I have been in communication with Pentax USA trying to get my MZ-5n pop-up flash fixed. I am a DIY kind of guy so I already has the top off of the camera and figured out what was broken. I called the 800 number, got a parts rep who then e-mailed me the parts list/diagram. I e-mailed back with the part number that I needed and asked how to order it. Received an e-mail back saying send your address and we will send a couple of replacement parts, No Charge!!!
I was blown away to be able to get the parts, let alone at no charge. Two big thumbs up from me for the parts department at Pentax USA.

Anyway, just wanted to relay my experience.
