I believe some people said they couldn't tell any difference with quick start on or off. I also wouldn't hold my breath for another firmware update at this point, we'll be two model years out very shortly.

There is probably no surer sign of an impending firmware release than the strange predictable re-expressing that there most likely won't be any...

I'm pretty sure we've been here before...It's deja vu all over again:

https://www.avsforum.com/forum/40-ol...l#post57123512

Pretty sure there has been a release since early-November, the last one being mid-December.

They are definitely not developing the firmware any further what with the lack of engineering server releases - don't let your eyes deceive you, clearly that's not a newer firmware version:

There must be some sort of weird LG TV firmware FUD cult - probably made up of the same folks that insisted there were/are/wouldn't be no Windows XP updates past April 2014 (5 years ago)...guess I'll have to remove all 317 XP updates provided monthly since then.

Now, if only I could just as easily remove/rollback 6 years worth of firmware updates from my 55LM8600 (or from any LG TV for that matter)...

There will be firmware updates but I doubt we can look forward to any major new features/changes on this set.

My C7 just hit 4,000 hours last night, and it subsequently ran a second round of pixel refreshing. No issues, and the calibration looks just as good as always. Flesh tones are so good that you don't notice. If anything, it has a little more SDR pop.

Turning on Match Framerate in the Apple TV settings screws up HDR10 stuff in the Amazon app, or at least it does with The Grand Tour. When the setting is on, colors lose saturation. Not sure if this is an Apple TV bug or a LG bug. I'll try testing on my Roku later.

How do you know if the pixel refresher runs? I'm at 5948hrs and I don't recall anything happening.

I think my firmware was updated to 05.80.15 (I have auto update turned off, so I'm not sure how that happened) and I am suddenly experiencing ARC issues when using native apps. Until yesterday I had sound from the my 65C to my Onkyo TX-RZ710 with no issues whatsoever. Atmos worked perfectly as well. If I used the TV remote it would adjust the sound on the receiver. Now, I get no sound at all and I get a the circle / when I attempt to adjust sound. I tried scanning the thread for this issue but I can't find anything. Is this a known issue?

Anyone ever notice a fairly strong horizontal band? I have what appears to be a line running across the top part of the TV, about where the screen starts when watching a widescreen 4K Blu Ray. It runs from one side of the panel all the way to the other side.

Have never noticed it until recently and it was a bit annoying. Could see it clearly in near black scenes and with other colors as camera's pan.

Disconnect any other devices connected to the Onkyo and remove the power from the Onkyo and LG. Then plug them back in and turn them on. This should get ARC working again. Then connect your other devices.

I have had similar issues to this on iTunes movies running in hdr with March frame rate set to off. This behavior started happening with the last Apple TV beta update for me.

Unfortunately it sounds like you have got the dreaded burn in. What may have happened is the part of the screen that is showing the picture when watching a widescreen BluRay has worn a bit more than the black bar bit which is obviously inactive as it's not emmiting any light.
To try and cure it you could run pixel refresh a few times and if no joy get in touch with LG support even if you are out of warranty. You may get lucky and they just might replace the panel for you.
Good luck.

So I ran the manual pixel refresh for the first time on the panel and now the entire screen has horizontal and vertical jailbars. Looks like a call to LG is in order.

What upsets me most is that I've watched around 20 Blu Ray movies in just under a year on the set and I can't imagine that would be enough to create burn in

Lets hope LG get this sorted for you without too much hassle or delay.

Strange.


I tested Die Hard in the Vudu app (only HDR10 movie I have) and it wasn't affected by the framerate setting.

Your ON/ON look more natural to me, the Off/On make Hammond look like he has sun burn.

Well, the sunburn pic is how it's supposed to look and how it looks on the internal app.

My C7 briefly displayed a message saying that it was going to do a "Pixel Refresh" while the unit was turned off/on standby. The next morning, it displayed a message that said "Pixel Refresh Complete". So, it's entirely possible that the pixel refresh function took place while the TV was turned off/on standby, and you might not notice the messages as they don't stay up on the screen for very long.

I don't believe there is a way to turn off this feature, so I'm fairly confident that your set received the proper treatment.

Audio Dropouts problem

Hi guys.

I have the old audio dropouts problems and it's driving me crazy.

Here is my setup:

55B7 OLED TV
Ruark Audio MR1 MKII Stereo speakers (connected via Toslink)
Vodafone TV Box (Connected via HDMI)

I have random audio dropouts (0.5-1sec) on TV Box and Netflix and I don't know how to solve this. I tried disabling HDMI CEC changing audio to PCM and the issue still occurs.

Can anyone help me with this issue?


Thank you in advance.

I belive the last movie we had this issue with was transformers revenge of the fallen, which is a DV title. We have had it show up serval times before on HDR10 and DV titles only. The issues we have had have also come with somewhat different symptoms associated (purple hue, dulled color or brightness level)
It’s not consistent enough to make it happen when you want like the Amazon app with GT as described. It comes and goes randomly, but stays once it has started.
Matching frame rate fixes the issue and totally avoids its return.

After the last time it decided to do this I took a look in the ATV video setting to see what if anything was changed and sure enough match frame rate was off. I turned it back on and resumed the movie and all was correct again and has been since.
I’m not sure if it’s an ATV firmware or LG old firmware thing...I suppose it could even be a combination of them both interacting oddly with one another since they both last updated around the same time.

I’ve never really seen anyone talk about it, so I never bothered to make a post over it. I chalked it up to some weird bug or a hardware issue starting to show on my end.

Mine did the same thing and LG told me to get lost. I sent in photos and an engineer replied that it's normal and won't be covered (I live in Canada). My panel was OK out of the box - not the best for banding, but not the worst either. I ran a manual pixel refresh to see if it would clear up and I ended up with both horizontal and vertical "grid lines" of banding across the display. Many hours later, it's subdued quite a bit but still visible both on 5% grey test patterns, real content, and 100% color slides (R/G/B).

Wow. That is disconcerting. My 65 has been about as good as you can get until I noticed that top horizontal band. Was it perfect? Far from it. The manual pixel refresh really bunked it.

I tried to setup a ticket with LG and they are beyond incompetent. First, I can't even submit a claim online as it says "model is a swap unit". I proceeded to call the call center, probably located in Kathmandu and they gave the phone number to two "authorized" LG technicians. One went straight to a cellular VM and the other told me he was too busy to talk and that if I called him in a week or two he may be able to help me.

I can already tell this is going to be a nightmare. I live in the heart of Miami, FL and I'm shocked that LG has no real coverage here.


I haven't been able to look at the banding today but I suspect all content will have visible banding as the pixel refresh tool took a relatively clean TV and gave it horizontal and vertical bars that run across the entire TV, side to side.

What do you guys suggest I do in terms of contacting the inept idiots at LG?

Shocking, given that LG's Central American/Caribbean/Southern USA regional service office is located in Miami, as well as over a dozen authorized service centers nearby. You are so screwed.

I tried to setup a ticket with LG and they are beyond incompetent. First, I can even submit a claim online as it says "model is a swap unit". I proceeded to call the call center, probably located in Kathmandu and they gave the phone number to two "authorized" LG technicians. One went straight to a cellular VM and the other told me he was too busy to talk and that if I called him in a week or two he may be able to help me.

I can already tell this is going to be a nightmare. I live in the heart of Miami, FL and I'm shocked that LG has no real coverage here.

Maybe give them a phone call instead of using the online service?

I know.. Crazy thing is that I'm not sure it's even banding. It's a relatively low usage living room TV... Probably logged less than 20 4K Blu Rays and less than 30 letterbox movies... I measured the horizontal band line and it's in the identical spot where the black bars at the top of the TV end.. Panel has less than 900 hours with no network TV outside of the occasional football game.. I don't even have cable. It almost seems like burn in.. Not sure what to do now.

I will say that IR on this set is almost instantaneous. One or two minutes browsing Youtube and you can see temporary IR on other screens. I wonder if there is a link between accelerated banding/ burn in and TV sets that have quick IR.

I did. Online service wouldn't accept the claim because of the aforementioned "model is a swap unit" error message. The LG call center said I had to deal with the two "local service providers", both of whom seemed like dudes that don't even know what the word banding means.

Now, I get no sound at all and I get a the circle / when I attempt to adjust sound. I tried scanning the thread for this issue but I can't find anything. Is this a known issue?

Negative Ghost Rider. That was the first thing I did. I also seem to have lost Simplink control of other devices. My LG remote used to control the volume of the receiver, as well as work with my FireTV cube and it does not do either of those things. Is it possible the update changed the minimum HDMI standard and my cable no longer supports it?

Contact LG and let them know the response you get/got. I’d give the 1st one at least a day to call back however. I’m not sure how you can determine that from leaving a VM however.
