Default 8u screen for parts

anyone have an 8u which is broken?
I have a friend who accidently wet his screen while cleaning his radio. someone must be sitting on an 8U which is only good for parts.

He could dismantle the LCD and clean the contacts and contact strips with alcohol. (I'm assuming it's working, but the display is messed up)

Just a thought.

Default only half working

he says that only half the screen is viewable.
no display on the other half.
if he had to program a new plane in he wouldn't be able to do it.

Nod.. If he's technically proficient enough to replace the LCD, he should be able to take it apart and clean the contacts and contact strips. If half of the display is visible, the display driver is probably still OK. What I think happened is that gunk got between the pads on the PCB, LCD itself, and the strips that provide continuity. He may need to desolder a steel retainer to pry the glass. It's a chore, but no more difficult than replacing the module. A little denatured alcohol and an acid brush should make it good as new.

I'm not exactly sure what type of module it is, but usually LCD's are a sandwich of a PCB, glass, and silicon/conductive strips. I could have a look in my 8U later if need be.
