Hi, I bought a Philips 32PW6518/05 unit about 3 months ago. Everything had been fine on it until the last few days. I have noticed a wavy interference pattern. I shall try to describe it: The lines are vertical and run from the top to the bottom of the picture. They appear as regularly spaced regions of brighter and darker versions of the picture (i.e. no loss of picture information such as shapes in picture, but rather varying levels of brightness). The effect is most pronounced on the left hand side of the screen and decreases in severity towards the middle of the picture. The effect is limited to approximately the left third of the screen. The effect is present irrespective of the source (Cable, AV, SCART). The effect scales with the varying zoom modes (i.e. is independent of the mode selected) It is not affected by the sound mode (same effect for mono as stereo etc). I set up a different TV set in the same area to see if there was some sort of odd interference, but could not observe the same problem. Has anyone else experienced this or have any suggestions as to what it might be? (Note: The Philips website vaguely suggests switching off for 20 mins and repeating up to 5 times, presumably to degauss.) Thanks in advance, Conor.
