I have the instructions needed to replace the qualia.
I can scan and email them to you, if you wish.
Its very easy to replace the lamp, even if the projector remains hung on the ceiling.
I replaced the lamp in my projector, very recently.
You need two philips screwdrivers.
One comes with the new lamp/projector. This is the short one - no more than 1.5" in length from the tip to the end of the handle.. You might not be able to buy something this small.. If you need to borrow mine, let me know.. but I need it back.
You will also need a long screw driver - with a 9" philips stem (the metal rod has to be 9" long - typical philips screwdriver, but long).
Send me a PM with your email and I can scan and send you the instructions..
