Why go to the dealer? I've gone directly to JVC the two times I've had the bulb replaced, with no issues. They fought me a bit the 1st time, but when I called last time, it sounded pretty routine(which is sad). Both times they called it a "one time accomodation".
So whats the highest hours anyone has on an 03 bulb? Mine is up to 380 or so, it would be close to 1,000 if not for my back up projector. So I can't believe there isn't someone out there with like 700+ hours yet. The tech didn't advise me to do so, but since the most recent bulb I've been running in high altitude mode. It adds a little extra noise, but as soon as a movie starts it's out of mind. I wish there were a report of an 003 bulb failing so I could pre emtively contact JVC for a replacement and avoid the innevitable 1-2 month back order.
