    Samsung un46c6300sf TV vertical discolored line

    I bought this TV used a few weeks ago and this vertical discolored line about 8 inches wide running the entire length from top to bottom on the screen. Sometimes it goes away but most of the time it is there. It distorts the picture of the 8 inch section and turns it a lighter color. I ripped the back of the TV off and checked connections and looked at the capacitors and they seem not to be bulging as some posts I read have suggested. Could it be something on the t con board? Or is it something on the power supply board? Or even the main board? I am kind of dead set on doing this myself, so going to a repairman is a worst case scenario. I saw refurbished boards on eBay for pretty dang cheap, but I want to make sure I'm buying the correct part before I commit. Thanks!

      Does it change if you flex the panel?

          Just tried that and it does nothing when I flex the panel. I uploaded another picture.

              Hmm, that is a strange one, never seen this kind of problem before.

                  The Mitsubishi LCD I had (used samsung parts) had a line just like that it was a bad IC in the tab bonded ribbon cable for the screen.

                  Only way to get at it is to completely tear it down to the screen and take off the metal shield and check the ribbon cable in that area with light pressure and see if to changes.

                      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 UN55KS9000F picture fades then distorts into vertical lines after 20 seconds
                      by JJAAMM
                      This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.

                      Problem
                      TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode...

                      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...
