Quite likely the plastic pin which holds the spring is broken. You can
either drill a hole and install a brass pin yourself, or have that part
replaced by Pentax.

The retractable flash on my Zx-5n seems to have lost it's spring. It pops
up,
but no longer locks in the "up" configuration - a not unheard of problem.
For
the folks who have experienced this before, what did you do to fix this
problem
(besides using a shoe flash)? I am not a mechanically able person. Is this
something that Pentax-Colorado fixes and what might it cost?
