    Hitachi P50S601 ~ Green Vertical Lines throughout

    Hello all ~

    I was able to pick up a Hitachi P50S601 for free the other day and need some advice on how to proceed. I have already replaced the two 3300uf caps that were bulging (to nobody's surprise), and this brought to life the SDR-U board and a compromised top half of the picture appeared. However, the SDR-D appears to be defective because when that is plugged into the YSUS, the 3 blinking blue lights appear and no picture is displayed at all.

    The problem I am trying to solve at the moment (before plugging in a functioning SDR-D in and potentially damaging that too) is the fact that the top half of the picture is filled with green, very thin, vertical lines (hundreds of them) that essentially ruin the image. These vertical lines move in concert with the movements of images on the screen. For example, when watching an animated movie, the green lines will become brighter and will essentially follow the movements of the characters. This is especially pronounced when there is a brighter feature on the screen. For instance, when one of the animated character's white eyes move across the screen, these green vertical lines will become far more white and will move in unison from left to right and vice-versa with the character's eyes.

    Has anyone seen this type of greenish hue prominently affecting the screen, and what is the likely culprit?

    I have already tested it on both HDMI 1 and on Input 1 (where I hooked up the DVD player and started the animated movie), but the results are the same. I do not think the problem is port-related.

    Also, I am able to bring up the Menu with the Hitachi remote control, and these green vertical lines appear over the top of this menu.

    The sound works fine. No apparent problem there.

    I am curious what will happen when I go to replace the SDR-D board with one I can take out of a working Hitachi P50H401. However, if I can fix this green line issue on the top half first, I will be far more confident that I will not damage the working SDR-D board and will be able to piece together an entire working 50" screen.

    Please see pictures below.


    {Note: I know there appear to be horizontal lines as well as the vertical, but it is the vertical that actually move across the screen from left to right in concert with the images on the screen. I have already tried to unseat and reseat the ribbons that come out of the SDR-U into the set itself. This did not change the problem. When seated improperly, the small but distinguishable gaps between the green and black horizontal lines actually become grow a bit larger and therefore are much more pronounced than what you see in the pictures I have posted below. So, I don't know if the vertical and the horizontal line issues can or will be fixed with the same troubleshoot, or if fixing the vertical lines will not necessarily correct the horizontal issue as well. Just thought I would address the vertical first and foremost.}

    Some new info:

    I was able to test both the HDMI 2 port and the Front Panel HDMI port and the results have not changed.

    These green / greenish white vertical lines flood the screen and appear to "mirror" the images as they move across the screen. One more example:
    When credits roll after a movie, and they only take up the center 1/3 of the screen, then these vertical lines only appear on top of that 1/3. The left 1/3 and the right 1/3 remain essentially black. So, the plasma is definitely lighting up in relation to the corresponding digital signal.

    Does anyone know what is the likely cause?

      Samsung LA46A950 aka. LN46A950 - intermittent vertical green lines / distortions
      by 265chemic
      Hi All,

      I have a Samsung LA46A950 that intermittently was displaying issues with evenly spaced vertical green lines only on dark / black areas - this has progressed to more often and blue lines sometimes, as well as a little image distortion.

      My initial suspicion was the T-CON board, which I took out and cleaned but the issue persists. A heat gun on all of the control boards makes no noticeable change. Ive also reseated the T-CON to panel ribbons (4 of them) and moving them while the panel is on doesn't seem to change the issue.

      Below are some photos...

      by gpo23
      Hello,

      i order a t-con because i had bad colors on my SONY KDL-40V3000 :




      With the new t-con the color are good but there are vertical lines on all the screen :

      Samsung P2770H vertical green lines
      by wkx
      I have a Samsung P2770H monitor, on which I replaced the main board because it has an issue that it would restart itself every X minutes, that resolved that issue.

      Now, a few months later I turn the pc on and find 3 1px vertical green lines on the monitor, the lines wont show up on a screenshot. Does the same with dvi or hdmi.

      I opened it up and made sure the panel connection to the board wasn't loose and the flat cable looks ok. Pressing the connectors while the monitor is on sometimes changes the line colors from green to blue or yellow, but the lines are always...

      1/3rd of screen black with occasional vertical lines - repair attempt for learning! - Kogan KALED58RT9220SVA
      by Firentiosi
      Thanks for offering your assistance with this. I'm an electronics enthusiast with moderate level of competence (have a decent lab with two power supplies, microscope, DSO, hot air, good iron, can competently work at a component level on SMDs, design and solder own PCBs etc). I really enjoying fixing things and learning new stuff so took up a free 58" LED TV and have been googling and watching Youtube videos to see if I can fix this! I am happy to go down to individual component replacement/strip replacement etc - it's all in the name of learning.

      The issues are as follows: the...
