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.

Hello everyone,
Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
Anyway I still fully expect that there has been something seriously damaged... -
Symptom is dim backlight - this set came in with almost no backlight.
Samsung UN55JU6500FX2A
1 - Replaced all backlight LED strips (set had lots of hours at level 20 backlight)
2 - Changed out what appeared to be a bad Q9102C on BN44-00807E - not shorted or burned but appeared to be open. I was able to read (with difficulty) the part number - however I may have misread it - Can someone confirm that this is indeed an AOD9N40.
Backlight improved significantly - about like it would be set to a level 3 or 4. Setting all the way to 20 seems to...
