TV turns itself off after a few seconds, no picture at all
When I press the power button, I hear the TV turn on. What I here is like a relay click, no sound or picture from the TV itself. It will shut off after maybe 5 seconds then turn itself on again. It will do this repeatedly, never do get a picture or sound. Also don't get the sound of the CRT powering up, if you know what I mean.

the relay is the safety protective device..sometimes a defective component or something. maybe an overloaded power supply might caused this problem..so before any thing could gets worst..the relay will shut the unit..
I need to know how long do you have the tv?In the other word,approx. how many hours you have put into it? Secondly,did you wall mounted the tv or setting it close the the area which there is not much room for the back of your tv to breath? solutiondoct
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.
As far as fixing goes, you might as well get a new TV... Unless its a LARGE EXPENSIVE HOLY $%^# TV, It will cost more to fix, than to just buy a new one, unless its under warranty, which being an older model as that (or so im reading) It may not be covered.
Try unplugging the TV, and while unplugged, hold down the power button for a full minute (yes, with the plug NOT in the wall) after a minute, plug it back in, and try. Its a hard reset. If it still does not work, and you've tried different outlets, It's probably a repair issue, and you'll need to get someone to fix it, or just junk it :-/
