It is in protect mode because of component level failure or cold solder connections.

Lucky guess: you have an auto-fuse somewhere on the back of the unit.

SOURCE: sony Mhc GS100 want power up

The unit is in protect mode because a problem was deteected in the final output stage of the amplifier. The pop in the speakers is a god indication that there is DC current in the output stage. This is not a good thing. This is a relatively common failure of all receivers and can easily be fixed by any shop that does audio repair. Expect a parts cost in teh $30-$40 range.

My Sony mhc gx355 stereo red light flashes buthe it's not powering on


Try disconnecting all the speakers, the red light may indicate the player is in "Protection" mode. That mode is triggered by a short in the speaker voice coil or the wiring to them.

I cant get "PROTECT" off my Sony MHC-EC909iP Mini Hi-Fi System.


Disconnect the speaker wires from the unit. If it still says protect when you turn it on, then the amp ic has been shorted and needs to be replaced.

How to reset my sony mhc-gs100??? it keep saying power protect...


Your stereo went into protect mode to prevent complete failure of the amplifier inside that radio. Most of the time this happens from playing the stereo real loud for a real long time and it overheats. Most of the time disconnecting the receiver/stereo and letting it cool all the way down or at least 5 minutes and then reconnecting it to the power source will reset the protection mode. You want to make sure you are keeping the radio cool. Don't stack anything on top of it and try keeping a small fan blowing on it to expedite the heat out from the unit. Also turning it down every now and then to let everything cool down a bit will help prevent it from going into protection mode as well.

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 !

Defective sony vcd Model MHC-VX33


If it havent been use for a long time try dusting it and cleaning it first, sometimes dirt gets stuck on vital places which makes it go crazy. Hope this works. Please dont forget your rating for me as well...We take time in answering problems. Thanks
