    Vertical black bars

    Hello,

    Posting this question for a friend. I can not seem to find too much info about solid vertical black bars. Is this a panel failure?

    It is a Panasonic Viera plasma.

      I had 2 panasonics with this problem. A 50" I fixed by cleaning with alcohol the ribbon connector on the lower buffer and the second that had a bad panel. I even tried a new buffer but made no difference.

          I was afraid that it may be a bad panel indication. From what I have read is that the vertical lines are a bad panel and the ribbon cables are not soldered to the panels. If it was horizontal lines then that can repaired. I have not had a chance to look yet and I could buy it for around $50 but I don't think I want to take a chance.

          Thank you

              I might still buy it for $50 because some of the sc boards to these panasonics can be sold for over $100. Obviously all the boards are working with the possible exception of the lower buffer c board that corresponds to that line.

              You could still make money. At least here in Columbus the parts are worth more than a working tv.

                      Buffer boards only fix the horizontal lines or sparkles etc. Vertical bars is most of the time a panel failure but it can also be dust/bad connection.

                      I had a 50" , think was a 50G20 with same issue. Reseating the cables fixed it.

                          Hi,
                          Can you somebody help me to solve a problem with my Panasonic plasma TV?
                          The model is TH-37PV80PA. When I switch on the TV on the screen are visible three wide black vertical lines. I open the TV and unplug the flexible connectors situated on lower side of the screen (just below the black bars) and switch on the TV again. The black bars become white.
                          My question is: Is it mean that the problem are the two buffer boards below the screen or the problem is the screen itself?
                          If someone can give me some sugestions I will be very happy!
                          Thank you in advance!

                              Vizio M65Q7-H1 Red Vertical Strips fixed by tape blocking LC1 signal to half of the panel

                              Failure Symptom



                              No picture, just red vertical stripes. Google search shows quite common problem for these recent Vizio M series although red vertical stripe pattern may differ. Some call it "Netflix" boot screen haha.

                              Where is the short?

                              Panel has 4x buffer boards. Quickly found the 1/4 panel buffer board with the problem by selectively disconnecting buffer board flex cables.



                              Having recently fixed another Vizio with similar symptoms that was a shorted ESD diode array ( link ) Probed the ESD diode array but...

                              Sharp LC-70LE650U vertical black and red bars

                              Hi all,

                              70" LED TV is Sharp LC-70LE650U.

                              Initial problem was horizontal lines and slow motion lurrs on the bottom left of the screen. So I removed both the left and right ribbon cables from the T-con board and tried to clean it with alcohol and when I put it back, this issue appeared. I tried carefully reinserting the ribbon bon cables but same thing. I checked the traces of the ribbon cables with magnifying glass and everything looks good. I cleaned the small jumper ribbon cable on the left side of the screen which cured the horizontal line and slow motion blurs...

                              TCL 50S535 bad tcon or panel issue?
                              by x_orange90_x
                              Just bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side...

                              SAMSUNG PLASMA TV PS51E550D 1W shorted BDXXX on board
                              by LanTHrusteR
                              SAMSUNG TV PS51E550D 1W,
                              Symptoms: the panel is on but no picture, fuzzy color vertical lines at the black background at both sides of the panel. Very similar to this:


                              Disconnecting left side of the panel fixed the right side which went on and displayed picture although with vertical black bars coming from the middle X-BUFFER panel at the bottom of TV and the same 1 fuzzy color vertical line ~ 0.11 inches long and a few 1 pixel black bars. The disconnected left side showed fuzzy colorful bars, may be some glimpses of the the correct image from menu at the right side...

                              Samsung 55" UN55JS9000 - Pink vertical lines due to chipped LCD panel?
                              by Anonmis
                              Hello all, I was recently repairing my Samsung 55" UN55JS9000 tv from the common burnt backlight LED's and cracked light guide panel issue. After replacing the LED's and putting the TV back together, I tested the tv and all I was getting was sound but no image. Somewhere along the way (could be related to the next issue) the T-Con board became damaged and after replacing it I have made a little bit of progress but now have bright pink vertical lines and still no image.

                              The bigger issue .... I took the TV apart again and realized that I likely didn't sit the LCD panel correctly...
