I have a Olevia lt37hvs, When i plug it in the blue(olevia)light comes on then goes off and the screen will be blue for 5-6 second then go black for 1-2 seconds then screen goes blue again and it just keeps repeating this process. i hear the big transformer on the power supply clicking like its being overloaded then the screen goes black. When i disconnect the main board from the power supply the clicking and flashing stop. Any ideas?

There's a good chance you have failing electrolytic capacitors either in the power section or the inverter section or both.
Any caps in these sections that look bulged at the top, or bulged/leaking at the bottom need to be replaced.
If you repeatedly turn it off and on, eventually it'll probably stay on, but every time you turn it off, the TV will get harder and harder to start up until one day it just won't.
Sometimes you have to do the opposite to start it up and unplug it for some time and then try again.

If you aren't tech savvy, don't worry, read the rest of this solution and watch the videos.

If you are handy with a soldering iron and can identify the power supply and inverter / FM section for the backlights, an inexpensive handful of capacitors will likely fix you right up.
Match the capacitance on the capacitors. Go over voltage if you can, and still have them fit.
IE - it's not a bad idea to replace a 10V cap with a 16V or 25V or even a 50V, but don't replace a 680uF cap with a 500uF or a 1000uF (unless you are positive it's only doing ripple filtering, and even then, you should go OVER, not under the uF rating).

Most of the caps that go are 10V 1000uF or 3300uF.

I found some great videos of the procedure (for many Samsungs with the same issue) on youtube.

As you can see, this issue spans plasma TVs, as well as large and small LCD TVs and monitors.
The parts are cheap, and skill required is minimal.
Cpacitors are less than a buck a piece typically if you order online from a place like www.digikey.com plus shipping, and they usually arrive next business day.

Most likely the CCFL inverter has been the problem all along....

SOURCE: have sound but no picture

power supply or main board ( possibly missing clock signal)

I have the same TV and had the exact same problem. I had to replace the lamp and power supply in mine to get it to work. Unfortunately...its next to impossible to find the parts, at least the power supply. I found the lamp online and I was lucky to get the online store I purchased the TV from to send me a power supply from one of thier stocked models, but only after I turned them into the FTC Consumer Protection. The TV was sold to me as a closeout but new, as it turned out the tv was a refurb, thats the only way I could get the parts I needed.

Hope this helps and if you need any other information please let me know.

It is either the fluorescent backlight source for the LCD panel or its associated power supply failing.
