The good stuff starts a few pages in I did a "summary post" of what I read but haven't had a chance to try it out.http://www.avsforum.com/avs-vb/showthread.php?t=1223098
I cleaned mine again last night.
I have 1879 hours on the lamp.
I used a very hot wet Microfibre cloth and then a Lens cloth (for cleaning glasses). Didn't feel like using chemicals.
The Lamp was clean and nothing came off on the cloth. The prism looked clean, however when I wiped it, it left black carbon on the cloth.
I did it a second time and it left a little less. Third time nothing.
I dryed with the Lens cloth and re-assembled.
I don't have testing equipment, however I would say it was 10% brighter (a Guess). What I really noticed however was the colour. It was more vibrant, which gave the picture more detail.
I had noticed my colour was slowly going off (I use the S&M disc), I just thought it was the age of the lamp. Cleaning it put the colours right back to where it should ( I used the disc).
The stuff that came off the prism was like a carbon. I thing it acted like the Prism was wearing sunglasses. Dims the light and screws with the colour.
I have decided to do this once a month. Well worth it.
It is also really easy. 5 minute job.
I have some photo's of the inside and the crap on the cloth. I will post in the next few days.
I must say it is a squeeze getting your hand in the enclosure. Use small hands.
