I noticed a really bad lip sync issue watching The Deadly Game BR this evening, Panasonic 820 player connected to my 800 TV — player video to TV HDMI1, player HDMI audio to my Yamaha sound bar. I only noticed it in the closing scenes as one actor was speaking, so I’m not sure if it was because his lines were re-recorded or a BR disc or player fault, but it was really obvious. I still can’t get the colour balance right. The more I use this TV the more I dislike it, so I now plan to use it to replace my bedroom TV and I’ll replace the 800 in my front room with the LG TV that I was originally going to buy. The LG has better specs., HDR10+ support aside.
@bunyboy: I think that you need to contact JL and arrange for a replacement. It sounds like you have a duff unit. The troubleshooting that you’ve done is pretty exhaustive. There are a couple of things to try though: check that you have the latest firmware installed, do a factory reset, check how your cables are routed, use a mains suppressor. As I mentioned to
@Tzap above, I think that my 800 TV is picky about HDMI cables, so it might be worth trying a couple of new 4K-rated HDMI leads. That said, if your 28 return window is closing with JL, get it swapped out first as faulty. If you’ve missed the 28 return, then you’re looking at some sort of repair, but argue your case with JL.
