I understand the problem. It should be the relay which is not responding, technically not able to connect the system power supply, you will have to replace the relay. The STK chip should be working fine.

SOURCE: I have a Sony MHC

I think grooves are dirty / clogged in sled section of lens mechanism. There is flexible wire between lens and circuit board and this should also be checked as it can be cracked or misaligned.
Below is exploded view of lens in MHC-GX470 and marked area to be checked or cleaned.

SOURCE: I have a Sony MHC-GX470 stereo...it will not play

the mechanism is bad or in human terms the motor that excepts and moves the disc has gone out i reccomend taking it to a repair shop to get a estimate because it may jus be cheaper to replace it.

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.

I have a sony HCD-gx470 stereo an it will not go to the next song by itself how can i fix this


hi, if you are reffering to the cd player section, then check the program or repeat feature. make sure that none of these features are enabled. if this does not help then activate the "master reset" procedure in your user manual. lastly check beneath your unit for any transport locks/screws applied to the cd mechanism. cheers.

The system is always in standby mode and do not turn ON


The problem you are describing is typical of audio output ic problem when there is a high current load the protection circuit kicks in preventing further damage. But lets check a couple things! turn down volume, power off, and remove speaker wires from the back. now power on, if protection kicks in the audio ic needs to be replaced, if it powers up properly checks wires for shorts and speaker issues and hook up one at a time until protect comes on revealing the problem.

I have a Sony MHC GX470. It has been working great since I've had and the sound quality is awesome but since 2 days ago the cd player keeps skipping and it'll restart the song and skip again or it freezes....
