    Flickering and double/ triple images

    Hi,

    My samsung 32 inch LCD TV has suddenly developed this problem - flickering and double/triple images of moving objects. When the scene changes, there are frozen images from the previous scene. I have tried removing the ariel and connecting with my laptop through HDMI but same problem.

    Could anyone pls advise? The TV is abt 3 years old.

    Thanks

    What is the model #? Does the TV have a 100Hz feature? Or is it vanilla 50Hz?

        Just 50Hz (which is fine, given most 100Hz sets look awful.)
        Can you provide a picture of the fault?

          It sounds like tab bonding, wait to see the pictures to confirm.

            Sorry for late response. Actually, the problem used to occur few minutes after turning on the TV. For last two evenings, the prob is not occuring so cdn't take pictures.

                  I can't tell but in those pictures is very faint vertical line and everything underneath that line is flickering like vertically jumping but everything above it is perfect?

                    There is no vertical line. however, there is a permanent horizontal line about a centimeter from the bottom edge.

                    The problem occurs after the TV is switched on for 5 minutes. Some weird magenta coloured horizontal/vertical lines start appearing from the left side and then ghost images.

                          Looks like a tab bond/panel failure

                          Different fault possibly same cause/fix

                            Agreed. You could push on the tabs to see if the picture normalizes if you feel comfortable doing it.
                            Did I leave the soldering iron on?

                              I tried doing that yesterday but no change. Is it something which is repairable at a decent cost so that it works for a reasonable time.

                                Ok. Do you have freeze spray. Spray on both sides of the lcd panel right at the line thats one cm from the bottom. see if picture clears up. I had an off brand TV with samsung internals that I modified the screen and it cleared the problem. But this modification is not for the faint at heart.
                                Did I leave the soldering iron on?

                                  And if the freeze spray method does not work try heat at the same areas. Not too much that it melts anything thou.

                                    ACER BM320 Monitor - Horizonal Flickering Lines After a While
                                    by reessi
                                    Hello,

                                    The monitor started off showing flickering thin (1 pixel) lines horizontally every say 3mm..

                                    They are black on the right and gradually fade to nothing on the far left.
                                    They start either after 5 mins or up to 2 hours after so annoying for testing.
                                    They flicker continuously very fast! With a slight pause milli-second every second.

                                    Initially I cleaned the LVDS cable and connected to the T-Con and then it worked fine for 3 weeks but not sure if this was just co-incidence.

                                    I tested each half by removing the first the left flex from...

                                    Hello everybody! It's been nine years and I'm back again with the same monitor that several people here helped me fix back then. The first time, I replaced two caps as was recommended here and the original problem was solved. Then it started acting up a few years later and I came back for a parts list and replaced a few more caps (I didn't make a post about that and don't remember which ones), and again the problem was solved. This time, however, I'm not sure if it's caps.

                                    The monitor stays on but certain colors will flicker. Generally it's darker colors like dark greys or dark blues,...

                                    LCD displays a 2nd image slighty offset vertically. And multiple pairs of black lines along the bottom. Probably common as google "TCL 49S405 double image" pulls up this ifixit post ( link ) with identical ( nearly, but their fault seems to be on the other half of the panel than mine ) problem without solution.

                                    This one looks to be a more difficult to diagnose because most? of TCON seems integrated ( CSOT BGA on buffer baord) into the left panel edge board ( looking from rear of TV) There are 2 buffer boards for each 1/2 of the screen. Main connects to the left buffer board...
