This kind of failure is very common; that is why I suggest that one should keep the old CRT TV, buy a converter and put them both in the garage or basement so they are handy when our s*e*x*y new sets go belly up.
With fair confidence I can say that the main power supply has failed.
If you want to try this on your own, it only will require the removal of a few screws and a flashlight.
- Unplug the set overnight. - Remove the rear housing - Use some logic and these tips; look for a separate board with larger than average parts on it and seems closer to the power cord than others. This will be the power supply.
Check the board over for something that looks like a part number and record it. If you find more than one, one of them will be the bare board number, the second (sometimes on a sticker instead of printed directly on the board) should be the part number for the assembly.
Search for the Westinghouse service company nearest you and call them with this info. Ask if they repair these or just sell new ones. If it is the latter, don't pitch the old one, continue to look for a repair service that will take it on after you have the new one in place and can watch your favorites again. The new supply will likely cost between $90 - $150 and with a little common sense, most anyone can remove and replace these in the set. Expect any repair to cost about the same as a new supply; US technical labor costs more than Chinese assembly labor.
These supplies can be as reliable as the primitive older type but companies refuse to use the high-grade components necessary to give them a long life so they fail much sooner than the old, less efficient kind known as 'linear' supplies.

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.

It is shutting down may be because of bad power supply or shorts circuits in the backlight inverter board. You will need to do in-depth troubleshootting to narrow down the problems.

Based on the symptoms you are describing it seems like your T-Con board is going bad. This board is located on top of the panel and its main function is to make the pixels properly display on the screen. When this board goes out you can experience a few things and normally red or blue spots in the dark areas is one of them.

This sounds like the inverter board has gone out. The inverter board is in charge of turning on and off the back light. If this goes out the TV is still able to fully function meaning you will still get power indicator to turn on, but since the back light is off you cannot see anything on the screen. You will need to replace this part so your TV can be fully functional again. For more information on how to replace, obtaining the correct part #, and parts as well as price availability please send me a quick email to email@example.com.
