Exactly.
And they would not be able to do this for the offered price.
Replacing the green solenoid with a new one would be a foolish solution because the ones available from China are the ones that fail.
Because several of those repaired DSLR had to be sent back again it is most obvious that he does exactly what he writes:
This repair includes a modification of the aperture control block in order for it to function properly. We believe this should be a permanent fix of the aperture control block and we will guarantee proper aperture function for one year. If the aperture block fails again, return the camera to us and we will repair it again. You'll only pay return shipping. Having your aperture control block replaced by Pentax may not guarantee it won't fail again. This part appears to fail over time and use.
As I have done enough research and tests concerning the aperture control block and the solenoid, it is obvoious to me that what he does is NOT replace the solenoid with the green Chinese one:
Because this would not be a modification!
Nor does he replace the bad one with the Japanese white solenoid because he would have to charge more and would mention this (everybody would go for this repair
So if one knows about the shutterproblem one can say for sure that there are only two other options:
- sand the plunger
or
- apply solder to the plunger
Both are not the best solutions, I have explained often enough why. Yes, they work, but both are risky.
The soldering version would be the worse of those two options (and much more work involved)
This is because the length of the plunger is altered, the action of the mechanism is different!
