In most of the case, the problem is defective back light LED strip (Strips).

SOURCE: Screen turns black and blue LED is blinking

Sounds like the monitor is being made to show a resolution it does not support. Check the available resolutions the monitor supports and then check what resolution the video card is giving, if it not compatable, you get the black and blue screens.

For the video card, right click on the desktop in a an empty area and choose properties > settings > your resolution from the card will be there. Now from there click on advanced > click on monitor and look at the monitor settings. Make sure the box is checked to hide modes the monitor cannot display. Now click on the adapter tab and click below on all modes. This is the list of all modes that both the monitor and the video card argree on. Make sure the settings in your game match one of these and you should be good to go.

SOURCE: westinghouse LTV30w2 has blank screen and audio

What you have is a darfon V144 board (junk). it's a simple fix if you know how to use some basic tools and a soldering iron. Get an led (i used digikey's PN: L10041-ND) and solder it from pin 10 to pin 16 on the OZ960 chip on the inverter board. If you need the chip layout type "OZ960 pdf" in google. Hope this helps.
