I am not 100% on this but I think that this may be the result of some damage to your blue polarizer. Don't ask me what that is but I believe that it is a heat related issue. My old files show that I made some adjustments to the fans to move more air. The adjustments made the fans noisier but I'm still on my original bulb and I bought my Z2 during the first month of their release.
I am not sure if this is in the service menu or the factory menu but this is from my old notes. Please take care to write down your original settings.
There are 3 ways to change fans speed:
1. Setting 108 = 3, which is the high pressure mode designed for high altitude usage. Min and Max fan voltages are up a bit compared to normal. PJ gets slightly noisier.
2. Another way is to change individual fans values
110 through 117 - for full lamp mode, 120 through 127 for eco mode. just up the numbers 10% or so. (This is what I did)
3. Set 108 to 4, which means constant manual speed, then adjust 139 through to 142 from default 100. If you put it all to 145 with the old air filter you would probably get dust blobs. (I don't remember what this means)

You're talking about a few screws and "whamo" the top (silver) cover comes off. Then give it a little blow and that's all there is to it?
It is very easy but care should be taken. The worst part of the whole thing is getting your picture square with the screen when you put it back up. Rather than a can of air which may have oil or a liquid propellant in it I use these... http://www.staples.com/office/suppli...P1742:CL142034
