EDIT! I turned the projector back on after discovering the 2nd anomaly, the one that makes the image unwatchable and indeed, as I'd hoped, that didn't reoccur. Hmm. It's not the first time that I've had a weird thing happen with this Epson 8700ub that was "cured" by a restart.
Hmm. I'm wondering if there are some things I can do in terms of maintenance, some things that will/might improve the image and prevent or delay deterioration/damage. Obviously, an important one is to clean the filter (which I just did for the first time last week). But I wonder if there's something else. Replacing the lamp (when the time comes) with a reliable lamp could be critical (read the below!). I have seen post(s) declaring that a faulty lamp has melted, fouling the projector.

I have changed my mind. If I were to go back a few weeks, with the experience I have now, I'd hope to just bite the bullet and buy a bulb off of Epson!
The movie I watched to test the $22 from Electrified was 2.40.1, so it didn't reveal the entire screen. When I turned on my HDTV image source this weekend (the obligatory British Open golf tournament), I discovered that there was a band at the very top of the screen that was darker than the rest, very noticeably. I'm color blind (partially) so I'm not sure, but I think that band, which covers the top ~6% of the screen area) is pinkish in tone. It doesn't make the image unwatchable, however, and I had the projector on about 18 hours over the weekend. I figure that it's not the bulb doing this, but something that's amiss in the projector besides the bulb. But here's the thing: I think it could be because of the bulb, it might be running too hot. Or, possibly something happened when I replaced the old bulb, something that pushed something out of alignment. What it is and what caused it are unkown to me.
This morning I turn on the PJ because I want to make sure that dark horizontal bar is still there at the top before I remove all the cables and put in the old bulb and retest (I expected that to have no effect and that the bar would still be there). Instead I do see the bar but I also see that the top ~20% of the image is cut off entirely, shows as white with that darkened bar on top still there. Now the image truly is unwatchable! I tried a different source, same thing.
Where I go from here I don't know. I have to figure the PJ may be history. Maybe I can have it repaired economically, maybe there's something I can do to repair it. I turned it off, haven't turned it on again ... maybe at least the 2nd condition will disappear, however naturally I'm not optimistic.
I have to wonder if this series of events aren't caused by this new bulb running too hot. Can anyone speak to that? Is there any way to determine if it is running too hot?
I didn't notice the fan being on more than usual but I watch my stuff with sound blocking earbuds in, so I might not notice. But I think I would have noticed the fan running a lot more somehow anyway.
The now persistent (i.e. first) non show-stopping anomaly:
