    Vizio D50u-D1 Mainboard 12v short to ground

    Hi,

    So the tv all of the sudden showed some vertical lines. I turned it off and on again and no picture, no backlight, only sound. It turns on and off by itself.

    I tried to do some diagnostices and traced down the problem all the way to the mainboard. There is no 12v present on tcon connector. One of the coil is shorted to the ground if I'm not wrong (0.011v in diode mode and 7.8 ohm)

    I don't know if it's just one of those caps next to the coil or something major.

      450watt power supply 5v, 3.3v short to ground wire,in output rail ,connectors
      by playit
      hello everyone , working zebronics power suply 450 watts , 5v ,3.3v givin short to ground black wire, also in circuit at output, resistor was charred but shows right values , after removing resistors 39ohms, 51 ohms, there was no short , no continuity beeps with ground , but after replacing new resistors (now i am not switching it on) ,again short still exists . when i put bigger ohm resistor like 100k ohm , no short beeping sound comes , lower ohm resistor gives continuity beeps ,other big ones donest , as its a working psu , i am confused what to remove now or how to go further now .

      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...

      820-00840 / No boot / PP3V3_G3H Short to ground
      by MisterAIL
      Hello everyone,

      Firstly sorry for my english, french guy inside.

      I brought a macbook pro A1708 - 820-00840 logic board, wasn't powering on.
      History is a day, nothing happened when opening the laptop.

      Nothing special inside, no corrosion, no liquid damage, never opened.

      First, with the logicboard alone on the desk, mesures are :
      5v017 and 0.000 amp. nothing else.
      Finding a short on the PP3V3_G3H_VR, but not on the PP3V3_G3H (0.540 on diode mode), PPDCIN_G3H_CHGR_R present (5,1 volts) PPVIN_G3H_P3V3G3H around 4.1 volts. PM_EN_P3V3_G3H...

      Bon soir dear online techies, enthusiasts, modest helpers and whomever I might have forgotten!

      Search gave me no hits so this is my first post.

      My Acer 5 Nitro mainboard had a short circuit when I tried to plugin a USB device. Some smoke rose from the port and it became super hot a that point of entry/exit. Warranty was of about a month.
      Since I am on a low budget I cannot afford to buy...

      Vizio P65 with P55 mainboard
      by maricm
      IH all, Got this vizio tv P65-E1 from FB marketplace hoping to be able to reflow mainboard as selerrstated that it was diagnosed with bad mainboard. However they must have tried to repair tv by putting another board in and they put P55 board in .
      Tv starts and responds to remote but screen does not look right , It looks like low resolution with some image ghosting. Now not having original board I dont know what to order ? Any advice how to figure out what exact board fits this tv ?
      And another question Would it be possible to adopt this board to this tiv by chagning eeprom or tcon...
