Hi, I've just bought a Philips 28PW6515 and I was pretty pleased with it after playing with the personal setting for a bit. However, after a while I started to notice somthing like digital noise occuring for one frame (at 50hz) whenever the screen jumps from very dark over most of the screen to bright white over a large portion of the screen. This error occurs on all input methods (SCART/RF etc) . The 'digital noise' is a random spread of dark rectangles, sometimes horizontally stretched sometimes almost square and they last for one frame, so they are very hard to see, until you've seen them once. (Then of course you see them all the time!) The TV needs to have been on for about 20 minutes I think, before the noise occurs. If you leave it on Standby, this counts as ON. I had an engineer come out who recorded this as an 'intermittent processing fault' and I had the TV replaced as it was very new. Got the new set back yesterday, plugged everything in and everything seemed fine for a while, but, annoyingly the same thing occurred again. This is really annoying. I'm wondering if anyone knows whether this is a known fault of the 28PW6515 and whether it is fixable, or whether I have been incredibly unlucky in getting two sets with exactly the same problem. I am wondering whether to send it back and get a model by a different manufacturer, something I'd rather not do, because I quite like the set. I am guessing this is some kind of digital processing fault by the looks of it.
