    Samsung UE32C6730 , Horizontal lines. Panel?

    Hey guys ,

    Found this tv in the trash. Panel looked ok from the outside so i thought ill take it home.
    Turned it on and saw these lines on the screen. Reseated all the cables but no visible changes.

    I think it is a bad panel. Removing 1 side of the tcon shows 1 half black screen , other side removed shows the whole screen with lines but less picture on 1 side.

    Anyone got any experience with these models? Dont think its bga on mainboard? It has a separate gpu though....


    Thanks.

          Capacitor C43 reads 0.8 ohm. Might be shorted capacitor that is causing the problem.
          Can i remove it? I read somewhere on this forum that people fix these problems with bad capacitors.

          Sorry , never repair these tv's haha.

              Sorry. That is a bad panel. Not T-CON Bd or Main Bd. Taking one side of T-CON Bd off gave both sides picture is a bit strange.

                  Hmm maybe not! Pressing on this small ic makes most lines go away.

                  Will try to resolder the part.

                      Does this Panel have Gate Tabs at the side?

                          No does not have gate tabs , was thinking the same by removing them on 1 side. I pressed the t-con at that area and the lines almost went away or got back at the whole screen. Im now 100% sure the t-con is the problem. Reflowing the resistors/caps did not help but it improved a little.

                          Will replace the t-con.

                              I found out via a local repair man that these mainboards are the issue. When you bend it a little the lines go away. I can confirm it.

                              Solution is replacement of the mainboard.

                                  Heat up the BGA chip with a Hot air Station if you have access to one 350C at fan speed 4 for 10 min.

                                      • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
                                      • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

                                      Samsung UE70TU7020K Which lines to tape on a bad panel

                                      Hello Community,

                                      I'm working on a Samsung UE70TU7020K.

                                      It looks like a bad panel. There is only 1 FPC cable from the Tcon (built into mainboard) to the panel.

                                      I'm using a piece of tap a few mils (covers about 8-10 pins), at different locations and have had varying results but nothing that is remotely watchable (multiple lines across all the screen, half screen and total black out on screen). The buffer board is divided into 3 boards. I've disconnected the end board one at a time but each time the screen was totally black. I presume it's because the potential...

                                      by x_orange90_x
                                      I just acquired this 3D LED yesterday and it has horizontal lines on a little more than half of the screen. When I first turn it on it has thin black lines going across that makes the image look serrated, and then shortly after patterns of thicker red lines fade in. If I turn it off and right back on it will reset to just the black lines and the red will again fade onto the screen.

                                      I initially thought tab bonds, but flexing the bezel makes no difference, and the fact the image sort of resets after cycling power is different. I haven't opened it up yet to actually test applying...
