Yeah, it can be fixed. Let me know when Tv goes to Off, how many times its Standby light blinks?

    5 times blinks shows "failure of White Balance", it means there is some thing wrong with Picture Tubes drive circuits. Now come to TV problem, as you said, its turns green and go to standby. It shows that Green Picture Tube is cause of problem. Please check its drive circuit like Green Drive IC, related voltages. If all found OK, Green Picture Tube (CRT) itself is defective and need to be replaced. Hope this info will help you out.

On stnandbymode never start SONY KP57HW40


Try connecting the TV directly to a different wall outlet and check. If the issue persists, try power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue persists, then the TV requires service.

Picture turns green ,usually within 10 minutes of turning it on.It will sometimes go back to normal color but generally returns to green.This happened when the set was much newer and Sony replaced all...


Green Tube maybe trying to short out or you can try adjusting screen drive to the Green Tube by turning control down a notch, Sony had a bad run on these with alot of Bad Tubes.

There is a sub-board in this set that powers the convergence circuit. Often a big Ic shorts, two diodes and finally the main fuse. not something you can fix yourself.

Sorry to be the bearer of bad news but I have the same model Sony with the same problem it was just returned from the repair shop (not to mention a $95.00 diagnosis charge) I was told that it will cost $700 to repair. The bulb in the back is gone and Sony no longer makes it so it would have to be re-built from scratch. I'm done.....
