Marielmiami,
I'm sorry to hear that you're having trouble.
The lamps are a replacement part, so changing out lamps is not really a service issue, but more of the television's normal maintenance.
As for the color wheel, it spins rapidly, so it may require service after a period of time.

I bought an HL-P4663W TV on 5/10/05 and paid $2,403. In February 2006 it needed to have the lamp replaced. In April 2008 it needed to have the lamp replaced again. And now it has a very loud buzzing sound and it needs a new color wheel.
Is this normal for this TV or do I have a lemon?
