I had a couple dust specs in between the digitizer and the screen, and I peeled off the top bezel. All was fine, except that I was not peeling of the touchscreen, but instead splitting it in half. **The digitizer module is actually much thicker than the usual, e.g. compared PDAs and tablet PCs**

The digitizer looks like a resistive digitizer, and it has a thin sheet of metal frame just below the front bezel. On the top side of the reader there are 4 connections from this frame to the lower half of the digitizer, and it looks like these are thermally fused. So, when you pry it off, it peels the connections permanently. I tried shorting the layers using some aluminum foil, but it did not work. Finally, I tried the drastic measure, the Indium-gallium eutectic which is a wettable, liquid metal. Even that did not work. (Plus it is pretty hard to clean, so no recommendation there)

Anyways, I spoke to Sony, and ordered a replacement digitizer together with LEDs. It costs $69 FYI.

Looking at the digitizer, I do not think it is easy to split the LEDs and the digitizer. When I will replace it, I can post some photos if anybody wants me to.

PS: PRS 700 cannot be operated without the touchscreen, and as an engineer, I'd say that is not good a design. It should costs practically nothing to put a simple D-pad, but it gives redundancy in case of a touch screen failure.
Well....I don't know about that. What about devices such as the iPod Touch and iPhone? They're touchscreen devices with no way to navigate if the touchscreen goes kaput.
