Sir my sony stereo system showing "protect push power" how i troubleshoot the problem please replay fast


Protect Push Power on a Sony is telling you that you have an output short circuit and to turn off the player to prevent further damage.
Check the speaker cables for connection fault. If all is OK it means you have a blown STK Amplifier Chip. Will cost you about 20$ plus labor.

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.
