    Just bought DAV-DX255 new, was display system. I receive the "push power protector" message when applying power. I have checked all the speaker connections and the ventilation paths and all seem okay. I tried unplugging all the speakers and get the same result. Are there any more diagnosis steps to perform? What else could it be?

I brought the unit to an authorized Sony repair depot and they concluded that all the power transistors were fried. They replaced the system board under warranty (at no charge) and the system has functioned perfectly since. Thanks for your help. -Steve.

Open your unit up, and unplug the speaker related wires on the backmost board, then try turning on the unit again...some simple soldering should fix the problem!

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

MY SONY HBD-DZ810 HOME THEATER IS CONSTANTLY SHOWING PUSH POWER PROTECTOR


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.
