    Samsung LC32HG70QQUXEN - vertical and horizontal stripes across the screen

    Hi,

    Just now my Samsung LC32HG70QQUXEN monitor gave up on me. On cold boots I get many vertical stripes going across the screen (see the attached picture). After it runs for 1-2 minutes those go away but there are horizontal stripes going across the whole screen no matter of the input and PCs I use. (couldn't take an picture of it since the image size goes to 20MB and the camera doesn't pick them up)

    In a video about a 27" monitor with an similar issue the guy removes one resistor and supposedly the entire monitor goes back to life? For sure this fix is only temporary. Although I do not know if it applies to my fault.

    Comments on this video also suggest updating the FW to the korean one from Samsung (commenter has the LC32HG70 monitor and he said the korean FW fixed it).

    The vertical lines on my picture go away after setting Vsync to "best engine", but the horizontal are still there...

    There's so much info contradicting the video that I do not know anymore what to try. Any ideas?

    Found this article saying it is the resistors, but comments say it's not. So I gambled and desoldered that resistor.

    The vertical lines were fixed, but the horizontal? Nope.

    Those picture are pretty much how my lines look.

    Any ideas?

      Samsung UN46C8000XFXZA vertical bars/horizontal lines

      I posted about this previously but didn't get any response, and I have some troubleshooted a bit so I have more info.

      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...

      Hisense H55U7B vertical stripes
      by halen
      Hi all,

      I have Hisense H55U7B TV with no picture, only big vertical stripes. I did several tests and I'm not sure, where is problem.

      1. Connected tcon to 12V, white, red, green, blue, black picture visible in cycle on full LCD without error
      2. Connected only left side of LCD to tcon, big stripes
      3. Connected only right side of tcon, visible normal picture on the right. Working as expected.

      Where could be problem?

      Tcon RSAG7.820.7932/ROH
      Main board RSAG7.820.8698/ROH
