    LG 32LN530B Picture Issues

    Hi everyone - new member here with an LG 32LN530B that's acting up. Last week I noticed a vertical line down the middle of the screen and the left side of the picture looked worse than the right. Still had sound and remote works. Over the course of an hour the picture gradually went away, to a gray screen with backlight and sound.

    Reading the trouble shooting guide, I thought that sounded like the tcon board. I ordered a replacement from shopjimmy.com and put it in. Now, when first powered on, the screen flashes with white/gray (line still in the middle) and then after about a minute I get a somewhat clear picture there is still a line down the middle and the left side of the screen still looks bad (see pic).

    I've tried different hdmi inputs and sources - no change. After reading through the trouble shooting guide here I'm wondering if the logic board isn't giving the tcon 5v but I'm hesitant to throw any more money at the tv. The tv is only 13 months old (one month out of warranty). Any suggestions on how to proceed? I don't know how to check voltages - but do have a multi-meter.

    Thanks!

    Ian

      Looks like the left side of the screen is scanning every other line, hence the difference in brightness. Could be tab bond or panel issue - replacing the tcon may have tussled ribbons enough to mess with the picture.

      Try running the panel with only one ribbon each plugged into the top of the tcon (I assume there is only two?) And report back your results.

          Thanks for the info, the tcon only has one ribbon (pic attached) and a cable connection on top. If I unplug either one of them I have no picture.

              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...

              Sony KD-75XF9005 grey Picture but Sound. TCON or panel?
              by iglitare
              Hi,

              i want to repair a Sony KD-75XF9005 TV that initially only showed a grey picture.
              Backlight seems to work, Sound (Setup menu after reset) works.
              If i dissconnect the left FFC cable from TCON to panel i have half a screen on the right. If left cable is connected always only the grey screen.
              Interchanged the cables, its always only the right side that is working. Always grey if left side is connected.
              With my small knowledge i would think at least the cables are good.

              Can this happen because of a bad tcon board?
              Or is it always a bad/shorted...

              LG 82UN8570AUD ~ TCON or PANEL?
              by kca
              Hello all ~

              Hope this finds you well. This LG 82UN8570AUD (April 2021 model) 4K UHD television has full audio capabilities but video is compromised / problematic.

              When I picked up this large LG tv it had a full black screen upon startup. Previous owner said it just went black one day. No popping sound or anything else of note.

              I got the display to work by taping off several traces of the right-hand side ribbon cable on the TCON that leads from TCON to PANEL. However, despite dozens and dozens of attempts to find the right combination / range of traces taped...

              LG 55sk8000 plb ..snow in the middle of screen but can see that picture exists there
              by burbutsalos
              Hello everyone.

              I have this TV set which has this issue. It shows a vertical bar im the middle of the screen.
              The panel has 12 cofs and the problem seems to be on the territory of the first cof on the right side.
              The tv fires up and you can see a good picture exept that vertical part where multicoloured pixels exist.
              The strange thing there is that you can see behind that snow that it shows picture but as if there are these pixels in front so you cannot see clearly.

              The effect is there even on a completely black screen.

              The screen...

              TCL 50S535 bad tcon or panel issue?
              by x_orange90_x
              Just bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side...
