There is a slight delay in analog audio from my DLP TV, why?

Question

I am sending a digtal optical signal in 5.1 to a receiver and the TV's Left Right analog out to a different reciever. There is a delay with my new TV. There wasn't with my old TV. Any ideas as to why this is?

Can it be corrected?

Answer 1

Weird problem. The newer set seem to have a slow conversion rate for fiber optic to analog or it's processing the video much faster than your old TV.

The only way to sync it back together is to slow down the video so the analog audio can catch up. Run your video through another intermediate receiver or video switcher source before sending it to the TV.

I don't use the speakers built into my LCD. It kills the full room stereo effect. I go straight to my surround amplifier.

Answer 2

the digital audio simply moves faster than the analog audio, your optical signal is a light pulse moving at a significantly faster clip than the eletrical transfer of the rca cables. the way you described it seems like you dont have a cable or satellite box, but if you do you run the analog audio directly from the cable or satellite box  to the other receiver. that will keep the audio from having to be double processed.(box to tv then tv to receiver) this should eliminate the lag totally, but if not it should cut it down to the point where its almost unnoticeable. if you dont have a cable or satellite box there is nothing you can do about it. sorry
