One of the white keys on my keyboard has broken. The unit was shoved into a van and it must have been in the wrong position for the entire duration of the trip. To explain further, the carrying case is too big for the unit and there was no padding inside the case whatsoever. The keyboard is a gift and I did not look inside before taking it home. Henceforth, the screw-up. I opened her up to take a look inside, just a peek, and four items fell out: 1) a small white piece of curved plastic (looks intact), 2) a small spring, and 3) two (possibly three) little washers (the 3rd was on the floor and I don't know if it belongs to the unit but it looks like the same color even if it is a bit larger and a layer of paint worn off). any advice would be appreciated. If someone can provide a link that leads to a webpage that is a tutorial on opening up the unit even more and replacing the parts that fell out (if these parts belong to the key that is), or a recommendation to a repair place (person) within the New York City (preferably Manhattan) area that is low cost. Thanks.

Try local Yamaha dealer. They may not make house calls, few people these days do.
What you might try if you are up to the challenge is flip the keyboard over- unplug it. remove the screws that hold the top and bottom shells together- do not let weight of unit rest on keys, especially when opening it up.
Look for physical damage to the keyboard action in the vicinity of the nonfunctional section. Check for broken printed circuit board. If you see any cracks, see where it ends and drill a small hole at the end of the crack to halt propagation. clean the varnish off the circuit tracks and tin the broken tracks first on either side of the break then bridge them with solder. Use a modest sized soldering iron and small diameter (rosin core only) solder. If there are any broken wire connections, resolder them. This may require part of the action to be removed from case- take pictures first before proceeding- make sure they show exactly where the connectors are and what wires are present. etc. You want to be able to refer to the pictures in the event you forget details of disassembly.
If nothing looks out of place, look for solder joints that do not appear to have flown out nicely- reflow them adding a little solder.
Verify the sound in headphones directly from the unit. The cymbal MAY be panned to one side or the other and will require higher frequency response than some of the piano notes.
Probably a cable has come loose inside the unit. The keys are scanned by the internal processor as a matrix of two contacts per key. Often the keyboard is divided into two sections.
You will need to have it repaired or if you are electronically adept, open the case and look for obvious problem.
It is NOT likely the keyboard is "killing the speakers"... OR the headphones for that matter.
I suspect the problem is bad switch contacts in the headphone jack that cut off the speaker line outputs when headphones are plugged into the pro keys. These jacks are, to put it bluntly, JUNK... they are EASILY damaged by pulling the cable plugged into them sideways. You will need to service the unit.
That was not I. I appreciate the link. Take care.
