If a pencil eraser helps to alleviate the problem it's probably some
kind of oxidation on the contacts.
Cleaning contacts with an eraser was what we used to have to do with our
radio handsets when I was in the Army. You couldn't see any difference
there either, but it worked & it was an approved maintenance procedure.

Alan,
I am not sure if this is related or not: With both K-7 and K-5iiS,
I experienced the same thing: over the time they both developed the
problem that the flash would not make a consistent contact. To make the
contact, I need to wiggle it around to find "the right position".
It looks like if I use something (e.g. a pencil eraser) to rub on the
contacts, the situation improves (it might be a placebo effect though),
even though I don't see any visual difference with the contacts.
The symptoms (when the flash does not have the proper contact) are that
the flash indicator in the view finder is not steady prior to the shot,
but blinking if the light is insufficient, as if no flash was attached.
The outcome is that the flash goes off, but TTL metering doesn't work.
Your situation might be different.

The K7 has a black anodised hot shoe (unlike the bare metal one on my
K110D). It is not obvious how an attached flash is grounded. I seem to
be having intermittent problems with a bad ground contact. Any comments?
