SOURCE: My 42"LG 50 TV will not turn on
One important step to see if you are having an internal problem is to perform a power drain.
1. Unplug the product's power cable so that the device is not grounded to the house. Do not simply turn off the power-bar if one is in use.
2. Press and hold in the products power button for 1 minute to release the retained electricity from the capacitors and circuit board. 3. Plug the product back into the wall outlet rather than a power-bar to rule it out of contributing to the problem and turn the device back on.
If this does not work but you are still seeing a LED lit up, there is probably a problem between the TV's power supply and the mainboard and service maybe required.

I had a TLX-4240B 42" Polaroid LCD TV and the screen would go black after about 10 minutes. There was still sound. I removed the two covers exposing the circuit boards behind the TV. I powered up the TV and waited for the screen to go black (I was going to start trying to pinpoint where the issue was with my trusting meter) then noticed a red light would come on when the screen would go black. there were 4 mini switches right above the red light. I switched the one that said burn and the TV has been working great since. good luck and let me know!

I first changed the 220uf capacitor with no luck. I flipped the BURN switch to on and the set has been working great for a week now. Daughter left it on for about 20 hours overnight with no problem. Anybody have an idea what those 4 tiny switches are for? I have heard these type of switches called "dip switches". They are tiny white switches in a yellow block on the lower left side of the upper circuit board. The top one was labled 40", the next one down was labled 46", the 3rd one was 4 letters "EW" something I think, and then the bottom one was labled "BURN".

The problem is a faulty inverter kit (2 boards).
I live in the Netherlands and had it twice, tv is 2 and a half years old! In the Netherlands Philips replaces the inverterkit without any
costs for the consumer (even after warranty time) cause they have
admitted that it is a production fault.Philips made a new inverterkit
which should solve the problem indefenit.Be sure the kit is Version
1.3! I had 1.2 after the first problem, and that went wrong after 7 months again. Today got revision1.3 installed which is Philips final solution.
