOLUME TO 16 OR ABOVE THE HIFI SYSTEM AUTIMATICALLY TURNS OFF. TO RE START THE SYSTEM YOU HAVE TO TURN IT...


There is a problem with the output section. When you turn up the volume, the protection circuit kicks in and shuts down the system. This unit requires service. Expect a parts cost of about $10-$30. Add in the local labor rate for the total repair cost.
