But they sent you the return label and are paying for shipping so they are responsible for any damanges and FedEx will ask the declared value of the tv

My panel is finally in and they're coming out Monday to replace mine.

What exactly do they need to do when they replace the panel? Is it the whole set minus the stand or is it just the screen so they unscrew the back end of my current TV and attach it to the new screen? The tech has me worried a bit because he had to warn me that the guy coming Monday has severe diabetes and is losing his sight. Not exactly the thing you want to hear about the guy coming to repair your TV! Also, he mentioned putting a cloth on a kitchen table for them to work on it and he mentioned putting the TV on the table screen down? Wouldn't that damage the screen on a 65" TV? These things are fragile.

I dunno maybe I'm getting worried for no reason.

TV: Sony A9G 77" Oled & LG B7A 65" Oled
AVR: Denon AVRX4300H
F/L: Emotiva Airmotiv T2, Center: Emotiva Airmotiv C2, Surround: Emotiva Airmotiv B1 x4, Atmos: Elac A4 x4, Subwoofer: PSA V1811, Actuator: Crowson x2

The only thing you should be worried about is whether or not the new panel will be better or worse

I got mine replaced last week and the guy laid the screen down on a table on some polystyrene and replaced the panel, using the plastic backing, circuit boards and speakers from my old one. The panels have protective plastic on the front and back that you can peel off.

They didn't put the back on properly on my new panel. After he'd gone I noticed a big gap at the top of the plastic back. I pushed it in until it clicked into place myself.

Sadly the vertical banding is improved, but I now have an ugly pink/brown/yellow (depending on background) stain/tinting left of centre

Then again I'm not sure that it can get worse than it is now.



What do you guys recommend? Here are some pics I took yesterday that really sealed the swap for me. Is this considered the bottom 10% of sets or is there much worse? Please note it wasn't even fully dark outside when I took these pics!!!!
Horrendous!

Last night the banding was evident in almost all content
This morning I spent an hour and half repackaging the unit and FedEx is coming.

LG support was inept as I tried to to that route. Better to see what happens with the exchanged unit IMO

Yeah my current panel has 2 very bad bands in the center and noticeable yellow/red tinting on the sides. I'll take tinting over banding any day. The banding annoys me very much. I'm definitely nervous. I watched the 3rd Harry Potter movie last night and didn't see a single band... I wish every movie I watched was like that! It was refreshing.

I think it depends on where the tinting is. I have yellow/blue tint across the top 3rd of the display. Noticeable in anything with a bright sky in it. I’d probably be happy if it was the bottom 3rd.

Seems as though most all recent reports of near-black-nonuniformity /banding/DSE are still related to 2017 WOLEDs. By this time last year, there was an avalanch of non-uniformity reports from 2017 WOLEDs.

Have there been many similar reports on the thread from 2018 WOLED owners?

My general sense just from scanning the last couple months of the thread is that LG appears to have made strides improving near-black uniformity on thr 2018 panels - am I wrong?

Seems like it. But what's the ratio of 2017 to 2018 new owners right now, seeing how the 2017s are in close out sales.

Check first post of this thread, all kinds of good links and info for uniformity testing there. Of course, you might not like what you find, and many recommend avoiding slides if you don't see problems in content. You can't "unsee" the flaws, and you'll be thinking about them instead of whatever show you're watching. Panel lottery is an annoying game with no guarantee the replacement won't be worse. But, some exchange until they get a good one and then are quite happy.

I can find many that are 5% gray (or grey) but I can't find one that has the "5%" notated in the lower left corner like others are using. A link would be appreciated.

Those are the slides in the first post. Download to USB thumb drive. Make sure TV is properly warmed up for 50 minutes, before taking photos though.

I would say don’t. If you can’t see the bands in normal content don’t go looking for it.

Thanks! I figured out MY issue. Wojtazo PSX's youtube video was the first one that came up for me as well when I previously searched. I was trying to see the "5%" notation in the left bottom corner on a Samsung LCD computer monitor initially without success. After you gave me the link, I decided to go to full screen and I had to look hard to see the "5%" in the corner because it was so dark. I plan to buy a LG C8 so I want to be prepared to check out screen uniformity.

Again, thanks!

Double-check the first post...I uploaded it to the cloud-based filesharing site, mega.nz: https://mega.nz/#!f4Ig2ASC!iu7UrrzLI...uJqDY47lz-xYcs (perhaps this needs placement nearer to the top of said first post for easier visibility; hint hint @VidPro ).

The first thing I did (before begging for help) was to check your 1st post of the thread. I saw the youtube video you posted but I couldn't make out the "5%" on my computer monitor because it was so dark. Upon further review, I finally saw it. BTW, very useful thread @VidPro started!

Well, I can't claim the glory for ALL of the first post, but I was happy to make contributions. You have to go below the Youtube videos where you can get your own copy (good for those times when you want to check a display without internet access).

Based on my untrained eyes, your E6 looks better than your 9500 & C7. However, your C8 looks the best.

^I should have mentioned that I dont have the ef or the e6 anymore...the e6 and c8 are close...that ef9500 was a nightmare, Lg replaced the panel, and the replacement was worse so they upgraded me to the e6.

Here is my 77c8 at 124 hours. This tv is getting replaced by lg because of hissing sound coming from power supply and the tech thought I’d could do better for uniformity. For the most part I do not see the issues very often. It does have brighter edges on the right and left that can show in a dark room. Mostly the lower right hand side. Also at higher apl it has a lighter band dead centre that shows when I’m gaming sometimes. Its taking a long time for lg to ship me a new one but I’m ok with that I just hope this next one it good. First picture in dark mode 35 oled light bt1886 gamma second is cinema oled light 50 gamma 2.2.

What a joke LG support is. This may be my last purchase of LG equipment.

Today was supposed to be my panel replacement. I already have gone through the song and dance of LG customer support for months. I sent them pictures clearly showing the issue and the panel swap was approved. However when the tech (the one I was warned about losing his eyesight due to diabetes) arrived he had me hook everything back up so he could run some tests on it. It seemed to be some slides that only go up to 10%. Also since it was via USB it was using different settings... it was in APS mode. I changed that to cinema at least but I didn't change the oled light so it was at 60-80 oled light which makes banding harder to see... not to mention the lights on and light pouring in the windows since it's 9am. Sure enough, he said he can't see any issue and loaded up LG via the support app on his phone. They couldn't see anything either because using a teleconferencing app on a phone is a joke for troubleshooting an banding issue. It can't pick up what you see in real life. I could still see the banding even in the horrible environment conditions but it was definitely less severe than seeing it in normal viewing conditions.

If you're in the market for a LG TV please be aware. This is the type of quality picture you will end up with because according to LG this is expected behavior! What a freaking joke.

Sorry to hear and went through a similar situation.

The television screen is the retina of the mind's eye.

It's why I spent half my Saturday repacking the TV for a vendor exchange.. I called LG and the level of incompetence was almost impossible to believe.



Not going to lie, Best Buy was FANTASTIC when I had issues with my previous LG 60. Prompt, on time, prepared and ready to help. I'm thinking of purchasing more items in the future from them directly and buying the warranty as the service they displayed was superior in every way.

So...what was the end-result? He just left? Did you try showing him content that shows the banding?

That sounds rough
