In retrospect, the smell might have been coming from my son's movie choice of "Dylan Dog". As suspected, it would seem to have been a little gas coming from the bulb, which within a reasonable amount of time went away...though the movie still stunk up the place.
So the bullet points from my experience would be...
1) Take some pics of the bulb in the housing including the tab placement.
2) Expect resistance when pulling the housing out and putting it back in.
3) Make sure to wear the plastic gloves provided by Pureland Supply
4) Be careful when lifting the original bulb out of the lamp housing, keeping the spring/screw in place.
5) To reapply the hardware clips and screws that hold the lamp in place against the front of the housing, you'll need a screw driver with a magnetic end. The screw on the inside of the housing is recessed in the corner of the housing and too hard to get to with one's fingers (this took sometime-I felt like I was playing the game "operation").
6) I had a tough time reattaching the clip (at the end of the electrical wire) to the bulb prong on the base of the bulb. The prong is bent towards the bulb and leaves little space to use my fat fingers to reattach the clip to the prong. PPL with slender fingers may not have this issue.
7) Again, use your picture taken before you've started the replacement process to check the placement of the tabs to ensure the same position after reinserting the internal bulb housing into the external housing.
I printed off a copy of both BigmounthinDC's pics and Mortisemaker's pictures and instructions (huge help) to refer to when making the change out. I can honestly say, I may not have been able to do this project without their pictures and help....thanks guys!!
Let me know if anyone has any questions? I'd feel much more prepared and confident making another change out down the road. The cost diffence between the bulb only and the housing the bulb is huge....I am more likely to keep my planar for a longer period of time, now that I have an cheap option to replace the bulb vs weighting the cost of investing $550 (shipping and tax) into a used projector vs using the cash towards a new one.
