Here is a useful link on replacing the PB 180 screen. This is one of the easiest PB surgeries, so take heart. The trickiest part is getting the thin ribbon connector to let go of the ribbon, and getting the ribbon properly latched in the new screen. Take a few minutes to figure out how the latch on the connector works. When you figure out what to slide and in what direction, the connector is easy to use.

Good luck.
