I have the same model with the same problem. Has anyone found a solution as of yet?

I would be checking voltage and caps on mainboard. Marginal or fluctuating voltage somewhere

Deleted comment. I was thinking this was a different board.

I have the same issue (the exact same issue with my tv) that is the same model - I already bought a replacement TV but the point is - I am looking for the satisfaction of figuring this one out myself. Any extra help would be appreciated. Thank you
