Originally posted by krgroothuis I hope the ones that are fixed by repairshops get the white solenoid type used in the older camera's . K-x and before.
Normally Pentax official repair partners usually get only a new green one (made in China).
The repairshops never use the white one because they can't get it new.
The green one possibly costs "them" 1-2 dollars so why should they:
- invest about 30 min. time to disassemble an old *ist/K100D/Kx etc including testing the solenoid?
- spend the money for an old DSLR body?
when they can have it the cheap way?
Some even modify the green solenoid!
Originally posted by robtcorl I do see an ad for fixing the 30, 50, et al for $100, guess I'll have to do that if/when it gets worse.
This is photolab35 in California. He does the grinding/filing job and what comes out you can see here:
Solenoid problem return plus sound - Page 2 - PentaxForums.com
But it can happen worse, I have seen this to happen:
The white wheel got blocked because the filed/sanded plunger in this green China solenoid jammed and thus the spring "jumped out".
This then means a lot of work because one needs to exchange the complete diaphragm block:
Pentax 77860-G0100 Diaphragm Control Block | K-S2 | K-30 | K-50 | PartsUSCamera
Then a good solution is to swap the green China-solenoid on this block against the
white Japan version
because often the
green bugger sticks again.
