    Vizio D39H-CO no display or sound

    Hi, I have a vizio d39h-co led tv with working backlights but no picture or menu. I have replaced the mainboard twice, changed Eprom, changed lvds cable. This tv has only one mainboard with power supply built on the mainboard. I checked voltages at tcon which is built on the panel all look good. The board # is AMtran 3639 0182 0150(7b)
    PLEASE HELP

      If you check the LVDS with an oscilloscope (while flicking the menu on and off all the time), it will tell you if you are getting a signal to the t-con. After that, it is replacing the T-Con, which you can't... so at the end of the day, this thing is toast, unless you repair that board.

              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...

              Samsung UE60KU6079 backlight okay mainboard responsive, no picture, no sound
              by Ierwin
              Hello everyone,
              Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
              The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
              He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
              I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
              Anyway I still fully expect that there has been something seriously damaged...

              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...

              Vizio M65-E0 No Picture, No Sound
              by ggil44
              Hi I inherited a Vizio M65-E0 that isn't working. It must have been dropped on the corner because I found that the infrared circuit had a capacitor with one end broken off of the board and some green corrosion around the plug to the main board. I re-soldered the capacitor and cleaned the corrosion well and tried turning the M65-E0 on and I was successful. My problem is that while the back lights come on and appear to perform local dimming there is no picture or sound. It kind of looks like you are looking at the TV through a very dense fog, where changing the input on the remote will change bright...
