The general problem with LCD type TV's is that the power supply fails. They are very sophisticated designs that are difficult to troubleshoot and generally best to just replace the module, but sometimes there is visible damage in some of the electrolytic capacitors (visibly bulged) and high voltage rated parts can be substituted.

Hope you already resolve it, if not, here what I went through 1. Try to get a service manual for your model ($10-18) from http://www.service-docs2.com or similar place. 2. Open the back and follow instructions how to remove and test the SDR-D and SDR-U board on the far left (take one off, see if you could see half the picture). Inpsect the chips on those two boards, you might be able to spot the burned out holes (that would be the defected board, seemed to be a known issue for particular models) 3. If it is the board, go to ebay and get the pulled out board replacement ($70-90) I fixed my 50 inch plasma this way

TV won't turn on


It sounds that, the memory IC to your TV has damaged. This IC can be located very near to main system control IC. A very small one, with 8 solder terminals. Even though it is very small, function of it while the TV works is great. The work is a semi-skilled one, and you must have some knowledge in electronics to proceed.

When I turn on my set, light turns green, then after 30 seconds turns red won't come on


Sounds like there is a problem with the power supply. Try unplugging the T.V. and hold the power button for 30 seconds. Plug the T.V. back in and see if that helps. If it doesn't try switching to another outlet, and if that doesn't work then you may need to replace the power supply which would probably cost anywhere from 140 to 200 for one.

The most likely the TV has a power supply related problem. It maybe a blown fuse inside the TV.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.
