Panasonic UB820/UB9000 4K UHD Blu-ray player

[Geoff D]

I have none of my players connected to the internet and my 820 has been good as gold. (If only the same could be said of its actual performance, the issues with Dobly are just plain embarrassing.)

Yes please and report back if you are able to.

That was my thought for no connecting to the internet this time.

Mine has been connected as well.

Has anyone tried playing a xvYCC Sony 'Mastered in 4K' blu ray on the UB820 with a non-Sony 4K TV? Im playing Elysium 'Mastered in 4K' 1080p blu ray on my LG OLED BX and it looks good.

Well.. I did a factory reset of my Panny player (this time didn’t even connected to internet) and wow.. no issues anymore with that disc, apparently. I watched the problematic sequences three times and no pixelation or sync problems. Why would that be? Does this make any sense?

I had a different issue, but it was also solved by a factory reset.

Whenever I left a disc in the machine (which is often as I usually fall asleep mid movie and either wake up and finish it then, or the next night), it would always give me a disc read error when I turned it on and tried to play it again without ejecting first. If I ejected the disc, it always played no problem, but never if I left it in and tried to play it. Weird issue, but was happy the reset solved it.

Even on a Sony TV the Mi4K thing was nothing but a marketing wheeze anyway

I’ve checked it even a fourth time later and still clean playback in those sequences. So weird.

I wonder what kind of glitch can cause a player to develop playback issues like pixellation or out of sync audio with very few specific discs (or movies), that a factory reset solves it.

Java data can sometimes cause that. It sends the player mixed messages and player doesn't know what to decode.

Clear BD data first if you have an issue. If that doesn't work then factory reset.

Don't connect your player to the internet. it will cause glitches. I never have any problems with discs and I leave it off and only connect to check for a firmware update. I use a streaming box to stream stuff. Turn the wifi off though when playing a disc and only turn on wifi to connect to a network or stream but leave it off for just disc playback.

When I had the ub820 connected to wifi, cloudy with a chance of meatballs 3d/2d refused to play. Tried it for at least five times with the same results. I disconnect the wifi and it works flawlessly everytime. I keep it disconnected till l check for a firmware update, which is never.

I have had this player since November. Got the modded version to get it regionfree. I really like it but I have noticed a few things that seem a bit strange.
So I watched the 4K release of Zombie from Blue Underground recently and noticed some very noticeable "flickering". The flickering was consistant and occured throughout the film. This was also the case on To sleep with anger released by Criterion. Anyone else experienced this? I have an OLED CX.

Thanks.

Sounds like near black flicker (overshoot), which is an OLED issue.

Ok, but it seems strange that it has only occured on a few discs. Is there anything I can do to fix it?

What error message did you get? or what happened when you pressed play?

I have been asked to help a friend select his first 4K disc player. He only wants to spend about $500. His TV is the Vizio OLED55-H1. With his budget, is the Panasonic UB 820 the best choice despite these reported Dolby Vision issues?

No error. Just wouldn't load.

It happens more regularly on lower quality source material and SDR primarily,, and it can be masked with a little bit of ambient light in the room...so it's not a surprise you don't always see it.

The best way to mask it is ambient lighting, or if you want to lower Black level a click or two but that's at the expense of crushing some black.

My UB9000 came with Firmware 1.64. The available firmware in the US is 1.60 from Panasonic website. I know a lot of owners are updating to 1.66 Firmware for China Region. Is there any advantage to upgrade to 1.66 Firmware?

It's probably more tv dependent than player dependent, but if you have another UHD player (such as a Sony) might be worth trying to see if it happens on that too.
