    my stereo loses power or something. I listen to the stereo at a volume 7 for a few minutes and suddenly it would lose volume making it as if the volume was on the bare minimum. I turn up the volume to the max of 30 and it sounds like the volume is at 7.

I also am having the same issue, fuses are good, I think the sub transformer and it's board are good, not much to fail on it... I would like help finding a new direction to go... (gx250)

    the fuses are on the left side of the unit, on the main trans. board. You can see them if you remove the right side panel and look with a flash light.

Sorry insufficient detail...
Have you the power supply in bits?
Have you checked the fuses?
How do you know its the power supply?
Its very difficult to help with very limited information...
Is there power available on the wall socket?

Sony MHC-GS200 does not play CD's and emits a squealing sound when unit is powered on. Sound comes from CD compartment even when Radio is selected. Carousel will not rotate either.

The only way to find out will be to open it to view the CD area. Then power it up. And watch what happens.
It could be a foreign object in the mechanism.

If only demo mode is playing,it's mean set is in standby mode.Normally
in standby mode it can't be operated.You have to power on the set by pressing power botton during demo mode.Once it gets power on,it will
start to work according to user required function.If the set not get power on after pressing power botton,then it's an electrical problem

I have a Sony MHC-GX470 will not play cd's...when you load a cd in it comes up with "mecha error"...the cd changer will not move between cd 1, cd2 and cd3 either.

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.

Dvd not playing.c 31 00 occur

The only thing you can do is get a CD DVD player cleaner with liquid. Found at any store these days, then run it a couple times. If it plays, Problem solved, if not, it must be repaired. They will put a new transport in the unit. Usually runs 100-150 to replace. Weigh the cost to fix vs. the cost to replace and the age of the unit before you get it repaired. Hope this helps

No, I doubt if the surge device is causing your problem. most likely there is a power supply issue, or a fauly with one of the servo or motor driver circuits. This is not a repair or a quickie fix for the end user I'm afraid. This unit is going to need to be taken into a repair shop to be diagnoised. Good Luck
