    LG TV 65ub950v with horizontal lines

    Hi everyone,
    For some time now my LG TV has had this defect. I turn it on and strange horizontal lines and video artifacts such as overlapping of parts of the image start to appear. The defect only occurs when it's cold, as soon as it heats up it works normally.

    I attach video

            So I guess it's the second option since when it heats up the defect disappears.

            However, as soon as I have some time I'll test it. Thank you​

              Hello, it seems we have occurred in the same defect at the same time ... did you test it and solve ? On my tv the defect appears for just few seconds when you power on or change channels, but if you need to operate on setting a large white rectangular area appears and you cant' operate ... The tv is a bit old (purchased in 2015) and I don't know if it's worth the effort of repairingK

                These are what I see when I try to open the settings and they disappear when I push the eject button on the remote. The last defect is when I change the channel and desappears after few seconds, otherwise the tv is perfect working

                      Ok,.i already gave to the OP of the most possibile solution, this is almost clearly a bga soldering defect of the main board, it is the cpu or ram chip, anyway you forgot the images uploading..

                        • 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.

                        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...

                        Sony XBR-65X750D Horizontal lines bottom of screen
                        by ggil44
                        Hi, I have a Sony XBR-65X750D that has horizontal lines at the bottom 6 inches of the screen. These lines appear to be every other line because the picture is still quite visible behind those lines. The lines appear all the time with a few other lines above and below the 6 inch level blinking on and off at about 2 second intervals. I'm not sure if this is a panel issue or power supply/main board problem. I did replace the T-Con board without any change in the problem. Any suggestions you might have would be greatly appreciated. Thanks,

                        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...

                        Samsung UN46C8000XFXZA Horizontal lines
                        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...
