TV and Surround Sound system

cb102

hi there
I just bought a new smart TV, Panasonic TX-L42ET5B.
When I hook this up to my 10 year old Sony surround system (DAVS500), I have issues. (It's connected using a fibre optic cable.)

The issue is the surround sound is out of sync with the TV. Seems the TV is half a second faster. Very annoying. I've tried everything, well i thin I have.

Any ideas?
thanks in advance,
Chris

Some systems take care of lip sync but only if the same machine is handling both audio and video. It looks to me like you're feeding the satellite or cable box straight into the TV via HDMI and you're then running the audio out of the TV and into the old Sony system.

Because the Sony system isn't handling the video signal, it can't do lip sync for you. While the Video2 panel on the Sony can take analog as well as digital audio, there doesn't appear to be any analog audio output ports on the Panasonic so there's no simple solution.

One thing you could try is to use the AV1 SCART output on the TV. For this you'd need to buy a SCART to phono kit, this has a SCART socket at one end and at least six phono plugs at the other for left/right/video in and out (picture below). You would then connect the 'audio left out' and 'audio right out' phono plugs into the Video2 analog ports on the Sony and disconnect the optical cable. This should remove the digital to analog conversion delay and it may fix the problem.

No guarantee it will work but that's the only solution I can think of, neither the Sony or the Panasonic have A/V sync menu options.

Many thanks for the detailed reply. I'll give it a go.
