I have the same problem. I took the back cover off of the TV and blew all of the dust out and the TV started working again. But this only lasted 2 days. Now the TV is dark again.

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.

Tv will not turn on--- flashing red led


I'm sorry, I don't have a solution, but I seem to be having a similar problem. When I turn my TV on, the green light comes on like it's powered up, but then the TV turns itself back off and the red LED light flashes. I can't do anything to turn it on or anything.
