    S642f lcd

    OK someone close selling this set, symptoms are a flickering screen.. Ownder states that the picture stays on but it is almost like the picture is shaking and strains your eyes.

    Whats the chances of it being the panel?

    If not the panel other possible causes?

    Thanks

    Re: S642f lcd

    Do you mean the image is flickering or the backlight? Makes a huge difference.

    From your description it sounds like the image in which case

    T-Con

    Panel

    Main A/V can't be ruled out!

      Is there any chance the panel could be bad and cause this though?

          I've seen Bush 42" with AUO panels which can fail in this way. But usually a repairable tab bond issue so...

              But how successful and how long will the repair last?

              OK if its for personal use taking the chance that it lasts but if selling on for profit would you really want that on your conscience? I know I wouldn't.

                I've had a tab bond repair last 6 months - Budm has ones I think in excess of 12 months.

                    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...

                    Fixing an I-Inc IF281D for the 3rd time, now with added flickering!
                    by DrvLikHell
                    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,...

                    Cutting the jumper on Samsung TV to solve the flickering
                    by Adenitz
                    Hello to all,
                    I have just seen this YT video about solving flickering issue on SAMSUNG TV. Reading many comments it seems this works.
                    But I wonder what is done here and how this solved the issue. I'm not able to find the schematics so cannot explain to myself.
                    Few years ago I had a flickering problem on one monitor in some factory which I managed to solve by inserting UPS between monitor and power outlet. I also notice on this occasion the flickering was gone if I put insulation tape on the power plug like shown in the attached picture to remove connection with the PE conductor...
