That's pretty much what I figured. I took a closer look at one of the
other dead XT2190s I have that I'd opened up to inspect awhile back and
there are a few ICs surface-mounted to the flat ribbon cable running to
the head assembly. I suppose it's likely that one of these has failed,
though actually repairing it would be a trick involving some very
careful disassembly in a very clean environment. (And a nonexistent
service manual.)
