    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....

    Vizio E701i-A3 fixed but now has red vertical line
    by otaku_nut
    Hi all, I tried searching the site for answers but I'm a bit over my head understanding some of what might apply and what doesn't, so please be patient with me. I used Freakaftr8's fix to remove the left driver board to restore picture to a black screen with sound Vizio E701i-A3. After doing so, I now have a large red vertical stripe down the center of the screen. The fix did require getting another t-con board from online, I ordered it before I knew about the mosfit fix for the old t-con board. I have tried cleaning the cable connections to the t-con board. I swapped the cables going from...
