Emu XL-7 & MP-7 User's Group

Hello,

Umm.. my XL-7, god this sounds awful... was rained on through an open
window while turned on....

After finding it in this condition and giving it two days to dry out I
switch it on and every LED lights and the screen displays a series of
solid boxes across the top row and little else. That's all I can get
it to do as it never begins to boot. 

any ideas, or am I out of luck? 

thanks,

Mattb
