Try playing the first test on the alignment tape- the one that simply strikes each note a few times going up the keyboard. Keep track of which notes play and which don't. The note solenoids are driven by three separate driver boards: a 32-note bass board, a 16-note center board, and a 32-note treble board (the treble and bass boards are identical). Does it seem like notes on only one of the boards are failing? With the piano unplugged, it couldn't hurt to try reseating the connections. Also, I've found that the power jack on the driver boards (accepting the red/black cable) is often not soldered well and occasionally works loose from vibration, resulting in intermittent playback. Be sure the Pianocorder is unplugged before handling any internal components!
