Question about Philips Magnavox 27MS343S 27" TV
MY TV TURNS ON BUT WITH IN A FEW SECONDS IT SHUTS ITSELF OFF.I CAN TURN IT BACK ON BY PRESSING ANY OF THE BUTTONS ON THE FRON ,VOLUME,CHANNEL..ETC......I HAVE A PICTURE AND SOUND ...BUT THE TV ACTS LIKE ITS TRIPPING A BREAKER OF SORTS...
It sounds like you may have a G1 intermittent short in the picture tube, which unless it is still in warranty would not be worth repairing.

Most likely the volume down button on the front of the TV or the switch that it activates is sticking. Should be an easy fix otherwise.

first place to start on this chasss is with a known failure in the horizontal circuit. there is a capacitor 2455 and 2 transistors locations 7461 and 7463 that have caused a wide variety of failures. i would recommend replacing these components before proceeding as they could be the whole of the problem.

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.
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
