Player piano problem

"Not working"   hmmmm  Assuming they work when played by hand
there are two branches off the flow chart...

When the player is engaged, do the hammers stay off the rail.
That usually is a leak between the tracker bar and valve, 
dislodged/split tubing,
loose valve fitting  or stuck-open valve.

When the player is engaged, the note does not play when signalled... 
valve failure,
torn/porous cloth on pneumatic, dislodged pneumatic, clogged bleed (maybe more
sluggish). stuck-closed/dislodged valve.

What brand of player, what type of stack?
Here's one for ya... Are there primary valves?
Is the roll tracking properly, that will cause 'missed notes'.
