    55EC930V white vertical line appeared (need help)

    Dear All,

    I have 7yrs old LG OLED 55EC930v. One day a white line appeared on mid of the screen. 10mins later it was disappeared. When turned on tv again it was appeared again. Currently when power on tv is clicking sound relay, LG logo illuminates, 3 seconds later clicking sound relay and tv goes off. Screen is black during this on off period. When trying with service remote(pwr on) , clicking sound, white vertical line appears on screen(drawing line from up to down) and clicking sound then tv goes off. Please see video below.
    Please advice how to proceed and what is the problem?

    That's a problem with the panel or the t-con. The tv goes in a protection mode, that is why the tv shuts off.

      Thank you for your prompt reply. Here no one knows how to solve the problem, would you please advice any solution? Can I do something to understand the root cause is there a tutorial or instruction to check tcon or display?

        The panel is bad. There is nothing you can do to fix it.

        It’s seems to be a real common problem these days with panels shorting internally from shitty manufacturing.

          One thing I know is to block the protection pin on LVDS cable, tv could Start again but will not fix any screen issue (in this case a vertical line how you said.
          You have to look at the service manuel, when I remember the name was something like "burnt_det"

            Kogan - KALED65XU9220STB - Blue Vertical Line
            by TrueSword88
            Hi all.

            I have a Kogan 65' LCD Panel with a thin blue vertical line (top to bottom) on left hand side of panel.
            The line just happens to coincide with the end of COF and start of the next COF (attached).

            The line is permanent no matter what I've tried. I've tried pressure testing the panel (top to bottom) and all over, I didn't notice any difference with the line, either temporary or semi-permanent.

            Also tried unplugging all flex cables, cleaned with isopropyl then re-inserting to no avail - line remains.


            Hoping to fix...

            To fix laptop screen vertical line by working on its EDP cable
            by almarhum
            Has one here really gone through fixing laptop screen vertical line(s) by repairing/replacing its Embedded DisplayPort (EDP) cable, so would recount and share the complete steps of the process here now?

            As most, if not all, believe the laptop screen vertical line(s) caused by defective Embedded DisplayPort (EDP) cable which slipped and passed through either laptop screen hinge but post here is asking help to elaborate definitively the useful, real knowledge of repairing in the most complete, correct way, esp. can decide/determine whether the cable can still be fixed or must be re...

            Samsung QN65Q80AAFXZC QLED TV has a white vertical Bar
            by tech9pc
            Hi all Happy Holidays! Was just wondering if you think this white vertical bar would be fixable. Maybe bad TCon or ribbon cable? Contemplating trading a 50 inch Hisense 4K Roku for the Samsung but might get burned lol. The Samsung is model QN65Q80AAFXZC QLED TV has a white vertical Bar. Any thought appreciated. Thanks.

            Samsung UE58TU7100K - no picture, vertical line
            by mrsith
            Hi.

            Got UE58TU7100K with no picture - backlight comes on though. Figured out that's a perfect candidate for cut tape method.

            This model has just one LVDS tape coming off main board - and two panel boards underneath the LCD screen are connected to each other via small tape. Like curved screens. I've tried to disconnect half of the screen (5he side without LVDS connector on it, obviously), no joy.

            Disconnected the tape (main board side). Applied a small piece of tape, covering first ~4-5 pins. Powered the TV on - got picture. In negative, but that's...

            Partial Success Repairing Vertical White Bands on HP Z30i
            by lowteq
            Hello.

            I was given a HP Z30i LCD computer monitor that had several white wide vertical bands on it. I had another Z30i that was working and after a lot of swapping of components I found that the logic board, TCON board and associated ribbon cables were healthy. The problem was the ribbon cables that go from a long slender PCB across the top of the panel onto the panel itself. The problem connection was on the PCB side not the glass panel side. These ribbon cables are attached with some kind of heat set adhesive.

            I'm aware that this type of problem usually isn't repairable...
