    Hi,
    I have a 6 month old LG 50PZ570 plasma tv which a few months ago developed serious lip sync issues with my Yamaha RX-V350 amp. The lip sync issues are with both SKY HD (SD & HD channels) and my PS3 output both of which are connected by optical cables to the amp.
    I'm sure a LG firmware update has caused this issue but they say not.
    My amp has sound delay options up to 100ms but the delay is much bigger than this. Since my amp is quite a few years old now would a brand new amp provide a solution to my problem?

    Many thanks

    It’s difficult to say, especially as you think the problem is with the TV. Connecting everything to a newer receiver with HDMI could help, but you still need to use optical (or coaxial) to get 5.1 audio from the Sky+HD box.

    Have you tried adjusting the delay at the source, as opposed to the receiver? I know you can do this for the Sky+HD box at least, but not sure about the PS3.

    I don't think a new amp will help

    Certainly Sky hd box has ability to delay. Can the Yamaha not auto sync? My model does but not sure about yours

    Do you get the same length of delay on the sd channels?

    Are there any video processing modes on the TV that you could turn off? Sometimes these can compound lip sync issues. Is there an owners thread for your TV?

    My Yamaha does not auto sync.

    The delay seems to be the same for both HD and SD channels

    Thanks for your reply

    I went through the Sky delay of 0-200ms which makes a difference but the 200ms still isn't enough to cure the lip sync.

    Thanks for the reply

    There is an owners thread - thanks. I'll ask there about video processing modes.

    Cheers
