I have tried a lot of masking, but nothing. This is already a replaced motherboard, I dropped the original and it was physically damaged. Do I need to do something else? For example, resolder one of the original chip or set something in the service menu?

I started a 4k hdr youtube video and I don't always see the error.
Horizontal stripes are only visible when the background color is dark. The darker the color, the more visible the stripe, if it is completely black, it is not visible. The quality can already be enjoyed from a few meters away. At the weekend I will try to mask again and assemble it, it will be good either way. Thank you for your help and your patience!Comment

Hi sorry to jump in but I've got a ue49ku6670xu main board BN94-11055E, the backlights were burned so replaced them , after doing so the new lights just flickered on and do a boot loop , I haven't got the screen back on yet as I was just trying out the lights before doing so, ive just tried another main board )totally different just tried it as the plugs fitted , just to Try checking the backlights, the board works the lights properly so I'm guessing it's my main board as I've tried a different power supply of the same model , I read in this thread something about jumper between FB_TRDV1 & FB_TRDV3 , could someone please explain this to me because I'm totally lostComment

Hi Team - just joined to see if anyone can offer some expertise in diagnosing an issue with a TV.
I've done a few hours googling and youtubing but just seeing if anyone has any insight here. I got a 55" Samsung UE55MU6470U which seems to boot loop and then after 10 mins will boot, work for a few minutes, then turn off and repeat.
Whilst it's on into the normal Samsung menu/boot screen it looks perfect - so I can't see there being any screen issues. I've seen lots of videos with taping across clock lines to diagnose which particular one may be an issue but i don't... -

Hi, I rescued a Samsung UN40H5003AF (H = 2014 FHD) from the curb. Symptoms are: standby (red) light comes on, stays on for 8 seconds, flickers off, then comes back on, and the cycle continues.

SMPS board: checked voltages, all seem normal (A13V = 12.8V, UD = 3.3V, PWM_BLU = 0.77V, PS_OnOff = 5.5V). Remove 10p cable to main board -> backlight comes on. I think this means SMPS board and backlight are good.

Hello all... TV started boot looping. Opened the back panel and tried to isolate the problem. Just PSB no boot loop. PSB and MB no boot loop. Plug in the LVDS from panel to MB and boot looping starts up. It doesnt matter of order that I plug the LVDS ribbons back in, only 1 and no boot loop but as soon as 2nd one plugs in boot looping. I then noticed a flicker on the screen when I was closing the clip on the harness to the LVDS. Shut the lights off so I can see better, and I noticed as i slowly close it, I will get a picture, but as soon as it clips in, I lose picture and booting happens. So I... -
