    Dell 2408wfp image sharpness worse over horizontal axis

    Dell 2408wfp, rescued from dumpster 2 years ago, Replaced logic board.

    Ever since then, I've had a hard time using this monitor, it felt like the image was blurry and out of focus, especially with text. Lately I've noticed that the problem seems to worsen over the horizontal axis of the screen.

    Looking for speculation or suggestions what this could be caused from.

      Check all capacitors on main and power board you may also have a bad T-con board
      dirty LVDS cable

          I fixed it!

          Honestly, not really sure what exactly the cause was..

          I took the unit apart, removed the TCON board, and re-soldered the LVDS connector on the TCON board. I also cleaned the connections for the LVDS connector and cable, and put it back together - Problem gone!

                  by Ihandyrepair
                  Hi guys

                  I just started fixing 4k TV few months ago. so I am still learning a lot
                  I got this tv from friend complaint is ghosting or horizontal lines on image.

                  never saw the original symptom but I took the tv back home. the funny part is that after bringing to home, the tv worked fine no issue for 3 weeks.
                  then it started to show the ghosting white image.
                  I started using the tape method, but this tv does not have a T con board and it has only 1 ribbon cable from main board to the tv panel.
                  it has 3 thin small boards at the bottom of the...

                  Samsung UE70TU7100 - flickering horizontal lines
                  by mrsith
                  Hello again good souls.

                  Got an UE70TU7100. The TV starts up just fine, but right hand side of the screen is horizontal striped a bit, and there are some flickering horizontal lines on the whole length of the screen. I've seen similar static horizontal lines sometimes, when applying the cut tape method and covering wrong number of pins.

                  I've cleaned every connector with ipa, tried cut tape method on main LVDS ribbon as well as small ribbons, connecting the panel boards at the bottom. Tried squeezing the bezel and playing around COFs, but no reaction at all. COFs and...

                  Physically bending the T-Con board creates horizontal dotted lines on OLED55CXPUA
                  by fredtred
                  Hello!
                  I have been trying to solve this issue the past 12 months to no avail. I have been a lurker here during that time but finally decided to post my problem and see if anybody knows a solution.

                  Problem
                  My tv (OLED55CXPUA) has an issue where it displays horizonal lines of dotted artifacts.

                  (See Attachment 1)

                  Self Diagnosing
                  After a very long troubleshooting period I traced the issue to the T-Con board. If I gently flexed/bend the board I could make the display go from GOOD to BAD and vice versa. I have ruled out the connectors/wires...

                  Samsung UN46C8000XFXZA vertical bars/horizontal lines
                  by x_orange90_x
                  I posted about this previously but didn't get any response, and I have some troubleshooted a bit so I have more info.

                  The screen is full of horizontal "gaps" or lines that distort the picture badly, and after about 10 seconds of powering it on the screen starts to fill with red vertical bars that take on the horizontal pattern. After the screen filled with the red bars, they instantly vanished and then slowly started to reappear. I initially thought it was tab bonding failure, but after getting down to them and pressing each one I find zero change in the picture. I went...
