Has anyone seen and/or solved the problem of the backlight flashing between it's setting (1 - 10) and it's max setting (10). Set does this for about 10 to 15 minutes then stops, seems to happen when scene goes from dark to light after having been dark for a short while. Does not appear to be heating related. I have ordered a set of capacitors to recap the (IP) power board.

I also changed the screen because the PC fell and the screen was broken.
I changed the battery with a new and original battery.

Hi everyone!
Hope you're all having a great day, and thank you very much for stopping by and taking the time to read this post to help me with my parents' Samsung TV.
My issue: No backlight.
Model: QE82Q70RAT
Type No: QE82Q70RAT
The TV was already serviced by Samsung once under warranty for the exact same issue, but six months after the fix, the backlight went out again. Now, Samsung is asking for nearly the same price as a brand new TV to fix this with the same 6-month guarantee.
So hopefully, I can fix this cheaper.
