Just wanted to post an update that the bulb blew in our DLP set last Thursday. We bought it in November of 06 so we have had it approximately 485 days. The bulb is covered under the warranty but the repairman is taking his sweet time getting us a bulb so I ordered one myself as a backup and put it in tonight. It cost $150 with free 2 day shipping and 1 year warranty from www.dlplampxpress.com
so not a bad price really and it was super easy to replace.
When I replaced the bulb tonight I checked in the tv's menu and it had 5487 hours on the original bulb. So that equals out to about 11.3 hours a day every day since we bought it that it has been on. LOL we really need to turn that thing off once in a while.
