Emax

Alan-

The LCD must be soldered. I don't know if the system checks whether  
the LCD is displaying or not.

There are 2 kinds of LCD- EL (Electro Luminescent back light - which  
takes 110V AC), and LED backlight (+5v or +12v - not sure which).  
When I got mine, I got EL, but there are two rows of 8 (16 pin).  
There are contacts on the other end for the backlight as well. I got  
additional pins so I could put the old display back as necessary (for  
test purposes). The pins were only like $2.


You would not populate pins 15 and 16, and would connect those other  
two pins at the opposite end of the display for the Backlight....


However- that is assuming that you have an EL backlight. if you have  
LED backlight, the high voltage could immediately blow out the LED  
for the backlight, and could possible damage the main emax board.

You need to determine which kind of new display you have, then we can  
go from there.
