Screen burn and other problems - LCDTv ??
Discussion
We have a Philips HDTV 32 inch model, not sure of exact model number. Its about 3 years old and recently I've noticed a rather perculiar display feature... the issue may have been triggered by using Mr Sheen to clean the screen - other half duly chastised.
Its as if the screen has a polorising filter that has been wash away in part which causes the sides of the screen to be darker on one side, lighter on the other as if a layer has been washed away. Further to this, if a screen graphic is left on for a long period - sky planner or say the Weakest link, it burns into this effected area and is visible for quite some time.
I've put some pictures below to try to show what I am on about. Any ideas or suggestions on fixing? I really dont want to replace the tv as it works really well other than this issue.
The picture works perfectly well in the side areas but at a different exposure

Mr Sheen is heavy on the silicone, and I doubt the screen has had anything removed bar some ingrained dirt.
Get a baby wipe or one of the dedicated spray or wetted tissues, and remove the crap Mr Sheen has left behind.
As for the image retention - get a VCR/DVD Rec with analog tuner, and choose that input, leaving the TV on with white noise for 10-15 mins.
After that, get a THX DVD (Star Wars) and use that to set the brightness and contrast to a lower correct level.
That should sort the retention issue, assuming you don't leave a picture paused for longer than 10 mins.
Normally LCD is less prone than Plasma to IR, but not totally impervious.

tried the screen wipes from work, no improvement or change. The screen burn only happens in the middle area of the screen inbetween the two outside wibblywobbly borders.
Will try the suggestion of the snow though, we have no analogue tv signal now so I'll just put it on that for a bit

Can see better now that I'm not on the iPhone, and I really don't know how that could've went like that other than possibly pressure on the LCD panel.
Not unless it's some sort of light bleed from the ambi-lights?
Final alternative, now that I think of it, possibly some Mr Sheen seeped round the back side of that filter panel?
If so, then it's still going to need to be taken apart to be removed.

A lot of screens use an anti-reflective coating that can conceivably be washed off with the "wrong" products but I'd be surprised if it caused these issues.
How bright do you run the screen? Most tend to be set quite bright from the factory, my 7 series panasonic plasma is toned down slightly and I can leave it on BBC news for 10 hours with no image retention issues.

Philips usually run very high contrast wich does nothing for the picture quality but in my opinion is a major contributor to this type of issue and deffinatly the image retention, ive lost count of the number of philips sets ive turned it down to get rid of image retention. The type of fault here is a delamination on the edges of the panel, when you see it in RL it looks like a fluid has creaped in between two layers of the screen, im pretty convinced its caused by the screen running too hot.
