Ok we know burn-in isnt as big a deal as in the past with Plasmas.

 

However I'm just curious as to if anyone here tried to get one replaced under warranty and what was their experience like with the retailer.

 

Please also mention the retailer in your experience. CHeers!

doubt any manafacturer would accept burn-in as part of their warranty - it's not an equipmet fault of theirs, and I'd say they have some warnings in the manual.

I woudn't worry, I play a heap of games on my plasma, and I see after images (like the HUD in GTA) but only on solid colour backgrounds, adn it's not burn-in, just the after image effect.

The retailer woul defer to the manafacturer in the case of burn in I would think.

Considering manuals for older Plasma TV's warn of the issue and how to avoid it you probably aren't going to get far. If I wanted to complain it would be with CNN, it's their logo that's burnt into my TV!

Screen burn is pretty much a non issue for any Plasma's newer than ~3 years.

Yeah doubt you would have a leg to stand on.
There's probably a bit in the manual about it to cover the manufacturer.
After that it's your responsibility to look out for it.

As above, it would be your problem. In saying that, some manufacturers will for a fee, help to remove it for you.
Having worked for a big box retailer, for 5+ years, we never sent away any TV's for screen burn. We just never accepted it from the very few customers who asked us to. Also, any of the demo TV's that got screen burn due to dvd menus being left up, instead of video loops, we managed to remove 99% of the burnt image instore.

Frankly - I don't like your chances of getting a store to take a burnt in plasma back...
Some will happily send it back to the importer, but with the proviso, that if it's not a warranty, you'll have to pay for the repair.
Sometimes, we just need to put our hands up, be honest, and say 'Oooops, I stuffed up... help?'.

Thanks guys.

 

I only asked because about 1 month ago, there was display model at Noel Lemming that had burn-in which we noticed while the sales rep was telling us that burn-in was a thing of the past.

 

Needless to say he was quite taken back when we pointed it out to him and he immediately jumped on the phone with Panasonic.Laughing

I dare say that that tv had been left on a static image for a long, long time.

I have 2 Panasonic plasmas - one for gaming (ex htpc use - 5yrs old) and one for the main tv(18months old). No issues here.

Sounds like one of the NL sales people - I cant say that I have found that their sales people seem to be very clued up on TV when I have wandered into their stores - HN and JB HiFi seem to be pretty good though - Their staff do seem to 'specialise' a bit more.

Anyway - Plasmas will get some 'image retention' (I think they like to call it that now) if you leave something on the screen for a while (A very long time) - Sometimes you can even see it after you have turned the tv off - but you have to look pretty hard (with the right room lighting to see it). I have also found that it seems to disappear pretty quickly with normal use - So I would say you would have to work pretty hard to actually damage the panel permanently ie a static display for a few days/weeks may do it.

Also - some people swear by running breakin images - basically a repeating slideshow of coloured screens that will 'break-in' a panel. General opinion seems to say this isnt necessary - but it could well help if you have somehow managed to get a major case of image retention.

This site has a tool that may help:

Even image retension doesn't discribe what the reality is with the modern display.

Plasmas, or the cells themselves can hold onto the charge that makes them glow and/or lose the ability to glow as strong as surrounding cells.

These days though the lesser or greater issue is from aging effects. It is lesser because display lifespans are longer, however greater because they have initially higher luma(higher lumens, brightness levels). Because the luma decays in a log type curve known as a half life where the rated hours is where the display luma is half that of new, the initial levels or first few hundred hours use is where you can decay sections or pixels at a greater life span aging. Thus the outright luma can be less with those areas.
Thats why you may see after images at extremes, light on dark etc

It is worth noting that LCD designs can have after images aswell, due to decay of the LCD pixels acting as light filters. These fade with age along with the backlights which also fade with age. LCD panels with individual backlights could fade at different rates, where as side ilumination would be more generalised. But the filtering effects would be the same.

Washing away after images can be done, effectively you are just aging the display so the differences are just less, the age discrenpency is still the same unless you can run a negative image of the image that did the damage for the same inverse time period.
