I have a 2012 Panasonic P55VT50 plasma TV and was horrified the other day to see image retention or possibly image burn on my TV.

The solid colour 3 news logo has firmly taken hold on my display. I'm trying my best to remove it.

I watch 3 news most nights along with 3 hours or so of other content.

Does anyone know of a WMC plugin or other app that I can use to blur out the 3 news logo so it doesn't get worse?

Regards Allen.

How long after the show was this taken?

It won't be permanent burn, just image persistence.

It's still there the next day even after watching several hours of other content after the news every night. So each night I watch 3 news it just refreshes it. I hope it hasn't gone beyond image retention to irreversible image burn.

I changed the saturation curve on the photo to more clearly show it. The untouched image is below.

I am running THX Bright room with contrast 55 and brightness 0. Vivid colour is off, Pixel orbiter is on auto.
I ran the scrolling bar for a couple of hours and it seemed to help but not eliminate the image. I'll run it overnight ans see what happens.

If I can't find a way to blur out the logo I could zoom to push it off the screen. Not the ideal solution.

The Three news logo is the only one causing this because it is a solid colour logo.

I'm going to write to Media works to bring this to their attention. I can't believe I'm the only one with this problem?

Regards Allen.

I was worried that was going to happen on our samsung plasma as we watch 3 news every night but it hasn't thankfully

3 news should fix this!

I'm going to zoom the news so the logo is off screen. (unless I can find that logo blurring plugin for WMC). Anyone wish to write one?

You aren't.

I have a 60" GT50 and have some experience with this particular problem.
First up, the bad news. This is going to last a considerable amount of time. The good news, its not permanent.

I put over 750 hours on mine before I noticed the 'ONENEWS' logo as a dark shadow against the white of my Xbox 360 dashboard.
I did all of the usual tricks to try and remove it, but it wasn't going anywhere. I changed to watching 3 news, but after a month, it two had left its scar (this time on the bottom left of the screen). I then made the decision to cease watching either broadcast (not that difficult really) I kept a close eye on the affected area and it took four months for the One News logo to completely vanish. Over that period, neither logo touched the screen.

As a gamer, I found it strange that I never experienced any long-term IR with any of the games that have graced the TV. Some of which have had persistent, solid white HUD graphics just like the TV station logos. I'd also play games for several hours at times over several weeks and yet the news broadcasts are only an hour and punctuated by ad breaks. The fundamental difference is that the 6pm news was always the first thing on and the gaming was almost always done later after the TV had been on for a couple of hours. It seems that with these particular models, that initial startup period is when the phosphors are given their most voltage, which means that anything solid white and persistent, is going to leave a mark.

I've gotten into the habit now of running the scrolling bar for 15-20 mins when the TV first starts up. The jury is still out on whether its a solution, but I've not seen any significant IR in several months.

These are still superb TVs despite this problem. IR behaviour can change though, so there is no way of knowing where we will be after 5000 hours until we get there.
What probably won't change is the station watermarks (well its not technically a watermark if its opaque!) I see banners getting more and more intrusive and spammy with disruptive animations, so I don't think the networks really care about their logos being an intrusion. IMHO, they are just giving us more reason to migrate our viewing elsewhere.

Ive sent a complaint to media works. That will probably fall on deaf ears. Im still really impressed with this tv. Best blacks in any tv released that year. I'm going to zoom media centre to zoom 2 to push the 3 news logo off screen. I just need to figure out how to do shift ctl z on my harmony remote. I can do single characters with the media centre keyboard device added to the remotes devices but not key combinations. I don't have an actual IR media centre keyboard to learn the command from.

4 hours of the scrolling bar it's reduced significantly but it's still visible on a white background.

So there's hope it'll eventually dissappear completely if I can keep the logo off the screen.

You'll be fighting a losing battle thinking Media Works will do anything. Even if you managed to get them to do something you've then got every other network to deal with.

My Pioneer Plasma (2006 model which is the last of the "older" generation Plasma's that do suffer permanent screen burn rather than just temporary image retention which you're seeing) is an absolute mess with TV3, Sky News and CNN logos permanently burnt into it. This is very obvious if you have a full white background but is not visible during normal viewing.

You really need to understand it is only temporary, and more importantly why it actually happens. The same sort of thing will happen on any new LCD TV as well (but will disappear quicker) but ironically thing will get worse in the future, OLED displays suffer even first screen burn than earlier generation plasma panels.

Yes not alone I have the exact same set as you, its great, but yes have similar issues with image retention, I usually have issues with the wife playing MTV all day and warriors games with the score board getting burnt in, but that passed quickly. Prior to this set I had a top of the line Samsung plasma and it didn't have the same issue.

Depends. My sister-in-laws plasma has a nice big Sky mute logo on the top left. Looks it's there to stay . Mind you it's her own fault. Turns on TV to the living Channel, sets it to mute and then puts on a CD.

I notice that most of the US networks have translucent logos and animated ones on the news.. Guess this stops burn in..

I would have thought the ads during the program would take care of the TV3 logo?

I've had a bit of image retention lately with the radar from GTA, but generally only notice when I start watching a football game, when the picture is mostly solid green.

JonnyCam: I would have thought the ads during the program would take care of the TV3 logo?

Its important to differentiate between IR which causes a bright after-image on dark backgrounds and IR that causes dark shadows on light/medium intensity backgrounds (known as MgO sputter).

The latter (which is what the OP has), takes considerably longer to build and to remove.

I suspected it was more than image retention. Its persistant dark pixels on light backgrounds not bright artefacts. MgO sputter?, hopefully it that and not irreversible phosphor aging (actual image burn).

It has reduced by running the scrolling bar overnight. I'll watch the news on zoom from now on and hopefully it will continue to fade.

Would still like to find an app to blur out the logo so I can watch without zoom.

I'm going to contact Panasonic and se what they have to say about normal viewing habits causing image burn. Like Jonnycam says, the ads and other content should have avoided this problem.

Regards Allen.

Image burn is generally what you would term a scar on the screen that is visible when the display is turned off.
Image retention (the type you have) can certainly be perpetual if you keep watching the same source that caused it, but I'm quite confident that you will see it diminish over time.

It don't know if this will help, but years ago on the green button it was reported that getting a sample and inverting it, then displaying the inverse aligned the same will speed recovery.
