Re: Samsung BN44-00284A Backlight problem
did check your transistors, easiest is the short test, see if any of the three pins test short to either of
the other 2 pins of the transistor.Comment

Re: Samsung BN44-00284A Backlight problem
did you have any pinkish hue off looking colors, you get that sometimes when a ccfl is on its way out.Comment

Re: Samsung BN44-00284A Backlight problem
so what happens when you unhook the cable from powerboard to mainboard and plug power cord in, do backlights come on and stay on?Comment

hello I have a backlight problem on this TV, if I unplug the cn201 cable the backlight works perfectly and the voltages are 13v if I connect the cn201 cable the backlight goes off and the voltage drops to 12v, I assume it's a motherboard problem, the question is has anyone had a similar problem? I want to understand if the motherboard is repairable or it's not worth wasting time... -

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.

Have a Samsung UE558000, which I thought was just going to be a straightforward backlight replacement, as the screen was dark in the middle.
After stripping it down, I noticed it was exactly the same lights out on both sides (see pic)
I tested the strips with LED tester, and no bulbs were out, so I tested the voltage going to the strips, both at the board side, and at the strip.
On Blue, there is 30.5v on pin 3 and 9, but nothing on the others.
Same situation on White, 30.5v pin 2 and pin 8
All caps look ok, anyone any idea?... -
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...
