Hi Jokeyman, new user here. Tried sending you a private message but couldn't. I've seen from some posts that you've managed to fix some casios. I have an AP450 I'm trying to dismantle to get to the keys to fix some dropped keys and have hit a wall.. Was wondering if you could help out..?Â

I wish there some better pictures. I can only guess-that in addition to the top panel being removed, there might be hidden screws holding the side panels together. It would be unfortunate if-upon assembly, parts that hold this sliding panel in place in their grooved slots-were glued together. It is possible. I like to think-for the sake of Casio service techs who would need to obtain complete access to the mechanicals-and electronics-this would not happen, but being a service tech myself-I have seen instances of seemingly impossible assemblies-not designed for the poor tech who might have to repair something-like our newer cars! I'll do some more searching. Youtube might have someone who posted a disassembly for this Casio or something similar. I sometimes have found solutions to problems by looking for something else, odd maybe but there you are.

something else that just occurred to me. The portable Privias, specifically my 560 and 350-all use long screws buried under protective plastic panels for each one-that are responsible for holding the upper control panels in place. I could remove every visible screw around the perimeters of the bottom panel-sides, back front underneath-and the top panels will still not lift off at all. I don't know if this helps as I'm sure you would have noticed screws underneath if there are any. I've also had to use extra-length electricians screwdrivers to unscrew almost invisible screws holding some other keyboards together-especially those constructed with particle board which often use small L-shaped metal brackets. there may be screws inside the side panels of the AP that need to be removed to get the lid free. I've unfortunately had the experience specifically with 1-2 older Generalmusics and my Alesis Fusions where it is literally impossible to take the "dog-ear" end caps apart unless I completely disassembled the frame! Why I am a little nuts, and don't do this professionally anymore. But I digress. I, as a madman did it anyway. Look at this, not exactly like yours, but might be close. I don't see the routed-out slots on this one though.
