    Hitachi P50H401

    Hello. I just picked up a Hitachi P50H401 TV for next to nothing. When I turn it on, it has horizontal lines going across the screen, each about 1/8" wide. There are probably about 20 of them going across the screen. Picture is clear and sound is good. Only problem are these lines. Any suggestions from past experience what might be causing these lines?

    Any help would be greatly appreciated.
    Thanks
    Joe

    Common in these sets, you'll have to reseat all the connections going to the buffer boards. It happens a lot with this panel especially after replacing a buffer board. I'll bet the previous owner may have purchased a replacement buffer and after putting it all back, finds the horizontal lines, assumed a bad panel, and tossed it.

        I'm just learning here. So I would like for u to explain what does reseat all the connections mean?

            Those lines just about line up with the connector that needs to be reseated. Note which connector(s) need to be reseated then turn the power off and unlatch the connector and pull the ribbon cable out and push it back in perfectly straight and snap the clamp down. Turn the power back on and check the picture. You might have to do this many times. If there are no lines adjacent to a connector, DON'T TOUCH IT.

              TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
              by howardc64
              All left and right refers to looking from rear of TV (or looking from front with TV upside down)
              • 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

              Hitachi 58HK6100U - Horizontal Lines (Bottom third of the screen)
              by kdaniel
              As stated by the person I collected the TV from, it just stopped working overnight. However, I still gave it a go to try and repair it.

              There is a thread on the same TV but with slightly different issues where they had to tape connection points on the ribbon cable, so I want to see if this is repairable by any chance.

              After bringing it home and plugging it in, the TV turned on with its backlight working but had no picture. After removing the back cover, the first thing I tried is to unplug one of the ribbon cables and the situation is as follows.

              Samsung QN70Q6DTA Ghost or horizontal lines after tape fix horizontal line
              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...
