Yes. The Z1 popped last week after 280hrs. I had a little bit of warning before it happened. The pj went really quite dimm. The unit is only 3 months old too. I posted it for warranty today. Hopefully there'll be a quick turn around of 2-3 weeks. Anyone else had this problem? How likely is is it that it will be free repair bunder the warranty? Any ideas how i could argue this. Is it the bulb thats faulty, or the units thermal management? New bulb or new unit? Any advice would be appreciated. I'll keep you updated. David.
