If it really says, "Push power protector", there should be a reference to it in your owner's manual. Check there first.

SOURCE: "Protector" error

I had a similar problem and went to Sony tech support.

Seemed my disc got stuck somehow...

Try reseting the system by holding the STOP and the EJECT and the POWER buttons together...
It should go to demo mode....

Then try PLAY to see if you can get the system to read teh disc...
then EJECT...

It took me several trys of doing this but it did work....on the 3rd try.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance 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.

I imagine it doesn't do ANYTHING you want it to do, much less eject a disc.

SOURCE: Hi Sir , Sony DVD Model

It is possible that the amplifier had encountered a fault with a higher current drain which had triggered it to a protection fault condition. The fault can be your output drivers- the MOSFETS/IC's fitted for both the channels, Use a meter after disconnecting to check for short in the drivers. Disconnect the positive and negative voltages to the output and see if the protect changes. Even a fault in the preamp stages that drives in high current into the output can shut the Amplifier. Sometimes this can be a noise like a HUM or HISS before the protect works. Faulty capacitors in these circuits also can cause similar issues and needs close observation.
You need to confirm and replace the specific stages or outputs. If not there can be issues in the mother board, maybe the protect circuit by itself is shutting off due to a faulty bias , maybe a leak in any voltage/current sensing circuit. Also disconnect the speakers and test, if the protect is off then check for short on the speakers.

Thank you for using Fixya

My device cant open the disc tray please advise me on what to do


Electronics Corporation sells inexpensive DVD players. The DVD players, however, often exhibit problems due to their manufacture and way that they work, which must be dealt with during the course of the player's life. Knowing what these problems are beforehand can aid in resolving difficulties when using the DVD player. In some cases, it can help eliminate the problem before it can become catastrophic



The disc door is not properly closed if the Disc player display shows an "Open" error message. Check that there are no gaps in the door and use the remote to open the disc door. If it will not open, unplug the Disc player and gently pull out the disc door and then push it in. Plug the Disc player back into the AC socket.

If the DVD has not been inserted properly into the disc tray, a "No Disc" error message will come up on the display. Eject the disc and lightly flick off dust using the edge of a lintless cloth. Inspect the disc for damage. Insert it carefully again into the disc tray and use the remote to close the disc door.


Because the Disk player is inexpensive, the power supply is not of the highest quality. Having a surge protector to plug into the Disc player will help to keep the power supply from being damaged over the course of its lifetime.

Have a nice day

If disk door wont open - stays locked


I called Samsung who suggested pushinhg the play button on the panel and the power button on the remote together. "No disc" eventually showed on the screen and pushing the open/close door button worked.

However, my remote wouldn't work, even after changing batteries.
The machine did play. Unfortunately, later that night I tried another DVD and it locked up again. The next day I tried the above 2-step and it worked again, so maybe the other DVD caused trouble. But I cant get my remote to do anything except the 2-step listed above.

I don't use the player very often.
