Just the one, there was one screw and 2 clips holding the pcb in but the tricky part was bending the leads connecting the lcd screen to it. There is no ribbon cable.
I teased it open a little bit at a time and propped it open with anything suitable to take a break, eventually got it open enough to work on.I wouldn't do this more than once as the solder joints could eventually break.
The toothpick points to the empty smd pads for the CC led.
