Tech help required please....

Hello everyone,

I'm sure glad to find a newsgroup dedicated to home cinema as you're just the guys ' n ' gals who
can help me.

Now I have not exactly got what you might call a home cinema but my problem is simple. I have a
Denon AVR1802 which just runs a DVD player, PC sound and the TV (actually non-HD Sky+ Box) The sky
box is connected to the TV using the very old fashioned Scart which obviously gives sound and vision
which we view Sky TV. Sometimes, I want to have some decent sound so the 'audio out' from Sky Box,
is connected to the Denon....(we're getting near to the main problem now so please keep
reading).........Annoyingly, when I try to watch Sky using the scart's video output (TV sound turned
down) and the audio via the Denon.....guess what......the sound and picture are out of sync. Is it
the set up?...the leads? Just for the record, I'm sure the sound is before the picture. I've just
checked the 'AUDIO' setting from within Sky box and it just says 'STEREO' for audio out. There is an
option to use OPTICAL CABLE (which I have got) to give Dolby.

FYI - The audio lead I'm using looks a bit nicer than the average 'red and white RCA' cable. It's
black and has a blue ring around one plug and a red one around the other...is this the correct lead?

To avoid setting up all the amp parameters of the surround sound (ie distance from rears, and
centres etc) I have it just on plain old 'STEREO' setting. This way, on this occasion, it takes any
'delay problems' out of the equation.

Any ideas? Maybe it's actually NOT possible to be in sync - but at least I'll know.

I'm sure that when I first set it up years ago, it was fine. Over the years, I've changed leads,
settings and TV and now it seems this problem is apparent.


Best wishes (see if you can help me get it sorted for Chrimby...)

*****NB***** JUST BEFORE I POSTED THIS, I DID SOME GOOGLING**************

I think I may have answered my own question. Am I using COMPONENT RCA cables as my 'audio out'?
Should I just get a bog standard red&white RCA??

Many modern TVs have processing for the video which delays it. They have a
built in delay for the sound to bring it back into sync. Plug any external
box into the TV - both sound and vision - and it will keep them in sync.
Use the TV vision only - with the sound fed to an external amp and
speakers - no sound delay as provided by the set. So they are now out of
sync.

Many modern AV amps have a facility to delay the sound too. HDMI input
types will often do this automatically.

OK - Thanks for your rapid response.

I've had a play with the setting and, yes, changing the delay time on the front speakers has
improved things a little (I didn't realise I could change the fronts - DUH!). It is very difficult
to get it just right and what makes it equally annoying is that when I set it up for one channel (eg
Sky News) it is out of sync by a different degree on another channel.

I've been adjusting the delay time in this way..........With the TV and external speakers sound on,
I've been changing the delay time to get the minimal
'echo' effect. Then, I think, the sound should be pretty close to what the TV is kicking out. But it
is very difficult!!!

***The audio cable I am using - will that make any difference? Should I change it to a standard 'RED
& WHITE RCA'????***

If you go on BBC HD it shows a syncing tool a few times a day.
