Hi all!
I've recently run into an issue with my Samsung UN55H8000AF LED TV displaying no image. I've done quite a bit of research in terms of what could be wrong with it. Below are the steps I've taken prior to reaching out here for some assistance:
1. I've tried replacing the T-Con board (BN95-01594A), twice and have still experienced the same issue with all the boards I've tested with.
2. I've tried to remove one side of the ribbon cable that goes from the T-Con board to the panel and still not getting any image on left or right side.
3. I've checked voltages on T-Con and all seem to be correct.
4. I've made sure backlight works, and it does function correctly.
5. Sounds check works, and logic board seems to be working since it's able to receive input from my remote and from the hardware buttons on the TV.
Some things I have noticed:
1. Blue LED3 on the T-Con board is very faint and flashes three times before completely turning off and staying off.
2. The blue LED below LED3 on T-Con board blinks once then stays on.
3. Backlight works perfectly fine and visible on all sides of the TV throughout the strip.
What I have yet to do:
1. Replace logic board/main board.
2. Replace power supply.
3. Replace panel (would hate to go this far).
Attached is an image indicating the LED3 on the T-Con board. I'll also post some links below to a slow-motion and normal speed video of the behaivor of the LED's on the T-Con. You'll notice the LED3 in the slow motion video turns on very faintly, flashes 3 times and shuts off.

Any assistance would be greatly appreciated, I would hate to have to throw this TV out.
Thank you so much!
