    UE55D6200 black screen!

    Hello.
    I am French
    I have a SAMSUNG UE55D6200 identical to the UN55D6200
    In August 2022, the screen suddenly turned off
    The TV clicked at first but now nothing.
    I have searched many forums and looked for lots of info.
    By unplugging the Main, the LEDs did not light up.* So I changed the LEDs
    I bought 2 BN44-00457a power supply cards (1 on Ebay and the other on Ali).
    Same problem: still no leds lighting up
    I was provided with a BN44-00428a which can be installed on my TV but I do not have the same connectors
    for the leds, originally I have 2 wires per led strip so 4 wires
    on the bn44-00428a I have 2 connectors of 12 or 16 wires
    Same for Main:
    on the BN44-00428a there are 2x more wires than on the origin
    I know that my power supply board is compatible with the BN44-00424a

    Can I use the BN44-00428 for my TV and how to connect the cables?
    Thank you

    In order:
    BN44-00457a
    BN44-00424a
    BN44-00428A





    BN44-00428A

              For 5v resistors, for 12v a 12v lamp
              from my notes:
              TEST-PSU - Resistenze da usare: 5v/0,8A= 2x3ohm/2W serie; 5v/,9A=5,6ohm/5W; 5v/1A= 5ohm/5W; 5V/1,5A= 3,3ohm 10w; 5v/2A= 2x2,5ohm/5W parall; 12v/1,25A= lampad. 15w o 3x5w in parall.; 12v/1A= 4x3w parall.; (valori approssimati x brevi test)

              you have many choices, for each output around 1A is ok

                  Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
                  by Ryan.man
                  Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

                  My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

                  This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

                  iphone XS turns off when press on screen.
                  by smic717394
                  Hi,

                  I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on...

                  Samsung UE55JU6800K half screen dark
                  by Chrissygizmo
                  Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
                  I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same...

                  Vizio TV M50-C1 reboot cycle and static on screen
                  by spice_disc
                  I'm currently trying to diagnose and fix my Vizio TV (Model M50-C1). I've tried a number of different basic solutions, but I'm trying to determine if my issue is currently a failing panel, T-Con board, or main board (or something else entirely) and whether or not it is worth my time to fix it. Details of the issue and what I've tried are below as well as why I think it is either a bad panel, T-Con board, or main board.

                  The Issue: The TV will be on and working fine but after the TV is on for ~5-10 minutes the screen will freeze (with sound continuing) until the TV reboots itself. While...

                  ipad pro 9.7" blew a SMD component while replacing the screen 🤦‍♂️
                  by ipatch
                  i have an ipad pro 9.7" (1st gen) A1674 where i replaced the screen, but never attached the screen to the frame/chassis (glued down) due to the ipad being previously dropped so the new screen would never fit in the frame properly. so i need flex/bend the chassis to eventually fix the new screen in properly. so i temporarily just applied blue tape around the edges of the screen to keep it in place. when watching videos with the ipad the screen started flicker, so i though maybe the new quasi cheap amz screen i purchased was going out. so i disconnected then reconnected with power still on,...
