I apologize for the delay as I am just now seeing your question. If you still need help, can you please reply back with the following:

1) Are you a DIY type and able to use/have a multi-meter?

2) Or are you looking to see what the most common cause of this is, and a link to the most common part that fails?

3) Alternatively are you simply looking to see what causes this and how much it costs to repair?

what is the cause and how much cost to repair.
Expert:  Aric replied 2 months ago.

Thank you for the reply. The cause is a toss up between either the power supply/LED board, or the LED light strips in the screen itself. Since yours does initially light before going black with shadows, it is more like the power supply LED board is the root cause. The average cost for this repair is in the $200-$250 range, and almost more cost effective to replace the set versus repairing it. However the other potential cause (the LED light strips in the screen) will cost more than the TV did when new to repair as it entails removal of the screen, and then disassembly to replace the LED lighting. I would carefully consider whether or not it's money well spent to pursue repairing this set I'm afraid.

Other than that, I'm sorry for the bad news and wish there were a quick fix.
