Hi mysony stereo system is displaying push power protect on the screen and wont play nothing?can you tell me hat i have to push to like unlock it thanks:)

Generally speaking, an amp protects itself from heat, shorts and overloads by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

What is "Press Power Protect"?

Hi Lois,
Stereo sytems have a protection circuit that alerts you by displaying "protect" when there is a electrical short circuit detected in the system, the most common short happens in a speaker, try disconnectig the speaker wires of both speakers(all speakers) at the back of the system, then play the CD or cassette player(although you will not hear anything with the speakers disconnected) and see if the unit goes into "protect" mode if the problem is still present then you have an internal short circuit and the system will need to be sent in for service or replaced(depending on age,repair costs). I would not recommend investing more than $80 into repairs. Now, if the unit does not go into "protect mode" then one of the speakers or speaker wires is shorted,be sure you check the conndition of the speaker wires before you replace the speakers, then you can replace the speakers(in a pair) and you should be back up and listening! Good luck and Merry Christmas !

"Protect" and "Push Power"

Doiuble check your wiresa again for no pinches or shorts, even at the back of the unit. Also try unplugging the unit for 12 to 24 hours. If that does not help, it may be the time to buy a new stereo because that means there is a fault in the output device, unless you kinow someone who can trouble shoot and repair solid state electronics.
