Does rear-projection TV have shorter lifetime than CRT?




I'm asking this after hearing that the rear-projectionTV has short life.
Does rear-projection TV have shorter lifetime than CRT?
What are the general lifetime for both of them?

Its not really a sensible question in that CRT tubes life usually govern the life of a tv set at I believe somewhere between 30,000 to 60,000 hours, which is many years normal use. It would not normally be economic to replace a tube unless it is a warranty job.

Rear projection tv's I understand use replacable projectors which I have read should last 10,000 to 20,000 hours. They are expensive to replace though. You should remember that this type of TV is probably aimed at a proffessional market with nearly continuose use envisaged, so the need to be repairable is quite important.

Please feel free to correct me though if you know better?
