Hi. This TV has two LED strips. When everything is ok in terms of the LED and the power cable is connected, they both light up. In this case I found it strange that it didn't happen. I had to connect the infrared cable to make it turn on. A one strip of LEDs turned on and flashed 4 times on the infrared receiver. I immediately saw that there were more problems. I'll see if I can read the no-load voltage value and then divide it by the LEDs and find out its value. I hope you let me read the empty tension. -
God idea. Going to do that. ThanksLeave a comment:

Hi Diah. Thank you for your attention. Same Samsung TVs I've repaired: FHD, HD ready and now UHD, I don't remember finding one like this, melted along the led strip. In confidence, I put the new led strips, the same strip popped again. I'll go back to see the values and then I'll come back and give you news. This TV was repair in guarantee time, same problem. When it was repaired I don't know if they changed the board. ThanksLast edited by Ricksw; 01-15-2024, 02:50 PM.Leave a comment:

Sorry. You are correct. But on the screen this information appears. But I think the important thing will be the board's reference -
Anyone have the schematics? Thanks in advance...Leave a comment:
