Cheers Chris. The dismantling was fun... and scary at the same time!

but got there in the end. Pleased with the end result!
Although I read the warnings, one of the screws from the back slid down and is now lost!! I can see it but there's not quite enough room for me to grab it even with tweasers!!
Luckily the 2 torx screws which held it down didnt disapeer. Any tips on getting this screw out or just leave it?
Im sure Im not the first to have this happen and prob not the last
Cheers
