Hello. My name is***** can help you with your question.

The way to check to see if this is an inverter issue or backlight issue is to have the TV on and shine a bright flashlight onto the screen. If you can see a faint image on the screen, then the issue has something to do with the backlight or the inverter boards. If the screen is completely black, then I would have to be something else, something most likely related to the power supply. And if that's the case there is one particular issue that comes up on this model frequently. The culprit is integrated circuit Q880 #23135089, part number of IC is STR-W6765. It is attached to a heat sink and soldered onto the power supply circuit board (upper right hand corner as viewed from back of TV).
