Thank you for the videos Chris. To address a couple of questions raised by others:
The blog page said video was pending and then downloaded in a new window in a new web version of DIv X - very cool and no problems except for a bit of a delay.
I needed to get in there in my DL2 and remove a hair and a couple of bad dirt spots and was inspired after watching the vid. Yes this model does have the same (nearly) fold down mechanism.
Not having a screen to change meant I had no dedicated tools. The swiss army knife toothpick and tweezers did the job.
The frame that holds the screen folded down but on the DL2 there is a gold rectangular u shaped spacer that sits on top of the screen and helps hold the frame under tension - very flimsy and slippery. Manageabe though and the whole assembly still works so i'm still looking for an excuse to upgrade to the K?D asap.
