Grrrr. I just ordered a replacement lamp from Mitsubishi's parts web site and at the conclusion of the order process they displayed my complete credit card information on a non-secure web page.

yikes.

may i ask, what TV model you have and how long did the bulb last you?

It's a 21-month-old WD-73727. The original lamp has not gone out yet. I just ordered one so I would have it when the time came.
