Thanks Dave and everyone else for your help and suggestions.
I think the £1,000 limit does apply Dave as this is a student insurance plan not a home contents policy, so there are certain restrictions such as a £1,000 or £1,500 limit per claim - None of which should effect me as I paid less than £1000 for the tv, I got an excellent Christmas deal for it from Tesco Direct!
Nevertheless, I am gutted to say the least about the tv, I hardly ever used the tv because I liked it so much and didn't want to wear out the neon strips inside or whatever they are, but what a waste that was now the screen is all cracked. Nevermind, hopefully the insurance company will give me enough to get another nice one. - I have noticed the prices in HD LCDs seems to be dropping vastly at the moment.
Thanks again to everyone who posted for your time and comments.
