Twice now I have had the IN72 freeze up on the "Setting up image" message, and as far as I can tell the only thing I can do at that point is to *UNPLUG* the power chord. Nothing on the remote (including power-toggle) does anything, and even hitting the power button on the pj does nothing. In both situations I had friends over for entertainment and didn't want to wait an hour to see if the problem would resolve itself by sleep timer kicking in - but I did wait about 10-15 minutes on the first incident.
On the first incident I had run past the 4000-hour mark (was actually at 4400+) and so the "Replace Lamp" message would come on at startup. I have a failed IN72 with a good bulb (1000 hours) and I've been meaning to swap out the bulbs, so I did that, cleaning the dust out of the pj in the process. I reset the lamp hours and used it a few times with no problems, but three days ago the freeze problem happened again. This time I didn't wait very long before unplugging (but waited about 15 minutes for it to cool down before starting it up again), and after that it worked fine. I've used it a few times since then with no problems.
I only ever feed HDMI video into it, so I've now disabled the component source that I had left enabled before. I've also changed all my sources to send 720p, just in hopes of minimizing the different input resolutions that it is trying to switch between. (I would make it 480p, but then my HTPC would be unusable, and I'm still a little confused by the whole 720x480-isn't-16:9 issue, but maybe I'll educate myself to get over that soon) No idea if any of that is likely to make any difference.
I'm running firmware version 2.8 (it lists "setup version" as 2.6). I don't have the proper cable to upgrade firmware to 3.0, but I would get it if I thought it would fix this problem. Correct me if I'm wrong, but I don't think the FW change from 2.8-3.0 is likely to do much for me...
I've been running it in "eco" power mode.
Any idea what would cause the IN72 to freeze in such an icky way? I hate to just unplug it from the wall (especially when it had the old bulb in it), and now if I'm having friends over I feel like I have to start the projector a half hour early just so I have time to fix the problem if it happens again.
Thanks in advance for any advice...
