Sounds like you've got a problem with either the Drive Motor, Drive Controller or Drive Belt.

It could be an easy fix but it depends on the where the fault is.

Does it make any noise or effort to open the doors?

audio amplifier IC fried need to be replaced

Wow, mine has the same problem - let me know if you figured out how to fix it. <!-- from fixya rte -->

you know electronic devices are usually affected by liquid substance when they are at work.At the moment the tea poured on the system,should you have switched it off immediately,the problem would have been a minor one.However, since you left the system on, I think the system panel has been greatly affected and needs repair.You will need to take it for repairs, but you could try loosing the panel and drying it with a heater or by sun, then fix it back in place to see if it works,ok

put in ur model number and goole 4 ur manual simples

possible laser contamination. do your other c.ds play ok?

If you already tried it with a known good clean cd, try using lense cleaner. If that do not work you are out of luck because that means the laser assembly is defective already, and replacing that is very difiicult, whats more they are an expensive part, costing anywhere from 50 to over a hundred bucks. Lastly they are hard to find for a particualr model.

The "volume control" on your Aiwa is in fact what is called an "encoder". These can fail. They work in concert with the microprocessor to control the electronic volume control IC. Yes this part can be replaced. Try calling Sony with your model number and request the part number for the volume encoder. They should be able to help.

any sony music system problem

I have a Sony MHC-GX555 stereo and every time I try to open the disc tray it either flashes EX-Change or mechanical error and it won't open.

the only thing you can do yourself is leave the set unplugged for over an hour, this will reset it to factory settings. If that does not do the trick it will need to serviced. Chances are if it is a rear projection set that the convergance board is dead. This would be more to fix than the tv is worth.

If you are a technician desolder the audio amplifier Ic and check if the device turn on
