That's a heck of a job to be taking on yourself! Seems a fairly new tv, isn't it under warranty? How long have you had it? It should be reasonably expected to last for longer than a few years.
Have you posted your question on any consumer help forums such as www.moneysavingexpert.com? They're fairly clued up on consumer rights and will be able to advise.
http://forums.moneysavingexpert.com/forumdisplay.html?f=173 is the forum you want. You'll have to register and start new thread (blue button left hand side of screen towards the top)
Failing that I'd get the professionals in!
