BE-300-How do I open it to remove the touch screen?

As I remember it has some plastic bulges that fit into some indentations. Some gentle prying toward the bottom should show you some success.

To get the things that hold it together apart you need to press in on one part and lift up on the other, but don't remember which.

If you don't get it email me and I will go dig my old one out of the junk box and see which is which.

It, by the way has a good screen/touchscreen I think, the light circuit got busted on it and I can't get parts.
