    Turns off and sometimes back on by itself, or just turns off and will not turn back on for a few minutes. Also makes a "crackling" sort of sound when turning itself off sometimes...

The front buttons are common for going flaky - if you remove the front grill you should be able to unplug them and use the remote only
if you use the buttons let me know and i will look up the board or switch part # all switchs will need to be replaced
thanks

Does the Tv pick up a signal ? ( picture/sound ) If not, you may have a tuner problem as the screen will default to blue with no signal apparent. Could also be a cable problem. Hope this helps

Please Help!


A chirping sound from a TV set is the switch mode power supply trying to start up, but gets shut down because of a major short inside the set or in one of the circuits.. Most likly in this set, the horizontal output transistor is shorted because of a defective flyback transformer. Thats whats the common problem is with this set. A repair like this, if this is the only parts that are bad, will run you about 300 to 400 bucks or so. In some cases, not many but a few times, I have seen poor solder connections on L401 cause the horizontal output transistor to go bad. There are no user replacable parts inside this set, so please play it safe and seek out a pro to assist you in this repair. Good luck PS Please do not forget to rate this thread.
