    ue46c7700 white haze and vertical lines

    Hi
    I have a samsung ue46c7700 with a white haze on the left side en dark vertical lines right of the middle

    Before Im going to repair it, I just want to get some hints.
    Is this a panel fault or tcon. It also could be a dirty of broken lvds but I'm not so sure about the last
    My first impression is tcon because of the white haze but I'm not so sure


    With regards
    Anna

    If you did some research you would have a better idea. Seems like tab bonding fault to me, check for tab bond repair on here if that fails I would say the panel is toast sorry.

      Thanks for the quick reply

      Ofcourse i did some research. But the thing that made me doubt was the white haze on the left. I know the dark stripes could be a bonding fault, but how does that relate to the white haze on the left part.

      Could both problems be related to a bonding fault?

        Its ok, also remove the front frame for the screen and inspect the tab bond drivers and push on a few see if it has an effect. This looks like a driver fault or even something like water damage.

            Screen Display Vertical Multicolor Lines
            by Stanley1843
            Hello, I have a screen in where sometimes when I open it pop-up vertical multicolor lines (I would say the most of them are green). If I tun off and turn on the screen the lines dissapear or if I leave open the screen after approximately five minutes the lines gone. I measured the below voltages on the main PCB and on the T-CON board and the voltages are the same when it doesn’t display the vertical lines and when it displays the vertical lines. Also, I cleaned all the connectors very good with IPA. I moved back and forth the connectors and the COF tabs but the vertical lines didn't displayed...

            Vizio E70-E3 Two white vertical lines
            by brad2157
            I picked up a Vizio E70-E3 for free that shows Vizio logo and then goes to a black screen. Original owner said he started having wifi issues and then he tried to reset the TV and that's when it wouldn't boot up any longer after his reset attempt. I picked up a replacement main board from eBay that matches the same model # board as the original from the TV.

            Original main board - Shows Vizio logo when TV powers on, then goes to black screen. Doesn't boot up. No screen issues with any lines on start up Vizio logo.

            Replacement main board - Boots up fine, but starting...

            This "free from a friend who was going to recycle it" SONY BRAVIA XBR-55A8H arrived with the bottom center RED LED repeating a four flash pattern. It was treated with kid gloves and was reported to have "just gone dead" and the OLED panel has no dents in the metal frame or cracks.
