    LG 42LH3000 - Half picture missing/distorted - AUO panel

    Just fixed this one with a friend. Nice 42" 1080p LCD. The fault was the left half of the picture was missing (black), or unstable (noisy, fuzzy etc) like in Norcal's video below:-

    Same "AUO" panel as that Sanyo, I think.

    We fixed the two outer tab bonds... and the results speak for themselves .

    In our case it was the bond on the PCB-tab interface that had failed. We found applying pressure to the IC did not affect it.

    This is our first truly big-screen tab bond repair that was successful. The Sony KDL-40W5000 was a disaster with a cracked panel being the result. Luckily, this TV was acquired for very little. The fix was stressful to do, but it all works .

      off topic: Did your sony 40" actually appear to respond to pressure on the side of the screen? I fixed a Sony KDL-40s5100?? i think it was, by running a small wire and resistor from a test point on the top to one of the tabs on the side, but mine didnt respond to any pressure on the tabs.
      Fixed so far 12 lcd's , 1 plasmas, 5 monitors, 0 dlp's (plan to keep the dlps at 0). and 3 atx power supplies, and 2 motherboards.

          Yeah, the 40" did. It used a Samsung panel. I think both defects exist with 40" Samsung panels.

              Missing LCD Panel Voltages VGH, VGL, VCOM (TCL 55P6US Sound & Backlight but NO Picture)
              by maneatingmonkey
              I have a TCL 55P6US with sound and backlight but no picture. This model does not have a T-CON board, and the right (rear perspective) panel board is fed from the left panel board. I have not been able to induce any change by disconnecting the secondary panel board or the tape cut-off method on the primary board.

              There are a bunch of voltages missing on the panel boards. I can't find any shorted caps of the panel boards, and all of the missing voltage rails read in the kiloohms, which leads me to suspect the issue may lie on the circuit board, rather than a short in the panel.

              VIZIO E70-E3 Half picture with half TCON
              by Fly_Among_Stars
              Hi,
              I have a VIZIO E70-E3.
              Symptoms: Black screen, no picture, but LED backlights are working.
              I probed the power board and voltages are as listed on the board.
              Main board appears fine, too.
              I believe the problem is either a bad T-CON board, or connection to LCD, or bad LCD.
              There are two separate ribbon cables feeding the LCD.
              If both are connected, the screen is black.

              If only the ribbon cable that feeds the right side of the screen (when viewed from the front) is disconnected, the left side of the screen shows picture and...

              SAMSUNG UN55KS9000F picture fades then distorts into vertical lines after 20 seconds
              by JJAAMM
              This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.

              Problem
              TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode...
