Question about Panasonic PT-AE700U In Stock Multimedia Projector
I see dust inside the lens of the projector. This seems to cause a blueish tinge on the hole screen which is more concentrated in some areas. This is inside the lens so not cleanable other than taking the lens assembly apart - is that even possible? Is this problem reparable?

Obviously this is not the first lamp you have replaced in you projector. These are great projectors however, the LCD panels expire quite quickly. You will find that the spots are related to the LCD panels needing to be replaced. This is not an inexpensive maintainence solution as the panels cost about $1500 each.

Most likely, if it is a thermal problem, your main cooling fan has quit or is stopping after a short period. The problem is, I've seen several of these do this, and in every case, it is not the fan that has failed, but the Controller Board. And that is a very expensive part.

my dear friend, it appears that you must have opened the 3 lcd screws that are not supposed to be touched, if so then just forget reassembling the same as the convergence would be lost & cannot be manually done
another thing are the polarisers.if excessive dust had accumulated & if you used wrong technique in cleaning then the coating would have come off & you have lost everything , just change the entire lcd block.this costs a bomb.beter to buy a new projector

Firstly, try the focus function on the lens...
If spots are still present, then there is either:
a) foreign particles inside the lens
b) the LCD panel/s (guessing it's LCD, as you did not specify) have dead pixels
c) the colour filters are damaged
