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?

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

Kenwood VR 605 power light flashes


CHECK FOR CLEARED COOLING VENTS & FOR PROPERLY WORKING COOLING FANS. THIS WILL CAUSE SHUTDOWN OF THE UNIT. IF ITS ALL CLEAR, YOU PROBABLY HAVE A POWER SUPPLY ISSUE.

Shut off on volume 25, and protection light comes on and starts flashing. i unplug it and demo stays on forever till i hit the power button and comes on for 2-3 sec. then shuts back off with red light...


Try reseating all wires in the speakers, you could have it shorting out. If that doesnt work try change the cables. If that doesnt work then try plug one speaker in at a time on different channels to test if it is a short within the speaker or the speaker output.

Denon avr 788 power switches off by itself quickly with power standby button flashing


Could be a short on one or more of the speaker outputs. Try disconnecting all speakers and turning the unit on. If that works without a power-down then you have a short in one of the speaker connections. Re-connect them one at a time to detarmine which one it is, and then you should be able to correct the problem.

If that is not the cause then you have an internal problem with the avr which would be difficult to diagnose here.

The kenworth radio has a button flashing saying protected and wont make a sound


Your unit is either locked with a code, or there is a short. If you have removed power before this problem happened then your radio is locked and you will have to call the manufacturer, if not then your speakers are shorted.

Hello, I have a prob with my Sony HCD-RV999D I just bought it from a friend, I plug the outlet everything is normal, I press the power button, the system turns on normally, but after 3 second it turns...


The reason this happens is because it takes about 3 to 5 sec. for the output circuit relay to kick in after power up, im sure at this point is when your receiver shuts off and flashes red. You have a bad output Transister its shorted to ground and the sony's protection circuit kicks in and shuts it down. Unless you are a electronic Tech. you will have to take it in to be repaired its going to be about 120 dollars to repair. Now im assuming your speakers are ok, if you have them hooked up when you do this try disconnecting them and try to power up if it does you have a shorted speaker, but normally Sony just displays overload protection on the display. Im sure you have a shorted Trans. sorry for the bad news good luck.

The dvr99 3 dvd home theater receiver will not stay on


Protect kicks on commonly when it over heats or when the speaker wires are crossed and it detects a short on the output. Your symptom sounds as though it may be a speaker wire because it happens right after the power is turned on. Check the speaker wire carefully, it has a habit of breaking inside the connectors of both the receiver and the speakers, especially after 5 years of service.
