I've got an Advent 32" LCD Tv that i've had for about 18 months now and about the last 4 months its not been quite right. I turn it on in the morning or when it hasn't been on for ages and it works fine for about 10 minutes until the colour on the picture goes funny. It's hard to explain but it looks like a sort of multi coloured barcode burning across the screen and it gets very jerky indeed. This lasts for about 20 minutes and then its absolutely fine again. It is starting to get pretty annoying, especially if i want to watch something as soon as i get home from somewhere. What can i do about this? Should i just push it over one day and claim accidental damage on the insurance?
