Query: lamp problems

I have been through 2 of these sets in 6 months.. the "lamp" keeps burning out. The entire unit was replaced by the retailer the first time (it lasted 3 months) The second unit has just went out(it lasted 3 months). How may times during The life of this tv will i have to have the repairman replace the lamp?? Thankfully i bought a extended service plan If you buy this tv make sure you do the same..
