    Help Me Choose the Right MAINBOARD

    It applies to Mainboard BN41-02751B-000 for Samsung UE70TU6905
    this is what is on stick : HU10 BN94-18627N P09R
    010233092557 0062 2021023
    1465.4-143/1010
    ​
    There are several part on Ebay for 55,65 and 70 TV but the number on the Stick label is not quite correct I am very unsure if they fit or even if they are somehow compatible with my unit. Very very grateful for any help

    any size with Odd Number 55-65-75 will not work on yours TV, Only the Even size. 50-58-60-70

      Such a number does not exist, maybe it’s BN94-16627N.

        Tank you Diah and you think there will not be any problem of computability with even ones? .This Mainboard i maybe should rework it but i do not find any datasheet for the chip :SDP19405 i do not know the size of the tin boll on it.
        it is the one you helped me in an other thread with the same TV number for 2or 3 days ago the owner want to try an other Mainboard but i will try to rework the old one anyhow.
        Thank you again Maestro

            the shit Sami. do it in this way Odd and even. Odd the most stable screen as they have double LVDS. the even one most all will be with one LVDS. any size will work if its not from original defect.

            i know its same TV. so i cant catch yours words rework.. i did explain before but if you still think BGA on SDA, i will say let fried it LOL.... cover all plastic socked with kitchen aluminum paper with out touching sockets self.. and backing your torte 10 minute ( no air flow function ) we don't want the torte dark brawn

              I have an IRDA T-862++SMD BGA REWORK STATION that can be used even if i am not very familiar with it i am training on other chip to learn using it. why there is no datasheet of that IC Chip?

                datasheet will not help as its one SoC.. see here the SoC and its contact pins .. you can ask seller to deliver chip stencil

                  thank you very much without datasheet or more information about it it will be quite creasy situation
                  then to find the right stencil for it wont be easy i will search on YouTube maybe i find some indications how to fix it but do you have an idea how much hot can i use to not destroy the chip
                  my IRDA T-862++ have 350 c degrees max .
                  I have already removed an SD from a broken circuit but it wasn't perfect because I think I used low heat on preheating only 160 degrees and 300 on infra red will try with some others to find the right temperature on the real chips

                    How to choose a substitute mainboard
                    by learnmore
                    Hello again Community

                    Anyone verse on how you go about choosing a substitute mainboard for your TV repair. Like the chap in the video below sometimes a 1:1 replacement board is too expensive and reballing a mainchip(s) maybe outside of your skillset . In the video the poster states one needs to match the replacement board with the SMPS, T-con (if not built in) and panel (and substitute cabling be also be required).

                    I'm very interested in choosing a suitable replacement board for any model or make of TV and the general (or detailed if your willing) step this entails....

                    Dell Latitude 7420 - Touchscreen not working since Mainboard replacement
                    by Mirenia
                    Hi everyone,

                    I've got a little "problem child": my Dell Latitude 7420 2-in-1, which had a faulty mainboard.
                    I replaced it, but ever since, the touchscreen no longer works — and honestly, I’m running out of ideas…

                    In Windows Device Manager, I just see an I2C HID Device with error code 10. Sporadically, the touchscreen is recognized correctly for just a few seconds, but I haven’t been able to determine under which circumstances this happens.

                    The touchscreen also doesn’t work in UEFI/BIOS, although it’s enabled...

                    MASTER TL240 and new mainboard LW36BKC01
                    by orcic
                    Hello,
                    I have an old MASTER TL-240 LED TV. Since it stopped working and it had a DVB-T receiver that is being dismissed in Italy, I've decided to replace the mainboard with a DVB-T2 one.
                    The original problem was that when switching on the TV, the power LED was transitioning from red to steady blue, without showing video or audio.
                    After checking some voltages on the power supply board (HKL-240101-B Rev. 1.4, HKL from now on) someone suggested me to replace the mainboard.
                    Now I have some doubts about how to connect the new mainboard to the old power supply.
                    First of...

                    Vizio M43-C1 - How closely do I need to match the mainboard number?
                    by Devonavar
                    I have a Vizio M43-C1 stuck in a reboot loop with no backlight.

                    I've tested all the voltage rails coming out of the power supply and they are "normal" for this model (PS_ON & DIM go high when turned on, BL_ON & 3D_ON are close to zero due to backlight power flowing through the mainboard, 5VSB is 5V, and 12V is 19V, which is apparently normal for this board).

                    Basically, I get similar results to Garry in this post: https://www.badcaps.net/forum/showthread.php?t=80346

                    So, I've ruled out the PSU for now.

                    The reboot loop...

                    Problem LG 49UB850V (Mainboard: EAX65684604 / EBT62954607)
                    by Malva
                    Hi everyone,
                    I'm trying to repair my LG 49UB850V TV (WebOS 1.0, UHD model from 2014).
                    Mainboard model: EAX65684604
                    PCB marking: EBT62954607
                    SPI chip: Winbond W25X20CLNIG Problem description:


                    Originally, the TV would turn on (backlight and LED OK if I force them on), but it shut down as soon as any input was received from the IR sensor or remote. The backlight and power board were working fine.

                    After testing and verifying the voltages (DRY ON, PWR ON, 12V/24V rails), I suspected a corrupted SPI firmware. What I tried so far:
