Yeah, I'm on my second bulb for my Z2, I think the first one lasted around 10yrs, lol. Recently I upgraded my DirecTV DVR and HD receivers and now the Z2 won't handshake anything over 480 with the new HD Mini. Luckily I was able to adjust my Denon to upconvert to 720 but I don't think the picture is as good as when it was coming from my old Direct HD box.
