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.
I bought two Olevia brand TVs last year on Black Friday at Target model
# 237T, 37". One of my tvs wouldn't turn on at all nor did it show the blue light. So far, I haven't call the company yet. But my husband brought it to a local tv repair place, they said it's the power supply board got burned out or something. I thought Olevia was a pretty good brand,but i only have this thing in less than a year and it's already giving me problem.I bought two Olevia brand TVs last year on Black Friday at Target model

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.
The high pitched noise is coming from the Tcon board. It is not properly decoding the signal coming form the main board correctly. The only way to fix it is to replace the Tcon board. You might have a hard time coming across the part because Olevia has since gone out of business. Also, usually Tcon boards are not available sepertaly and most manufactures make you purchase the whole LCD panel of which the Tcon is included.
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.
If your LCD is 8 months old, still under manufacturers warranty. I would call them back and ask them to provide you with a telephone number of their nearest service center to you and have it repair under warranty. The failure is with the video board or main board.
Good Luck.
Try selecting a different input, or checking the device which you are receiving the signal from. A blue screen typically indicates that there is no signal.
Sounds like a bad system board. Start with Olevia for warranty status, and if it's not covered, check for part numbers on the boards for purchase/repair.
