Blurry/Hazy picture on Philips Tv

Question

Hi - 2 and a half years ago i bought a Philips 36pw8719 crt from currys. Over the last number of weeks the picture has become blurry/hazy and it seems to be getting worse. Its not that noticeable when there are closeups but any scenes at a distance are not good. Any text that appears on screen is awful though. I have phoned Currys and they have told me that because it is over the year long guarantee period there is not much they can do(typical really). I have seen somewhere else about a G1 intermmitent short problem(no idea what this means). I paid approx £900 for the set in the UK here. Any ideas?
