LG E6 Screen Burn Issue

[sidewayslee]

Morning

Ive owned it 7 months, it gets regular use but nothing strenuous. LG have waved me out the door telling me its my fault, done all the cleaning cycles to no avail.

Anyone in here know an independent engineer I can maybe get a second opinion? LG have only seen photos and seem sure its my fault.

Any idea what has caused that? Did you have a static image on a long time?

Is that a news banner? Things to clear up early doors:
Cleaning cycles: you say they have run, do you mean the hour long panel clean that you select from the menu?
Standby: do you ever switch your tv off at the wall
ABL: I take it you didn't disable ABL from the service menu?
OLED light: what OLED light setting do you usually use?

I've seen on an AVS thread someone mention LG saying to them to put it into store mode for a bit and let the demos run, this has some quite dynamic content and pushes the brightness to the limits.

Is that an E6, not a G6?

I do watch both Sky Sports News and News but no more than I watch a film or regular TV, Line of Duty etc....

Hi,

Yes I did the hour long clean cycle.

Never switch off at the plug, always standby Im afraid.

Ive never heard of the ABL setting to be honest

Will try store mode later, fingers crossed.

Its def the G6, cost me £4500 in JL.

The settings I used are copied from the recommended ones found on here.
Am at work at the min so cant be precise, sorry.

Plenty of G6 pictures here, LG G6 (OLED65G6V) UHD 4K TV Review. The sound bar sticks out, yours looks more like my E6 where the sound bar doesn't stick out any further than the screen

That should rule out it being caused by a high OLED light setting then

What's AbL?

 

[sidewayslee]

Automatic Brightness Limiter - I had to look lol

 

[GadgetObsessed]

Have you contacted John Lewis? Your guarantee is with them not with

What's AbL?

Automatic Brightness Limiter. The brighter an OLED screen is the more power it uses. To limit the maximum power use the TV automatically dims when showing a very bright image.

The attached picture shows ABL in action. On the left is a 2016 LG OLED (like the G6) and on the right is a 2017 OLED. Because the image being displayed is predominantly a bright white screen the 2016 OLED's ABL has kicked in to reduce the panel brightness. The 2017 OLEDs also have ABL but it is less aggressive and kicks in less often.

LCDs do not require ABL as they use the same amount of power whether they are showing a black screen or a white one.

To add a bit of context, they are pictures taken after the still image has been on screen for a period of time. ABL detects the still image and reduces the brightness every few seconds. The 2017 panels reduce the brightness at a slower rate I believe.

ABL is supposed to stop burn in issues like the one here. You need to go back to LG (or JL) and say you haven't disabled any of the burn in prevention measures (ABL, screen shift) and don't push brightness to the max so they can't claim miss use.

I imagine you have either a defective panel or electronics that has meant ABL hasn't been working the way it should.

If JL or LG won't sort this out then get in touch with your credit card company. This shouldn't happen and you shouldn't be treated this way.

 

[sidewayslee]

Thank you for your help - I await JL's stance.

LG were frankly rude, it was very much a 'computer says no'

Not really pertinent to your issue, but that really does look like an e6 mate!

Anyway really hope you get it sorted, John Lewis have a good reputation for customer service so hopefully they can help? I too found lg pretty useless in the past. Good luck!

For this to be screen burn , you must be able to work out what the banner is. On my old plasma i got some burn , but always knew what the banner was.

 

[Rob20]

My Kuro has never had any issues with screen burn and I have left Sky Sports News on for hours at a time.

ABL doesn't just apply to still images - it applies to the brightness of any image irrespective of whether it is moving or not. It has to do this to keep control of peak power consumption.

ABL will kick in immediately if the image is bright enough - but it is true that it may become more aggressive after a period of time.

Here are the figures for how a C7 limits peak brightness from RTings:
HDR Real Scene Peak Brightness 600 cd/m2
HDR Peak 2% Window : 699 cd/m2
HDR Peak 10% Window : 681 cd/m2
HDR Peak 25% Window : 435 cd/m2
HDR Peak 50% Window : 240 cd/m2
HDR Peak 100% Window : 146 cd/m2
HDR Sustained 2% Window : 653 cd/m2
HDR Sustained 10% Window : 649 cd/m2
HDR Sustained 25% Window : 429 cd/m2
HDR Sustained 50% Window : 237 cd/m2
HDR Sustained 100% Window : 145 cd/m2

The tests above are done using a white square on a black background. As that white square gets larger the average level of brightness of the total screen goes up. On this LG it looks like ABL really kicks in somewhere between 10% and 25%.

I have also never heard of ABL being described as intended to reduce screen burn as it would not have much impact on screen burn. Screen burn is much more likely to be caused by small, bright areas of the screen remaining static such as a bright logo. Such a logo is unlikely to be affected by ABL as it is small. As can be seen above, this LG will happily display a bright white square that covered up to 10% of the screen at pretty much full brightness indefinitely.

LG's OLED do have other ways of attempting to reduce screen burn such as pixel orbiting.

In pretty sure ABL is there to protect burn in as it doesn't just apply to bright images.

I only really notice it when I pause something. The image will get darker and darker and then suddenly pop back to full brightness when you press play. ABL here is trying to vary what each pixel is doing (I.e. Avoid each pixel using the same brightness for a long period of time). I've never really noticed it when watching non-still images.

You're talking about ASBL I believe.

ASBL is the process whereby the panel will dim over time with static images on OLED tvs, ABL is as @GadgetObsessed described.

Do you know more about how this works?
I'm watching Sky news at the moment on an LCD (OLED is my next tv all being well) and several things occur to me.
The scrolling ticker is not static
The clock changes once a minute...obviously.
The currency box changes every few seconds.
There are several static elements too, but those three seem like prime candidates for ir, but are not truly static. Can it dim or blur those?

This thread is a bit concerning particularly given an active thread on AVS with several examples of ir/burn with a similar or identical cause.

Afraid not, only what people piece together on the internet. It's a little frustrating because I don't think LG even mention it in their documentation so it's all guess work.

On the EF950/EG960 I had previously, and my current E6:

• the TV could dim all of the screen when:
  • the entire image was static
  • enough of the screen was static (say for example, a podcast/discussion where there is a long shot from one static camera, and all the participants are sat behind a desk)
• portions of the screen dim or are gradually smudged out when:
  • There's a ticker, scoreboard or some other relatively static item with a relatively high contrast/sharp edges on screen

 

[Shocked]

There's another thread about screen burn.
I can say I'm an expert now - sadly. My replaced screen also shows some screen burn right now.

<a href="OLED Screen burn possible or not">OLED Screen burn possible or not</a>

My screen (55E6) was replaced last januari because of screen burn issue of a logo.
The "4" was visible in red/orange solid backgrounds. I didn't even caused it: when I'm not at home, my family watch a fair bit of the same broadcast everyday (RTL4). Not the whole day, but a few hours for certain.

Now my second screen is slowly also showing this "4" on solid orange/red backgrounds, again.

The technician told me screen burn was a very real problem and he replaced quite a few screens. I think the few reported here are just the tip of the iceberg, so to speak.

Also he stated: if you watch daily some hours broadcasting with a newsticker, static logo's etc., you better buy a normal led and not an oled tv.

- One thing I should mention: Because I'm carefully watching the screen burn issue on my E6, it seems the issue is a long time barely visible and the suddenly "jumps" a notch worse.
- screenburn is best seen on a orange/ red background (slide)
- it is a real issue when watching always the same program/logo/newsticker
- I don't understand reviewers comments about "burn" isn't an issue anymore on oleds.
- I now manual zoom the image so the logo is per week at a different location
- Despite the brilliant image, I'm thinking about selling it and replace it with a sony 55xe93 or so because this screen burn thing is worrisome and I can't control my family members on what they watch or how long.

Anyway, I think you should go to your retailer and demand a screen replacement. Good luck!

Thats no G6 its a E6

 

[Shocked]

Sharp, but as far as I know they use the same panel in G6/E6. Also screenburn isnot limited to one specific model, more reported on cheaper models like the E6 (more sold). Soc & firmware may differ a bit, but panel characteristics should compare.
