    Samsung LA46S81B LCD Problem

    I have this issue with my LCD TV. The bottom part of the screen colour is a bit off from the rest. And the refresh on that part seems to be slower and thus I get ghosty image. (kindly refer to the attached photo)

    Is this likely to be an easily fixable problem?

    Appreciate guidance from whomever knows the likely cause of this problem.

    Thank you very much

    Reminds me of the old problem of the tab bond connections not getting good contact any more, sometimes can be "fixed" with a shim or maybe tape. Some videos on youtube with this type of "fix".

      Here's an example, notice how a little pressure clears up the picture, if that does not clear up the picture then the tab bonds are probably ok, you could start by making sure the flat cables from tcon to panel driver boards are clean and not damaged, can clean with isopropyl alcohol, some use a pencil eraser, not to hard they can be delicate: https://www.youtube.com/watch?v=vCExlSnG4yY

          Samsung UN55JU650DF network/streaming problem
          by howardc64
          Fixed a 9 year old UN55JU650 by replacing backlight. Original backlight LED was still working after 27k! hours but terrible picture of course. Few LEDs were out, 5-6 lens fell off (bright white spots) and another few popped off with slightest force. Surviving LEDs were all slightly blue so picture has a blue tint.
