I suspect that the capacitors in the power supply are faulty. Unplug it, open it up and look for burst caps. There was a bad batch of capacitors sold during the years that your device was made and it is easily repairable if you are able to get new caps and have some soldering skills.

Be careful, I am not liable for any mishaps as a result of you using this advice.

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.

I have the same unit, although it's a bit old now. I used to get that problem, and the protection system is to protect the unit from over-heating, and the main cause is its because the unit is getting hot and/or there isn't enough air going through the rear of the unit. I found a fan or better air flow helps.

Sounds like you have a short in the unit. You will have to take it apart and check the power supply for bad semis. My best guess is that your problem lies in the power supply. Let me know how this works out.

Power Protect still comes on now and again

Amplifier output chip in stereo is defective and unit gives error message of push power protect.
You need to replace output amplifier IC and check supplied voltages.

Worth replacing?

No you dont need to replace the intire power supply.its very easy to repair you can do it checked all the diodes ,for forward bias ,and for shortage and next the the capacitor for shorted, or busted you can see the apearance change,I know your is good because when put the fuse is blown away resistor good,only the diodes near in the transformer.and if see a transistor with heat sink check that maybe short also ill try to find a shematic diagram for you.
