    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...

    Samsung LC32HG70QQUXEN - vertical and horizontal stripes across the screen
    by kotel studios
    Hi,

    Just now my Samsung LC32HG70QQUXEN monitor gave up on me. On cold boots I get many vertical stripes going across the screen (see the attached picture). After it runs for 1-2 minutes those go away but there are horizontal stripes going across the whole screen no matter of the input and PCs I use. (couldn't take an picture of it since the image size goes to 20MB and the camera doesn't pick them up)

    In a video about a 27" monitor with an similar issue the guy removes one resistor and supposedly the entire monitor goes back to life? For sure this fix is only temporary....

    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...
