I bought the TV on Black Friday in 2011 from Target. It has worked fine ever since I bought it. This morning I was playing a game on my XBox 360 without any issues. After finishing the game, I turned the XBox off and went to the shower. The TV eventually turned itself off from there being no signal from the external source. A few hours later after returning from the grocery store, I tried to turn it on to watch a movie and the screen would not turn on. If I hit the power button, the blue light would come up showing that it was powering up. Nothing else happens, though. If I push any buttons on the remote or side of the TV, nothing happens. There is no sound or picture. I cannot switch to another input (Component, TV, HDMI, etc.).
Replace the inverter board or back light www.shopjimmy.com
SOURCE: power button is green - no blinks / no picture / no sound
Unplug it from the wall, wait 2 minutes and plug it back in. if problem still exists, its probably the main pcb.
SOURCE: Can not access menu or input functions
Hi rduncan27,
I will be happy to help. 88% of LCD tv problems are with the backlight, the symptoms you described indicate a probable inverter malfunction.
Lets do a simple test to check the functionality.
Let me know your findings and we can proceed from there.

LCD's use a colorful crystal see through display which only visible when light is shining through it. if you have sound and no picture it's always a faulty PSU. Very easy to change out actually.
SOURCE: I have a Westinghouse W3223 TV which has decided
This going to be tough one to figure out, but at least the back light inverter board and power supply are working, unhook it at least 1/2 hour?

I can also see the input/volume screens if I put a bright light right up against the screen.
