Following on from another thread, has anyone any advice about this annoying issue.

I am a news addict and this addiction has now bitten me in the backside. I tend to mainly watch Sky News and both the Sky logo and the tick-a-tape that is permanently on the screen now have a ghost image. :mad:

Help.

Regards
John
 
Lower the contrast and find a white screen image to leave on for a couple of nights to help remove the burn.
 
Sorry to hear that John.

You could try the following:

Remove the arial cable from the TV and leave constantly on for 3 days (day and night) with the snowy/fuzzy screen on.

This apparently should at least reduce the burn in.

This advice was given to me to rectify a burn-in issue on a new plasma. It might not be so effective on an older plasma as the screen has already worn in.

Just something to try if your desperate.
 
Plasma technology is sensitive to burn-in. Manufacturers are keen to downplay this issue, but it is significant and as yet not totally resolved.

LCD screens have almost no burn-in issue. Plasma's use phosphor screen technology similar to CRTs, which is why they are sensitive to burn-in.

Plasma screen burn-ins can sometimes be "washed" out by displaying a series of gray or full colour moving images in the affected area for several hours. It's worth getting advice from the manufacturer on this.

For new plasma screens, the phosphor coating can be primed in the first months of usage, which should reduce (although not fully eliminate) the issue.

Even better would be for broadcasters to stop putting these static logos on their screens, bloody annoying in my opinion.

Clicking here leads to some more info on the issue.
 
Glad I choose LCD...............:D

But to offer a little practical help maybe..........
If you have a screen-in-screen facility, why not plonk another channel in the spot where the logo appears for a few days every now and then? Or is that not possible?

Which make is your screen?

I have a panasonic plasma and I have watched 24 hour news channels for hours on end for the last 2 years and absolutely no sign of burn in whatsoever. I'm quite suprised you have it.

It could just be image retention which is the early stages of burn in. I believe this can go away after a while. I have a 'screen saver' function on my screen which plays a white band back and forth across the screen. maybe if you have this feature you can give it a go for a while to see what happens. or give it the white noise treatment.

I'm envious of you owning a 50" LCD that can offer a comparable quality of picture to the plasma TV . ;)

Pioneer 507XD, which received rave reviews and has a very good

In fairness to my TV I never noticed this ghosting, it was my critical son that picked it up, and unless the screen is perfectly white there is no way I can see it.

To check your TV, it would need a white-ish screen and a very critical eye. I recommend my annoying son :devil: If you have ghosting then he will find it.

Don't worry, I'm very critical!

I also have an 'orbital wobbler' feature which I have enabled which shifts the picture in an orbital motion every 30 seconds or so by one pixel to reduce burn.

It doesnt help you much, but I think Panasonic panels are by far the best when it comes to screen burn, the newer panels pretty immune to it (as good as a CRT).
 
have you set the screen to allow for light burning(not sure howto set it got it on my plasma)probably not the correct term for it but does work to a degree as when i play the ps3 for too long it stays on very lightly and disappears after a while of watching any tv program regards jon

Without being too contentious - walk into a Costco where the TV's are displayed in high light levels and try and pick out the plasma's - not so easy now as it used to be.

I would assume every 50" would be plasma? :)

John
 
There are not loads of 50" LCD out there, but there are plenty of 49½" :)

The thing that still bugs me with LCD is the poor picture on moving shots.
 
I think refresh times on LCD's have now fallen to below visually perceptable levels. When I bought my LCD a couple of years ago, refresh time was about 20-25ms. This has fallen to around 10ms for most good brands and is below the 12-15ms refresh time which is reckoned to be the point at which it becomes undetectable to the human eye.
More important for gaming than general TV viewing.
Perhaps surprisingly, the best test for this effect is to view a game of snooker. Blurred balls - if you will pardon the expression - will show up this inherent fault the best.

This was the awful thing with 100hz scanning on CRT sets blurred balls, my trouble is that I am too fussy and I sit there waiting for it to blur, rather that watch the picture content. :mad::mad: the same with sound, when I know that a french horn is distorted, I just sit there thinking and waiting for it
