    Samsung ue48h6400 horizontal lines

    I've got horizontal thin black lines starting on the left hand side top quarter. The lines seem to disappear the further right they go and only seem to be on the darker colours.

    Any ideas of what could cause this?

    Thanks

        most horizontal lines belong to T-CON fault and LVDS connection, start with clean LVDS and reset them.

          Yeah, so clean the connections with isopropyl wipe? Just the cable or try to get in the block as well?

            Re: Samsung ue48h6400 horizontal lines

            Is there anything on the tcon board which might show signs of the fault being there?

              yes, clean LVDS from both side as well the socket of them at main board and T-CON as well

              very hard to tell what it caused this on T-CON if the cleaning didn't help. almost there parts on it got Value change. replace from known source would be ideal tips to try.

                  Put more lines on it... so try to reseated the cable again? Does it at least mean it's the cable?

                        Can I fiddle about with the cables while it's turned on to see if I can get lines to change without damaging anything.

                          not good idea... lvds cable between main board and t-con or t-con and pnel ribbon cable are contain many pin. any pin could remove aside will probably make damage.

                                photo in the middle No2 if the clean and reset LVDS from T-CON to MB or the ribbon cable from T-CON to the panel didn't help, replace T-CON

                                  Gave them all another clean nothing has changed same lines. Should I try the cable? Is it definitely the tcon? As the picture is perfect bar the line on the darker colours

                                    I've ordered a replacement tcon board. If that doesn't sort the issue what else could it be? Panel?

                                      No black horizontal line when there is a light coloured image. Would that discount panel?

                                        don't play any more with your tv. wait till your order arrived and check end result.

                                          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...

                                          Hello,

                                          First of all I'm new here. While looking I found this amazing forum and I'm very happy I did. Now for my problem:

                                          I picked up a Samsung UHD QLED QE50Q67TAU from 2021 for $50 knowing it was defective. The seller said it had black lines and that it could get stuck in boot randomly.

                                          I've tried a new power cable, hard reset, opening up and jiggling all cables, pressing everywhere to see if I get a reaction but I've gotten nothing. I've tried the tape method but I've only managed to get the lines worse.

                                          I'm no expert but I've done the tape...

                                          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...

                                          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...
