What additional info do you need?
Expert:  Shahid replied 4 months ago.

Working on it and get back with you in 10 minutes, is this OK?

Expert:  Shahid replied 4 months ago.

Thanks for waiting, we need to get error code form TV which will help to determine the cause of problem.

Turn On TV, let green light blink and stop itself. Now press Device and Menu buttons on TV front (not on any remote) for 6 seconds to activate error code reporting, the indicator light on TV will start flashing in 2 digit pattern to present error code, for example, 2-3 code means light flash 2 times, pauses, flash 3 times, pauses and repeat the blink pattern.

Do you get any error code form TV?

Customer: replied 4 months ago.
The device code I get is two green blinks pause then one green blink
Expert:  Shahid replied 4 months ago.

OK, so the error code is 21 and not 12, correct?

Because my answer would be based on that error code.

Customer: replied 4 months ago.
21 correct
Expert:  Shahid replied 4 months ago.

OK< this error code calls x-ray protection and possible cause is high current drain in power supply or deflection circuitry of TV, it needs further troubleshooting inside TV with multimeter to sort out bad parts causing the problem to get them replaced if those parts are still available with any supplier because looking at age of TV (2004 model) it would be hard to get replacement parts. Please reply back if you wish to troubleshoot the issue yourself and have multimeter and can use it to assist you further.

I'm sorry there is no easy or quick fix for this problem and it is definitely hardware failure that needs defective parts/ board replacement to resolve the issue.
