    I read on the Hitachi thread that some get this prob. Some thing to do with the time it takes for a plasma or lcd to produce the picture meaning that the dialogue or sound is a frame ahead.

    Do all plasmas suffer from this problem? seems to happen alot with sky.

    Most plasma and LCD screens will sufer Lip Sync problems to a certain extent due to the extra processing required...Sky suffers from Lip Sync problems at the best of times and it just shows up more on plasma/LCD...also some people seem to suffer more than others as I'm sure someone will pop in and say 'Ive never seen it on my XXX'

    Cheers, Lee

    Yep ! Not a problem on my Hitachi 42PD5300 :smashin:

    Yeah, sure everybody gets lip-sync probs occasionally with a Sky/Freeview box, but that's a fault with the encoding process, not the TV.

    Nice one Nik :smashin:

    Yet you'd think the Hitachi, and other ALiS panels, had the potential to be the worst offenders as don't they deinterlace a source, then scale it and then re-interlace it before displaying the final image ?

    Cheers, Lee

    A lot depends on the speed of the chips used in the signal processing. Cheaper plasmas tend to save on costs by using slower chips. Just as in PC's, faster chips cost more. :smashin:

    The New Sony TVs have a lip sync adjustment- so if, say Sky is a few mS late you can compensate. There is a preset for each AV input.

    has anyone noticed faint black vertical lines on the screen when watching TV? the lines are roughly spaced apart by 2 centimetres.
    they are much more visible when a football match is on for example.- a screen image of a constant colour.
    i find these faint very annoying and am wondering if theres something wrong with my screen. - i bought the TV last week,,, :(

    cheers

    Trouble is that when Sky lip-sync problems do occur, they do tend to vary in timing.

    Agree with Nick, some channels are better than others, but there are several add on boxes that can correct this if you have digital audio out.
