Nice tear down! 

Just wondering for the scratch on the LCD... Is there any way to restore such a scratch on a display. I know that in some cases there is a plastic film you can peel off. If the scratch is on a the actual glass/polycarbon? Any paste of some kind someone can apply?

There was a big annoying scratch on an equipment screen. I was applying some petroleum jelly every couple of months. It was hiding the scratch almost completely. Couldn't find something for permanent use (actually no one could verify it wouldn't attack the type o plastic).

An interesting tear down, Mike, but can I offer a suggestion.

There's so much camera movement that it almost gives me vertigo - perhaps keeping the camera and board in a relatively fixed position with respect to each other and pointing out the various features with a pencil or screwdriver or the like would steady the image for those of us subject to sea sickness.

That brittle solder for sealing ICs might be something like Au80/Sn20 -- very high melting point of around 280C (and quite expensive too).

Good teardown and explanation, but otherwise I agree completely. The field of vision is moving too much for enjoyment.
