Thanks very much for asking. This was the first time I've ever attempted something like this from a web-site. The fix posted helped me very much. For the cost of the 2 capacitors from Radio Shack and a cheap soldering gun I was able to fix the problem in about 30 minutes. The pictures were the key.

Look at the power supply board, look for capacitors ( look like black or brown cans) that have their silver tops bulging. There is a cross on the top designed to open in a failure so the capacitor doesn't pop. Even if the top is still closed, the slightest bulge indicates a failure. Unsolder all bulging capacitors and replace with same spec. For instance, in a bad Samsung there are 4 1000mf 25v 105C rated caps that always go bad, same symptoms. The caps are about $3-4/pc in USA.
The cause of that problem is a faulty power supply.There's a leak capacitor in the power supply that's why the output voltage of the power supply shut off.There are 4 regulated output voltage of the power supply, the stand by 5vdc,the switched 5vdc,the 12-16vdc and 24vdc.So if any supply output of the following output have gone, there's a problem in the operation of the TV.The leak capacitor can identify throug visual checking if do not know how to use tester to test the deffective parts.The leak capacitor have bulging tops,so if you can see the power supply located at the upper right side you can see the bulging tops of thecapacitor.Replace with the same value of capacitor.
Your power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

jtoddweaver, Check out some YOUTUBE videos of lcd monitor disassembly and lcd monitor repair so you will know what you are looking for that is bad on your unit's "switch-mode-power-supply" printed circuit board. If you do the repair to the board, please document your "tear-down" with video or digital still pictures so you can complain to OLEVIA about poor quality capacitors they installed on power supply and also aid in the reassembly process. Do some reading in the fixya profiles of "budmrtn" "buddymc" "12fixlouie" and follow links you find there. Bye for now 12fixlouie
It sounds like you have a power supply problem! You will
probably find some bad caps (capacitors) on the board. They will look
bulged on the top an may be a little leaky (brownish stain). In addition check the ribbon that feeds the lcd controller.
It is the capacitor. It is really easy to fix, and it will cost you about $4. The capacitor is on the power board and it looks like a small battery. The bad capacitor will have a small bulge on the top, the good ones will be flat on top. You can buy them at Radio Shack. Just look on the side of the capacitor to see which one you will need. If you need any further info I would by glad to help. I have a 40in polaroid that this happened to and it works like a dream now.
Open the back of the TV,and look at the can shaped items on the board that the power cord is hooked to.If any of them have the tops,or bottoms bulged out,they need to be replaced.This should get it working again.So far I have fixed four of the same make,and model TV as this,and they all had either one,or two bad capacitors.I hope this helps.If you have any other questions,please let me know.Thank You very much!
