I have an Olevia LT37HVS, which is out of warranty. When I turn it on the screen comes up blue, but no picture, then it turns itself off and then back on to the blue screen then back off continuously.
I have called Olevia, and they first said it was the LCD Panel which I highly doubt. Then I suggested that it was the Power Supply, and he said no it wouldn't turn on at all if it was. Then he put me on hold to look up the price of a panel, which they can't get anymore. Then he came back and said it might be the Power supply, which is $102. I tried to order it, but they dont have any right now.
I took the back off the LCD and unplugged the LCD Panel from the Power Supply Board, and who would have guessed it does the same thing. So I am sure it is the Power Supply.

tried to connect again the supply for main board and disconnect the supply for the inverter board of back light. and turn on the tv, if the indicator stay the inventer board was the cause of voltage drop at the power supply board.
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
you have a broken inverter board. I have a LT30HV, and it had the same problem. The inverter board supplies power to the backlight. Swap it out with a good one, and you're back in business.
To test, take a bright flashlight and point it at the screen just an inch or so off the surface. If you can see your picture, then you have a blown inverter.
it may not be worth fixing it. Wait for a good sale on a new one. My inverter cost about 150, and it was a remanufactured part. Not as good as the original part as it flickers just a tad. I had to take the entire TV apart, with pieces literally everywhere. My cats loved it.
