Hi, Recently purchased a Philips 28PW9509 widescreen tv which looked like i was happy with until the first time i viewed it at night. I was viewing the tv in an unlit room & noticed that all dark scenes & unlit dark scenes on screen appeared to be awash with a greenish luminence of various degrees depending on how dark the object on screen was. It was very annoying as it washed out any detail with this greenish colour. I then noticed that even with a blank black screen the greenish effect was very evident. I tried every combination of setting on the tv to remedy this problem. I have noticed it at daytime on light shadowed areas,but my eye is trained to it now. I got an engineer to view the tv ( through the day ) & he said it was fine. "It was not fine", anyway, i got it replaced for another new Philips but this one has the same problem but not to the same degree as the first. This replacement is alot better but would like to get to the bottom of the problem with this greenish luminence over the screen as it appears to be above the level of the images on screen. Any views on this issue from an engineer who has come across this problem & a possible adjustment to the tv in the service menu would be much appreciated.
