SOURCE: push power protector
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.

Push Power Protect is error sign when unit got problem in Power Amplifier section.
Let me know if you have electronics repair experience to help you further as I have all necessary info and schematics of DAV-DZ230 home theater system.

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.

SOURCE: it says push power protector
These Usually a protect fault will indicate a bad transistor in the amplification section. I suspect that the control circuit is sensing a fluctuation in the power supply and going in to protect mode. (assuming that the protect circuit itself is working properly) If a voltage is too high the unit will go in to protect mode to prevent damage to the speakers and the rest of the unit. I would take the unit in to a local repair shop and get a estimate of repair charges. Expect a 60 to 80 dollar repair charge depending on how many parts need to be replaced and what the repair labor rate is in your area.
Hope this help in solving the problem....
