I went turn on my tv the picture came on then off


Picture turned Yellow because the Blue CRT stopped working. Power turns off because the power supply is indicating a fault. you probably lost your HT (high tension [voltage]) power supply on the blue CRT (picture tube). Professional assistance is recommended. HT power supply CAN DELIVER A LETHAL SHOCK even when the set is unplugged.

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
