SOURCE: Push Power Protector

I had the same. It was caused by the speaking wire ends touching the unit. I was just setting it up and had not fully connected everything. They were just loose. In general i think the message is trying to say check the power or check all your cables for short circuts.

SOURCE: it says push power protector on my new sony surround system

Protect mode will kicking whenever a fault is detected.

Causes that can start protect mode are:

Electrostatic harges on internal circuits.
Leave the unit unplugged for power for one hour or so, this will allow discharge.

Bad speaker wiring.
Check speaker wiring, try unplugging and plugging back, or start after removing one speaker at the time.

Internal fault.
Internal fault is the natural cause for protect mode. If all the above did not work, then the problem is a blown component or an internal fault. In this case the unit must be taken apart , tested and repaired by an experienced person.
If the unit is less than one year old, or if you want to get service, call Sony at the phone number listed on the product documentation.

SOURCE: why does push power protector keeps flashing in

This is an error massage and comes when home theater got some internal problem specially in amplifier output section that can have defective output IC etc.
It is not user level repair and requires qualified tech for fix.

Push power protector

If it really says, "Push power protector", there should be a reference to it in your owner's manual. Check there first.

Push power protector

Do a cold reset, page 90 of your manual. Push power button, stop button and disk eject at the same time. Wait 5 minutes and turn back on. Look on page 90 of the manual. This worked for me after trying over a year. I beat I didn't have 25 hrs on mine. Good Luck

The "PROTECT" and "PUSH POWER" messages will flash alternately when the protective device of the amplifier has been activated because a strong signal was input, or if there is a short-circuit detected. Press the POWER button on the unit to turn off the system, and check the following items after "STANDBY" disappears.

1) Are the + and - speaker cords short-circuited?
2) Are you using only the specified speakers?.
3) Is anything blocking the ventilation holes of the system?

You may also refer to the following link for additional troubleshooting steps.

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.
