    Samsung UN55KS8000F Part ID please.

    I'm working on this 55" KS8000 that has the power cycle issue. I've managed to trace the fault to a component on the left most (when viewed from the back) buffer board.
    As per the pictures attached the component is marked 4263H and its silk screen number on the board is D005 so I assume its a diode array of some sort.
    My google-fu has failed me so I'm turning to the pros, would anyone be able to identify this part?
    Thanks.

      So does the TV power cycle if the cables between T-CON and the LCD panel are not connected?

          Yes, if any of the lvds cables are disconnected it will do the power cycle. I did trace the short down to that one component and removing it brought the tv back to life but i'm not sure if it can be causing any damage by not having that part there.

              Hello everyone.
              I also removed the exact same thing. Would there be any problem after removal?
              Originally there was 4263H, now I found 6514P 2015 (2019)
              I just don't know if it would be possible to replace it.
              Thank you for your response

                  Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
                  by Mgiffune
                  I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

                  I ordered a supposedly ‘new' Tcon board this time, and                  ...

                  Samsung ue55nu7021k Boot cycle
                  by Yoda79
                  Hi, wondering if anyone can help with a tv which seems to turn on but turn off soon after and continue to do this cycle over and over again.

                  It turns on, no sound and then turns off and starts the whole cycle again. I've opened up the back and can see the backlights turning on. However when I disconnect the two straps connecting the left hard board (as you look on the back of the TV), the boot cycle stops and it does turn on and I can hear the boot up sound, however no video?

                  Any thoughts, any help would be greatly appreciated.​...

                  Part identification for Samsung UN50F6300
                  by captainKKK
                  I need to replace the pictured small (3x2 mm?) Samsung LED strip component. I traced it the entire length of the first section of the strip. I assume it provides the positive voltage for the 2nd, shorter, plugged part of the strip. It's the one labeled 24V and scribed with 4E. AJ. Ideas for replacements, thank you.

                  Samsung WD80N645OOW died mid-cycle
                  by mrsith
                  Hi fellow lifesavers.

                  I have a Samsung washer-dryer WD80N645OOW which died mid-cycle. No response to anything, completely dead.

                  Checked the socket, the plug fuse, all good. Took it out to examine the boards.

                  There is a relay clicking on the mainboard. Upon applying power, I can see a diode flashing on inverter board, after a while a diode on main board lits up for a split second, then I can hear a relay clicking. This repeats a few times, then everything dies completely.

                  I've been trying to examine the main board, but it's a bit difficult becuse...
