I have had a quote to get it fixed for £50. Given that it is an 8
year old set, and that I can get an equivilent new set for around
£150, do you think it would be worth getting it fixed?

If the fixed tv lasts more than 2 or 3 years I guess it would be worth
it to stay with the current set. On the other hand, if the fixed set
breaks in a year or so, I would be better off getting a new set now.
Any thoughts?

Dave.
