lip sync-common problem??

collingwood · 28-04-2005, 11:05

i am a dealer in pansonic , bang and olufsen and other home av equipment. tech knowledge is average to good.

friend has a samsung PS42V4S 42 " Plasma linked to a Bose lifestyle system. i believe the bose is an LS28. The two are linked via a GP scart to composite video lead for picture.

he is getting massive lip sync, and seems unable to adjust. has tried swapping plasma for crt. works fine.

i have experience small amounts of lip sync before, but none to this extent (2-3 secs).

is there anyway around this?

any help would be much appreciated.

Not really unless you add a audio delay to match the processing delay of the plasma... a problem with them....... but it does seem a bit long!!!

Most times, switching channels away then back solves lip-synch.

Many STB do not lock teh Audio and vdieo together as well as they might and a Channel change resets the decoders and all is well for another few hours/ days

But devices like plasma take time to process the video so this also makes things worse!!!

(And otherwise the braodacsters are not as good as they might be !)

This happens to me with SkyDigital. If i turn the box off and then turn it back on, it's ok.
