This is most likely a bad capacitor or something wrong in the high voltage or horizontal deflection circuit

TV turns itself off after a few seconds, no picture at all


I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

1) Could be bad CRT ( picture tube )===no green==purple.

 2) Might be lack of green drive to CRT==bad transistor.

 Recommend analysis by technician--usually worth it if CRT ok.

Samsung PC J5225 shuts down after 3 - 5 seconds


It sounds like the tv power supply has problems. you probably should call a service center about a repair.

there are "safety" features built in to any tv with a "crt" type of screen that will not allow the tv to run when there is a problem.
