If it's only happening with the HDMI connections, and not analog connections, that would likely indicate an issue with the TV.
But to answer your question, in many cases, receivers today have an audio delay. But if the audio is already delayed behind your picture, that may not necessarily be a fix.
Can you tell me what is connected, and which cables are used?
Hi. I've just bought a Samsung LED46B8000. The problem is that the audio seems to be a very slight fraction behind the picture. I don't have any external speaker set-up. I'm just using the internal speakers.
This happens whatever the source, whether it be broadcast digital TV or watching a Blu-ray via PS3. Is there a setting I can change, is this a fault with my tv set, or is this an issue with all the LEDs? Would using external sound remedy this?
