Could someone tell me exactly what kind of cleaner and cloth was used? I'd rather not use something inappropriate and ruin a bulb (or something more expensive / delicate inside the projector). Where's a good place to pick up cleaner / cloth? (I'm assuming I don't have the right materials at home.)
I just swapped out a bulb for the first time on my RS10 and wouldn't have thought to actually clean the bulb or the pane. I did clean the filter (also for the first time) as recommended in the owners manual.
The bulb I swapped in does have some hours on it (a bit over 300), so I'd like to pull it out and clean it and see if that makes a difference. Also, if I understand the earlier postings in this thread, some are also cleaning the pane inside the projector that the bulb snugs up against (I just opened up the projector to swap the bulb and saw the pane for the first time).
I bought the projector used last year (including two used bulbs) from a guy local to the area. The bulb in the projector had a bit over 700 hours on it (if I remember correct). This morning, when swapping the bulb, it was at almost 2000 hours (1993, to be exact). It had dimmed considerably, but was still watchable in our bat cave. This second bulb (300+ hours) I just put in is not a whole lot brighter, but then I normally keep lens aperture at either 1 or 2, Cinema 2 setting, and normal bulb brightness (IOW, I don't usually blast out a lot of lumens), so it's fine for hopefully another 1000+ hours (I'd love to get 2000 on this bulb, too).
I also just bought a brand new replacement bulb, which will get put in when needed. It will be interesting to see the effect on brightness (and general color calibration) of a new bulb, for the first time.
One problem I've noticed in the last couple of months is a vertical "purple band" about 2 inches wide on the left side of my screen (96" inch wide screen, 110" diagonal). It didn't go away with the bulb swap, so if it's still present after a cleaning, I'll have the original owner over for a look (and I might have him over anyway for some color tweaking). Otherwise I'm worried that something bad has happened to the light panel inside the projector.
