Sanyo AVM-3689G Black screen/high pitch squeal

I have a Sanyo AVM-3689G and the screen wen't black and now has a high pitch squeal. I called out a repairmen, the poor guy took the board back to his shop to work on it but it still has the squeal. The repairmen or his wife could not hear the squeal. It may have been because they were a little old. Do I need to have a younger repairmen come out to see if he can hear the squeal or is it an easy fix.

Maybe you can give me some idea of what component the repairmen should test for failure..

Any help would be appreciated.

Thanks,

Toznov

Black screen, high pitched squeal


A set that has only a 1/2 inch bright line through the middle of the picture, from left to right, has a vertical output IC that is not working correctly. If the 1/2 inch line is in the middle but going up and down, then the horizontal yoke circuit has stopped working. These are problems which should be looked at by a qualified tech, but if the set was purchased 6 months ago then it should still be under the manufacturer's warranty.

Squealing set


It looks like an output transistor problem. You can't fix it by yourself; you will need to call a service. It will cost you at least 100$, so consider buying a new one good luck
