So I picked up a beautiful ST60 a month or two ago and have been breaking it in gently and finally getting to see the beauty of a higher end plasma panel.
But what I have noticed is a lip sync audio issue where when watching a movie the sync seems to go off after about the half way point and it becomes really obvious for a scene or two then suddenly seems to go back in sync at some later point.
I started searching online and found that Panasonic had done a specific firmware upgrade to address the sync issue. I already knew about the big input lag on this model but since I don't plan to game on it I didn't think it would be an issue. However to my dismay when I pulled up the firmware page it appears my TV has the latest firmware already installed on it.
I've been using my PS3 for BD playback through my Onkyo TX-nr626 receiver via HDMI. I believe I was using HDMI input 1. I've never had to use any offset values as I'm usually running into an HDCRT for my display and using external speakers which has no audio sync issues whatsoever. I'm still using the same receiver and external speakers and if I switch back to the HDCRT there are no sync issues at all.
If I switch over to HDMI2 with the ARC could that solve my problem?
So far this is killing my enthusiasm for an otherwise fantastic unit. i have every additional feature disabled including all motion smoothing and this isn't connected to any online functionality. I used the DNice recommended settings and am only using this for Blu-ray playback via HDMI.
