    Lg 47le8500-za

    Hello
    I have bought a cheap lg led tv 2010 model. 47le8500-za
    With a defect mainboard. The previous owner wasn't fair.
    He did not tell me he had bake the mainboard.
    Problem now i need a other mainboard.
    The mainboard number is ebu60867152
    Does someone have a mainboard for a reasonable price.
    I will post some pictures.
    Thanx

    Try e-bay.com. If you can post pictures of the PSU and the connectors to the Main Bd. We could self test the PSU to see if it is really worth while replacing that Main Bd. Post clear focused close-up pictures of the back of the TV with the cover removed. If you can get this TV going it would be a nice TV to have.

        I have looked in e-bay-US and could not find a board like that. Well the Main Bd. is not working now so perhaps if you can get a Hot-air Station and heat the BGA chip for 10minutes at 350C, that might work. I have done this already with several LG Main Bds. and they seem to hold out, like 2 years already.

          This is a common problem with this model. First the HDMI chip fails and then the cpu due to bad BGA solder on the mainboard. That is the reason he baked it in the oven.
          The mainboards are on ebay but the price is way to high because they are usually not available.

          Are the components missing? If not try to heat up the board with a heatgun ( not a hairdryer ). Add some flux under the cpu and hope for the best......
          You need to remove the heatsink for that.
          I only repair Panasonic plasma tv's! Currently owning a TX-P55VT50 and still searching for a ZT60!

            No nothing missing but the bga leaked solder.
            I think it ain't gone work. Bga's have dropped down

              I don't understand the 'dropped down' means. You have nothing to lose Use the Hot-air station or heat gun and with flux at the sides if the BGA chip...heat it up and give it a try.

                  OK. I think it has lifted. The back part that is dropped down is how it is supposed to be seated.

                    The left side is normal. The right side has dropped down

                        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...

                        repairing 360 s6 vacume cleaner robot with stuck radar
                        by Matthieu vK
                        Hello,

                        I got my hands on a 2e hand 360 s6 vacuuming robot i wish to repair.

                        Unfortunately, a common (and mine) problem is that the radar, used for navigation is not working.
                        a second unfortunate thing is these problems seem to have many different causes, from dirty lens, to stuck hairs so it can't move, to broken down radar module to a faulty PWM (mosfet?).

                        the issue I am dealing with is what I believe to be a faulty PWM.
                        I have come to this conclusion as this seems to be an issue that others have dealt with also, but I have not found anyone...

                        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:
