SOURCE: sony home theater system started blinking protect

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.

Regards.

SOURCE: My Sony Home Theater system

MHC-DP900D HAD SAME PROBLEM- PROTECT, PUSH POWER. TRACED CAUSE TO AMP. DC PROTECTION CIRCUIT ON AMPLIFIER BOARD. ACTUAL FAULT WAS A SHORT CIRCUIT OF THE AMP. IC LEFT CHANNEL OUPUTS (STK412-030 PINS 10 & 11)
EXCESSIVE SOLDER APPLIED DURING MANUFACTURE HAD PROBABLY BEEN HEATED UP ENOUGH DURING USAGE TO BRIDGE THE PINS. CURRENTLY USING THE UNIT WITH RIGHT CHANNEL ONLY UNTIL I PURCHASE A NEW IC. BYPASSED DC PROTECTION FOR LEFT CHANNEL BY ISOLATING INPUT TO DC DETECT TRANSISTOR.
This is what I could find, it looks like it will need serviceing unless you can do it yourself, it can be deadly if you don't know exactly what you are doing.
Thanks for the fixya rating, hope this helps

Check the speaker connection. One of them has a shortcircuit. Try to disconect all of them and power on the device. See what is happen. If starts corectly check the speaker cable. Conect one by one and power up the receiver after each connection. When you get the error again check the last conected cable. These receivers have a protection system against shortcircuits. That is puting your device in that error.

Hi ,pls my sony Bdv L600 3D home theater does not give me any sound even when I turn de volume high.Pls I need help to solv th problem,thnx.


There can be many problems causing this. Check to see if you have everything switched correctly, including inputs that can be analog or digital.

Try this. Disconnect the power to the unit. Plug it back in. When you first push the power button, you should hear 1 click followed by a second click within 5-10 seconds from the unit itself.

Once you have this information, if you are interested in having your Sony repaired, please contact me at my website, audioserviceclinic.com. Thank you.

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.

Have a SONY DAV DZ370 Home theater system. Displays 'Push Power Protect'. Tried 'cold reset' and all the manual stuff to no avail. Should I reset the M16C micro-controller or is there...


Push power protect is an indication of an output failure ( Amplifier ). The Home theater system is asking you to switch off the power to prevent further damage. This mode is called protection mode and you will need professional help sort it out.

I m receiving a message push power protector


That is an internal failure message . The system is telling you either your speakers are shorted ( even cables could have shorted ) or the internal amplifier Chip has failed. its is asking you to switch off the system by pressing the power button to prevent further damage. You will need professional help to replace the STK power chip.
