    Sony KDL46W4100 Vertical Lines

    I picked up this Sony KDL46W4100 very cheaply with the intent to fix it

    It has an issue with strange vertical lines on the screen (image and menus can still be viewed behind vertical lines)

    The past owner said he took it to sears and they said it needs a main PCB replace

    I just want to make sure other people agree that this is the problem so I don't dump more money into this without fixing it

    I have attached a picture

    What do you think?

      If the user interface appears above the vertical lines it is almost certainly a problem on the main board.

          Can you pull up the user menu, then take a better picture of it? From that picture, it is not easy to tell if the lines are affecting the OSD or not.

              Agree, if the user menu shows OK, then it can be the Main board.

                  Re: Sony KDL46W4100 Vertical Lines

                  I ordered a "new" main board

                  Same model TV, all same #'s on the two boards

                  When I put in the new board I get no picture at all

                  The backlight comes on and the remote and physical power button work... but no picture

                  I can swap in the old board and get the vertical line picture

                  But the new board gives me nothing.

                  WHAT DOES THIS MEAN? Is the new board more dead than the other? Or is it not the main board at all???

                      Re: Sony KDL46W4100 Vertical Lines

                      Just googled looks like serial # of the TV the two boards was from might be the issue. My # is 9111167 the other boards TV serial was 9015662

                          Help. Sony kd-65x85dj vertical lines
                          by visionbluedemon
                          First. it has no picture at all. i solved it by covering the ckv lines using tape to to block the connections

                          Second. now has picture but with vertical lines that follow the image. tcon board ic overheating

                          tried blocking LC lines too, but same results



                          is it lcd panel issue or tcon board issue?...

                          Sony KDL-40V3000 - Vertical lines
                          by gpo23
                          Hello,

                          i order a t-con because i had bad colors on my SONY KDL-40V3000 :




                          With the new t-con the color are good but there are vertical lines on all the screen :




                          I've tried the old t-con and it returned to the initial issue (bad colors but no vertical lines)

                          Is there a way to fix the vertical lines on the new t-con ?

                          Thank you for your help

                          Screen Display Vertical Multicolor Lines
                          by Stanley1843
                          Hello, I have a screen in where sometimes when I open it pop-up vertical multicolor lines (I would say the most of them are green). If I tun off and turn on the screen the lines dissapear or if I leave open the screen after approximately five minutes the lines gone. I measured the below voltages on the main PCB and on the T-CON board and the voltages are the same when it doesn’t display the vertical lines and when it displays the vertical lines. Also, I cleaned all the connectors very good with IPA. I moved back and forth the connectors and the COF tabs but the vertical lines didn't displayed...

                          Sony XBR-85X950G Gray horizontal lines and vertical picture shift diagnosis?
                          by noisykid
                          5.5 year old 85 inch Sony Bravia X950G started showing gray horizontal lines across the bottom of the screen and the picture shifts slightly vertically when it happens. The lines sometimes get bigger/smaller vertically and bounce back. See the video for the problem. It seems to be happening after it warms up after an hour or so. Happens regardless of source. Right now there's nothing but power cable connected and it's happening. We did hook up a new Nintendo Switch to our HDMI switching receiver today, and played for a while with no issues, but this problem didn't occur til a few hours later while...

                          Sony XBR-65X900H vertical lines
                          by dustman1747
                          I have acquired a Sony XBR-65X900H to try and fix. It probably was a complete no power situation. The main board was replaced and the TV started turning on. I now have start sounds and backlights, but no image. I've replaced the t-con with no improvement. Cables all appear to be ok and seated properly. The TV took a firmware update and hard reset but neither helped.

                          Using the tape trick I can get both side to display combinations of colored vertical lines. There is no change in the stripes and the pattern always appears the same. If I add additional tape strips I can get the screen...
