I would say to check your manual, and if not, get it repaired (if you can). If you need to use a last resort, then just replace your dvd player with a new one.

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.

Button standby


The receiver is in protect mode, most likely due to a damaged amplifier. This protect mode, keeps the unit from turning on and causing further damage to itself and/or your speaker system. For more information, please visit my website at audioserviceclinic.com. Thank you.

When it switches on it says protect and switches of


If protect is coming up on the display, it means the system is detecting a short somewhere on one of the speakers and so is turning the amps off to avoid damage.
Check all the connections at the back of the amp to ensure they are not shorting, and at the back of each speaker, if nothing is found there, check each wire for damage (like squashed or rodent damage).

When i switch on my samsung HT-Z110 the word hello appears then protect thenit turned off!


Audio receivers have an output protection circuit called "protect mode", this is to protect the receiver from short circuit failures.The speakers and speaker wires are what I inspect thoroughly first, look for bare speaker wires,or bare wires that are touching each other at that point,check speaker wires at the back of the receiver for sloppy connections,etc.If all looks good then try disconnecting all the speakers at the receiver,then turn power on to see if it goes into "protect mode", if it does the the receiver probably has an internal short and will need to be sent in for service,if it doesn't go into "protect mode" then connect one speaker at a time back into the receiver until it does go into "protect mode" then which ever speaker you connected last is the speaker that is shorted(blown) and then you know that speaker is the problem and it will need to be replaced or repaired. Good luck !

Make sure none of your speaker wires are touching, this will cause it to shut down instantly.
