Is my screen broken

Hello,

I'm fairly certain the screen is broken on my Cool-er but I'm trying to be sure. My cool-er did one of its (extremely annoying) firmware crashes and as I was busy I did not fix it for a month when it first crashed the screen was blank, however since I've fixed the firmware (and incidentally changed to the pocketbook firmware, which seems to work fine apart from the screen ) the bottom quarter of the screen is frozen on a jumbled miniaturized images.

This image shows what the screen looks like, is this an unsolvable problem. I;ve opened up the cool-er and the screen looks physically fine.
page turns are also fine.

That is a broken screen. It is the glass substrate that cracks.

Too bad! The screen is definitely broken. If you want to restore your Cool-er, you can use a Kindle 2 as a donor. Its screen is of the same model and it can be taken out easily.
Disassembling of both readers should not be a problem for a careful person, too.

The glass substrate is broken. The plastic eInk layer on top is still whole, which is why you can't see the break, but the curved line of the non-working area is a classic broken glass line.

It's a physical problem. Getting the screen replaced will probably cost more than a replacement ebook reader. Also, the screens are very fragile when on their own. Replacing a broken screen is a lot trickier than one might expect, even if you can get the part.
