Bought my C9 65 from Amazon little over a month ago, but due to house reno's was not able to mount it till this week. Lasted for 3 days, and now fails to turn on. Pressing the power button on the remote makes the TV screen flash, a couple of internal click clicks, and nothing. It's trying to power on, but just decides that it can't and shuts off. Oddly the AVR will also power up with it, likely due to CEC still operating, but it also shuts off after 3-5 seconds when the TV fails to fire up. I've tried everything. Hard resets, cable removal, holding power for 30sec. It's cooked. Amazon return is out of the question because I am 2 weeks over the 30 days. Called LG, and they were pretty pleasant, however there is no option to have a new shiny TV sent out. It's a repair at this point. Local tech called. Still has not arrived onsite, but he already has a bad feeling about how this is going to go. Power supplies are on back order, so he has ordered a main board. He claims this is the most common issue, followed by the power supply. Fingers crossed it's the mainboard. If not then I will have to wait for god knows how long to have the power supply replaced. If that does not work, he says it will be the panel. I've read before that the panel is a pretty big deal in terms of shipping, and the local tech confirmed this. They ship a 65" panel on a skid from either Korea, Mexico, or the USA. The shipping crate is even bigger than what the TV comes in. No idea how long that will take to get. Feeling miserable about the whole thing, I sent a long letter to LG full of my tears, but that went nowhere. They replied with a standard cut and paste letter "We understand you are frustrated" its warranty and parts, bla bla.

One of the user reviews mentioned that the height ended up being either too high or too low... but am not sure exactly what the reviewer meant. He also had a 400x200 pattern, whereas the 65" C9 has a 300x200 pattern. (Link to the review)

Thank you in advance!
Sorry to bump but can anyone confirm a set of risers/legs, like the one I linked, that'll work with a 65" C9? Thank you!

I have a Denon 2112ci AVR that I've used to connect all my sources out to a single HDMI to my TV for 8-9 years. But I picked up the C9 this week and now I'm trying to figure out my next steps. I have a DirecTV DVR (non-4k compatible, is that necessary?), an Apple TV, a Blu Ray player, a Switch, and I suspect I'll have new Xbox on this one next fall.

The TV is wall hung with HDMI fished through conduit through the wall, but obviously I'd like to limit the number of sources connected directly to the TV to avoid a cable management nightmare.

I tried running ARC and HDMI-CEC on both sides but it appears the Denon's (at least of that vintage) don't cooperate. I think I'm satisfied to let my streaming services work through the TV rather than Apple TV but it seems like the C9's ability to control which source is selected on the AVR is critical.

Any advice on this? Avoiding buying a new AVR so soon after picking up the TV will help WAF greatly.

DTM I keep off.

Peak brightness should be on (by default) when watching HDR or Dolby Vision material. It's required for mapping HDR metadata correctly, or something like that.

Can't wait to get a few hundred hours in and have a calibration done.
Guess it's time to read this whole thread.

Awesome. I also just purchased a 55C9 and I am upgrading from a Sony 34XBR also! That I have had for about 17 years LOL. I know I am in the minority in this particular scenario so I was excited to see someone with a similar situation Kevmoso. After such an awesome CRT experience, I knew Oled was the only replacement option for me. So far I am very happy with it. The Sony has now been moved to the bedroom, as I can't bare to part with it.

I used to have one o' them thar 34XBR910's. Along with its younger sibling the 960, the best CRT TV ever made. About 8 or 9 years ago I got a 55" LG LHX, maybe the best LCD TV ever made (that's the one I'm replacing with this new 65" LG C9).

Had to get rid of that 200 lb. XBR monster though. So I gave it to my mother-in-law. When she also joined the LCD club a few years later, I finally had to get rid of it for good. None of the recycling centers would take it.

So I just left it out on the curb with a plastic sheet over it. Sure enough, somebody grabbed it up within a couple of days. So I fantasize that my ol' XBR910 lives on, continuing to this day to provide a great HDTV picture for somebody, somewhere, who probably has no idea what they've got. Other than it was free.

It's a personal preference.

DTM seems to brighten mid tones too much. But it does a good job at retaining highlight details.

Personally I do not use it and if I do dynamic tone mapping I use MadVR.

Keep it on if you prefer a brighter hdr image. All TV shows Movies etc... use high amounts of depth of field you won’t notice any loss of highlights if there’s any.

Yikes, that's the worst C9 I've ever seen, definitely completely unacceptable. Return or exchange it.

On that note you might as well keep it then and use it for the time being, post pics every now and then would be interesting to see if it gets better...

I ran Pixel Refresher and the panel is now pretty much perfect

I will post pics later today, but there is no discernible banding anymore even at 5%.

Great. Before you take more pics, please make sure you use the settings in the first post of the thread (when taking the pics). Your 5% looked way too bright. We need this so that we can compare different people's panels.

Does other LG 433mhz remotes work on the C9? I don’t really like the magic remote, too many wrong buttons to hit.

LG C9 ARC Issue w/Netflix 5.1

I just bought a 65" LG C9 but have an older Denon receiver (AVR-2113CI). I have ARC set up since I have all my HDR/4K devices hooked up to the TV. The ARC works fine for Youtube and Disney+, but Netflix I cannot get to work. The preview videos play fine (most of the time) but when I start playing a video I get audio that, the best way I can describe it, is the audio pulsating rapidly. When I switch the audio to stereo it works just fine. So it's specifically related to the Dolby 5.1. Does anyone know how to fix this issue without buying a new receiver? Additionally I have a Chromecast Ultra hooked up and the same thing happens when I use the Netflix app on that too.

I recently got the same TV, ARC'd to a Pioneer VSX-823 and also have the same problem...
Amazon Prime also doesn't work thru the TV, unless Bitstream Sound setting is changed..
I want to know if the supposed next firmware update is supposed to fix this specific issue..
Also, Does Optical pass the various 5.1 the receiver is capable of?

I can confirm I too have issues with Amazon Prime but for both Netflix and Prime if I select PCM as my audio source everything works fine (albeit in Stereo). When I set it to optical it plays 5.1 just fine.

Optical passes the same audio as ARC. Some devices will allow for lossy Atmos via optical but that's all, but both devices have to support that.

I never trust an atom, they make up everything.

I bumped the exposure on the first pic to make the pattern clear. I'll expose under same conditions for the new pics and make sure same settings are applied at export, but I can also supply a more authentic edit of the first image if it helps anyone.

All I can say is that pixel refresher drastically improved the situation.

How many pixel refresher cycles did you run on your 65C9 to get a significant improvement on the 5% grayscale image?
How does a 100% white screen look?

I did two cycles. The first ran for about 40 minutes before it was interrupted by my evil offspring.

I haven't done a 100% white check yet, but I did some movie screening, the same movies I watched with my C8, and could see no anomaly.

I will post pics later of 5% grey and 100% white.

Anyone mount their LG on a full motion articulating wall mount? I’m looking at great suggestions for my 77” C9... slim profile when retracted preferred.

I purchased the Kanto and Sanus ones from Costco, and while I’m sure they will get the job done their footprints are huge and they are very heavy..


Also for those using soundbars for your LG’s what type do you recommend? I have an open space design large kitchen connected to the living room where the LG would be mounted , so far I like what I heard at bestbuy magnolia on the Samsung HWS Q90 soundbar but I’m not sure at 500 or so watts this might be underpowered and whether better options are out there to go with our LG’s.

Thanks AVS friends

No it doesn't. Optical can do around 384kbps while ARC can do around 1Mbps. There is not enough bandwidth to do Dolby Digital Plus and Dolby Digital Plus with ATOMS over optical.

Any device that does allow it is exceeding the specifications of the optical port and cable.

I ordered a 77C9 on Nov 24 for a steal (recent Greentoe offering) and since then, every day of my life has been this:

https://chutzpah.typepad.com/.a/6a00...cfe4c52970b-pi

Well, I finally got word that it should be arriving on Monday and I am so excited!! I'm really really hoping to not have any panel issues as I really don't want to have to deal with repackaging and shipping back such a huge TV. I had to play the panel lottery a few times for my 5 year old Samsung plasma (which has been awesome) and I really don't want to go through that again.

I've been slogging my way through this thread (on page 130 at the moment!) and if you thought it was annoying to have to suffer through all the non-owner related tangents and light trolling over the months, imagine my plight while trying to execute a Matrix style knowledge dump while speed reading thru this thread!

At the moment, I just have one question... if I want to get up to ~100 hrs of usage quickly in order to evaluate the panel for glaring defects, would my best bet be to use something like the oldschool plasma burn-in slides and just run them for many hours while putting the TV to standby from time to time so if can perform its refresh cycles?

I am also super nervous about handling the 77C9 while installing on my wallmount... it looks so ridiculously fragile and I'm convinced I'm going to snap/warp the glass somehow
