Eliminating LCD Clouding - Recommendations?

[JJ]

So recently I noticed on my LCD what apparently is referred to as clouding or backlight bleeding - on the left corners, top and bottom, the shade of black is noticeably lighter than the rest of the screen. Is there any way to counter this effect?

Some on AVS forum recommend gentle wiping of the screen with the soft lens cloth, some say leave the TV on and let it warm-up and it will fade away. I have already informed Philips and they are sending a technician to my house on Tuesday.

But I wanted to see if anyone else has had problems of this kind and has dealt with them.

It isn't entirely distracting - but once you notice it you always notice it. Having that ol' Ambilight feature on helps distract from it, but that's just skirting the issue.

Thanks in advance.
