Thank you both! I'll delve in ASAP. I'll let you know how it goes!

My PX-5s was dropped and now many of the upper keys do not 'pop' back up. Feels like the hammer action mechanism is broken on those keys. I'd like to open it up myself and attempt the repair but am not sure if the parts will be available if I need them. Anyone have experience with this, would I be wasting my time trying to repair it myself? Thanks for any advice!
