How to fix push power protector Sony DAV-DZ870W


try disconnecting all speaker wires from the main unit, then turn it on. If it still goes into protect - then the amp is blown and you need to replace the main board.

On switching on the home theatre, message flashes "PUSH POWER PROTECTOR' on the display screen and nothing works


Generally speaking, an amp protects 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.

Protector and "push Power"


Please check speaker wires should be properly connected and not touched / shorted.
Push Power Protect is error sign when unit got problem in Power Amp area and mostly its Power Amp Out IC failure.
I would suggest to ask Sony for warranty cover.
