Opening Up an AP-470

[BigJilm]

Hello,

 

My one month old AP-470 has a single key that often pops slightly out of place when I play. I'm sure its a simple thing to fix on my own. But for the life of me I do not see any way to open it up to access the keyboard. The only obvious screws (at the top rear of the piano) open up to a chamber that is empty except for the speakers. And in any case, it is covered by a sheet of unremovable red felt). Does anyone have any idea how I can open this thing up and access the keyboard? There appear to be about 20 screws on the bottom of the main component, but the only way to get them off would be to turn the 100 pound piece upside down and I don't even see how once the screws are off (assuming this would even give me access to the keyboard) how I could flip it back right side up without potentially damaging all of the fragile electronics inside. 

 

Any ideas? Anyone done this before?

 

Thanks in Advance!
