That was weird! I was looking at this forum last night for the first time in months, and POP! The lamp finally blew after about 2 1/2 years and almost 11K hours. The stats are:
But I forgot that I had reset to factory during a firmware update with something like 2750 hours on the bulb, so it's more like 13,650 hours total. Not bad.
So it's probably best to keep your lamp on high bright and power-saving startup for longest life. Just saying.
Thank goodness for my backup lamp. I bought a Y66 a long time ago, and when I went to put it in I found it had a molded plastic handle that snapped off quite nicely with pliers. I see the original was a Y67 with a fold down wire handle. The new one works fine. Now I just have to get my lamp warranty to pay off with a new backup lamp.
Update: It appears that my bulb warranty and extended warranty are not worth the paper they're printed on. Repairtech is/was a scam and is kaput. I did just score a replacement backup new genuine Y67-LMP off ebay for $85.
