Most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you red light flashing codes, circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

Hello! I'll need the trouble code to fix your vehicle...Below is procedure with a code list...Guru...saailer

Remove the trim panels in front of the center console. Locate the engine computer attached to a floor-mounted bracket on the transmission tunnel between the console and the firewall.

  • Turn the diagnostic mode selector, located in a round opening on the side of the engine computer, until it stops. Observe the small red and green LED lights on the side of the computer next to the mode selector. They will flash to indicate the modes, with a pause between each mode. One quick flash is mode one, two quick flashes is mode two and so on. When the light flashes indicate mode three, quickly turn the mode selector counterclockwise until it stops. You have entered mode three diagnostics.

The red light flashes to indicate the "Tens" digit of the code and the green light flashes to indicate the "Ones" digit of the code. For example, if the red light flashes two times and the green light flashes seven times, this would indicate code 27.

    No Picture & No sound. Red LED, Green LED, Red LED.


    If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.

      • Turn the console off.
      • Unplug all the power and AV cables from the console.
      • Unplug the power cord from the wall socket.
      • Firmly reconnect all the cables.
      • Turn on the console.
    3. If these steps do not resolve the behavior, turn the console off, remove the hard drive, and then turn on the console. If the 3x Red LED error light is no longer displayed, turn the console off, re-attach the hard drive, and then turn on the console.
    4. Also examine the lights on the power supply. When you turn on the console, the power supply light should illuminate green even if the three lights on the RoL flash red.
