One will work pretty well but you have to keep adjusting the contrast. Eventually the whole screen turns white.

Another goes from very dim to white screen about 30 seconds after startup is complete.

The last one displays colored lines all over the screen (odd for a greyscale display?) that change color when adjusting conrast. The rest of the screen is black.

Seems to be the story of my life regarding 1xx PB's - I swear I've had soo many dead ones.
