Does anyone know the electronics inside these things?  I have a powerbraille 
80 that has several dots stickig up all the time.  I know it's not any kind 
of dirty or miss-alinement.  The staying up dots work up and down by 
pressing just as easily as the ones that are supposed to be up.  I suspect a 
failing electronic component somewhere in there.  Sure would like to not 
have to pay the $800 that fs wants to mess it up worse.
