Hi @keyboardman101,
 
You can use the manual but you’ll have to work out the circuit path from the reristorreistor supplying the power for the notes (keys) in question to the keysquestion.

If you click on the magnifying glass in the image above and then click on the enlarged image again you’ll get a better view of the keys and the musical notes that they are used for.

Download the manual using the link in the answer above and find the schematic which shows the keys as shown in the image above.
 
I don’t know music at all but when you find your key contact by its’ musical note designation, trace the wiring through the circuits back to a supply resistor on the DMLCD board. The wires are numbered to make it easier to follow through the circuit.
 
There will be a problem somewhere along this path, perhaps at the resistor or maybe a connector plug that is not quite pushed in properly.
 
The path will be different to what is described in the answer above because the notes are different in your case, but the principle of how they work is the same.

Good luck.
