Likely a problem with the amp. Buy a new one and don't run it on full power for too long. Mine got shagged when I had a party and maxed it out for 2 hours.

Read it could be excessive solder on the amp circuit heating up too much then obviously not working after it cools since the connection is messed up when the solder changes shape.

My Sony home theater DZ290K had a push power protection on the display screen how can I fix it?


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?

Sounds like unit is in protect mode. This is usually caused by a problem in the amplifier section. Only way to fix is to replace the main board - hope it's under warranty, otherwise it's probably not worth fixing
