    Vizio M55-F0 Cannot be turned on

    I found this tv's situation is very complicated. It will take a long time for me to tell what I found. Therefore, if you don't mind, before I tell the complete story of what I found, I would like to ask some questions. Of course, if the complete story is needed, I will do so.

    The tv cannot be turned on. I found that the heat sink on the mainboard is so hot to touch even if it is just plugged into the wall outlet but without turning on the tv. Does this indicate that something wrong that needs to replace the mainboard or the other boards?

      Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
      by Tynan Dill
      I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

      Upon bringing it home and plugging it up, it showed a standby light.

      I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

      The screen seems to blackout and stay black, but with a flashlight I can see the display.

      With my Playstation 4 connected via HDMI, and running a game I can hear sound.

      Assuming...

      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...

      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...
