Inspecting LCDs and Polarisers

This is where I made one of my big mistakes. Unscrewing the tiny LCD Panels here will very likely put them out of alignment. They have to sit *exactly* where they are.
The other mistake I made was thinking I could clean the Polariser - The polarising layer is so delicate that I ended up just making it worse.
Remove the 4 Screws - 1x7mm Machine Thread
The second pic (Blue Arrow) is one I haven't touched yet. It shows where the Polariser has been scratched all the way up. This is either due to heat, or dust from the fans running up the polariser and damaging it on its way past.
The third pic (Red Arrow) I tried to clean with a cotton bud - Note the tiny scratch marks. It didn't have any effect on the pre-existing scratch marks.
