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.

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.
