Hi
Thanks for the info i did have a problem with my old poly with he 
battery and that is now fixed but my other one has nothing on the 
display but i can hear a very faint power hum when i switch it on.. 
just the sound of the power going through the circuits.
I have pressed the keys and nothing happens :(
Maybe this poly with no display is gonna be difficult to fix?
