    Sharp LC-46D62U vertical lines

    Hi guys. I have a Sharp LCD tv with vertical lines. I suspect this is a TCON issue since I get lines through the menu when I press the menu button. Is this correct or could it be a main board or panel?

      first clean the LVDS connectors between main and Tcon board. Then the cables from Tcon to LCD. See if something changes.

              Disconnect one side of the tcon, check the picture then the same on the other side.

                  This is the main board issues. Try to reflow the two chips on the main board. Search the threads on this forum.

                      Here you go capleaker. The top pic is the screen with the right side TCON cable removed from the panel, bottom is the left side removed.

                          Budm provided the following pdf which may be of some help. Since the pattern is uniform I think it looks like that shown in Fig 4

                              Did you try heating (hair dryer) or cooling (can of air upside down) the Tcon and the main board while watching the screen?

                                  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...

                                  Colorful LCD Vertical Lines on Samsung ue55es8090
                                  by Falki
                                  Hello there, ive recently found an older 55inch Samsung SmartTV.
                                  Sadly it has vertical lines at the left and one line in the middle-right.

                                  I have already tested out the connections and have looked at the soldered ribbons of the LCD panel to see if some contacts got loose by pushing them a bit but with no success.
                                  I have factory resetted the TV as well but also with no luck.

                                  I am afraid that it is indeed a LCD Panel issue but there are NO scratches or any impact-marks..

                                  A similar issue has been posted as well but also with no actual response ...

                                  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
