Sanyo Z-4, what happens when bulb dies?

I'm coming up on the stated 2,000 hour bulb life.

Will the machine give me a warning?
Will it shut down or will it continue to run until the bulb burns out.
Could the bulb explode?

Do I just change the bulb at 2,000 hours or wait until something happens????

Even at $350 per bulb I think the projector was the best way to go.
cheapest way to get a 120" picture...



Re: Sanyo Z-4, what happens when bulb dies?

I have a Z2, which has a "Lamp Replace" light below "Warning" &
"Power." The Lamp Replace light came at approximately 3,000 hours (I
suspect EXACTLY at 3,000 hours). I tend to ASSume plenty of safety
factor built into specs, so I continued to push it for a while; however
I did read somewhere that the bulbs can potentially burst, so I finally
replaced the bulb at around 3200 hours. (Interestingly the Z2 gives no
lamp life spec, but I don't think the projector "knows" when the bulb
is ready to blow, and that the light was simply set to go off at 3000

The replacement was easy, but I was surprised the new bulb didn't
increase my brightness as much as I had heard (some sources say the
bulb's brightness reduces 50% over its life.) What's worse is that I
now had a dreaded "dust blob" and some color irregularities. The left
edge of my screen tends to be a bit reddish, and the right side, a bit
yellow-greenish. Needless to say, I am a bit disappointed. I was
careful during my bulb replacement, following instructions to the
letter and cautious not to introduce dust into the projectors

I love my projector, and hope this isn't typical of bulb replacements.
I would love to hear other experiences; but the next time my light
comes on, I will really be thinking hard about putting that $350 toward
a new projector.
