Cleaning cobwebs from philips rear projection tv model 51PW9363/1
Hello: I have a Philips 51PW9363/17F rear projection tv that has accumulated cobwebs inside the screen. How do I take the tv apart to clean the cobwebs? And is there anything special that I clean the inside of the screen with once I get it apart?

I had the exact same problem and the fix is easy to do. Unplug the TV first of all and wheel it out so you can easily get to all of the rear screws.
Remove the screws from the ventilated back panel (the piece of wood with a bunch of holes in it surrounding the AV connection panel.
Remove the wood panel you just unscrewed.
Remove all screws from the upper plastic case on the back.
Remove the back plastic case carefully. This is a little tricky due to two metal pins that it hangs on. Lift it upwards and you should be able to free it from these pins
At this point you should be able to see the entire workings of the TV, and consequently the massive amount of dust that has accumulated.
Carefully take a vacuum and remove all the cobwebs, taking care not to bump the mirror or the lenses.
First, I used some compressed air to clean off the lenses and then used a clean microfiber towel to remove all the dust from the lenses, the mirror, and the screen on the inside. Make sure the part you are wiping the mirror and lenses off with is free from any dust or dirt or you will risk scratching them.
Reverse the dissasembly process to put the case back together.
I went through the convergance settings at this point and found that they were all out of calibration and as such recalibrated them. Use the mulitpoint calibration for best results.

I really would love to tell you that you can do this on your own, but I would really suggest taking it to a professional and having it fixed. If you don't know what you're doing you could just cause more damage.
