i got my Osram from one of the websites a couple of pages back. it was not pricey and fingers crossed im happy with it.
As for cleaning the prism- its easy and it definitely helped a bit on my pj 4000 hours in. Not mind blowing but there was a difference. All you do is remove the bulb. If you look straight into the pj where the bulb was you can see the prism in the back. Cant miss it really its not small and its the only glass in there once the bulb is out.
I used a qtip covered in lint free cloth to wipe it down as it is a pretty tight fit in there for my hands.
Well, I didn't see your question until now. I haven't been reading this thread much, for different types of reasons.
But, regarding the question about a Osram bulb being dim for 5 minutes, no that would not be normal. But as for why it did that, the most obvious I guess would simply be something was a little off about the bulb, or there wasn't a good connection somewhere. Especially if it wasn't a slow change and happen all of a sudden.
If its still working good then most likely its OK. I'm having better luck with the Philips I got, than any I tried from the company JVC uses. Yes, the "other" companies besides Osram & Philips that are making bulbs that people can buy from, are a hit and miss regarding quality. Mostly a miss when it comes to front projectors. When I say other, I do mean copy types of no names. Also, other than Oscram & Philips most manufacturers of bulbs that build for companies, don't sell the bare bulb's.
Any of those links I gave only use Osram or Philips, far as I'm aware of for this bulb. Honestly I don't know why anyone would buy a JVC brand lamp for this projector, with the Osram replacement so easy to get and much cheaper. Philips is a little more tricky to get in the USA for some reason. I mean its easy to change just the bulb and I already know it works better, and that's my opinion of course.
