    Hyundai PTV421

    Came in dead. Unusally power or other item that keep plasma "dead". Drumroll: microcrotroller is bust. No pulses on the EEPROM or any other pins and crystal is working.

    The mainboard is 2 layer sh!t and all of the components are on one side, none on the back, and not much traces as well. This thing needed a adapter board to interface with the power supply and the mainboard with bunch of capacitors and few inductors. What the heck. No BGA stuff, small yay. But not much in way of processing (no heatsink the chipsets at all), resulting in horrible youtube quality. Saw that at home depot 2 years ago.

    Too bad since this is nice LG panel.

    Cheers, Wizard

      Since it's a plasma you could probably make some $$$ selling it if the repair isn't too hard.

              LOL

              We are waiting for customer to say "final judgement" since this is your FYI on PTV421 and that particular part cannot be sourced, have to junk it or give it with regets to customer, yes we have 2 other panels needing power modules. Sigh, this what drives me nuts as this put me in limbo waiting.

              Oh yes, since this panel is fed by a LVDS, you can use a different mainboard hacked in as long as it is 1366x768.

                  even the panasonic plasmas i saw are alike, giving extremely crappy picture with sd sources...

                  it's fine if mfrs do that in country where hd is well present, but for european market they really should try harder...

                  as the things are going, i dunno will i be able to watch sd in any sort of quality by the time crts are no more...best thing would be to stash few more crts...

                      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:

                      QN65QN90A - Mainboard MLCC failed - now bootloop
                      by l0lhaxz1
                      Hi

                      I have a QN65QN90A which was purchased around launch I guess making it about 1.5-2 years old... had been working fine until a few days ago, simply went black and would no longer turn on (at all). No standby light and no typical PSU relay click etc. Absolutely dead.

                      Pulled it apart without doing much research first, suspecting the power supply as it had a faint buzz (I guess due to the forthcoming found short), investigated PSU for some time and concluded there was no fault that I could spot with the board removed.

                      Came to learn after a bit more research...
