Hi,
I recently bought the K30 body, it was supposed to have the "dark photos syndrome". I had read about it before on the forum and saw some tutorials on YT.
And I found it interesting. So I decided to have some fun and try to fix it. Reality turned out to be a little less bright
.
When the body arrived, some more problems showed up.
Thanks to this, the project "for fun" turned out to be even more interesting.
I did some testing and what do I know so far:
1. the previous owner tried to repair the solenoid by himself with the "grinding method", and failed.
2. black pictures instead of dark
3. mirror blocked on top
4. shutter does not fire
5. the camera starts up, the buttons work, the screen looks good
6. the mode selector wheel operates randomly (dial on the top) /
after cleaning and reinstalling the ribbon cable it started working properly
7. the memory backup battery looks almost dead, the camera quickly forgets the settings (time), after removing the main battery
8. firmware v1.10 first version, the camera identifies itself as K50 /
downgrade to oryginal v1.06 + debugging, no improvement
9. the adjustment wheels work strange, not always (I need to do more tests to figure it out) /
fixed after unlocking the solenoid and setting the focus switch
10. sometimes the camera won't turn off and you need to remove the battery.
11. aftermarket battery /
I don't see any impact on the camera's work
12. focus mode selector is not assembled properly (wrongly positioned) /
works fine after reinstallation
13. mess with screws /
solved thanks to pictures shared by photogem in this topic -> Length of screws in K30, K50 and K500 - PentaxForums.com
and that's all I have found for now, if there is more, I will complete the list
I didn't open camera yet.
I have bought a donor for solenoid (*istD) and I am gathering the information about possible solutions to this issues.
Except the testing, I have flashed the orginal firmware from pentax v1.06, and I did debugging. No changes by now.
I've tryed adapter 4xAA with fully charged Varta (Ready to go 2600mah), but K30 the camera says the voltage is too low (they are not brand new). I've insert oryginal battery from my other pentax, but it didn't change much ( as far I can see)
I've managed to shoot some pictures befere mirror and shutter got stuck, they where completly black, shutter counter is around 60k.
Well, yes, the list is quite long, probably some will say "recycle it" and probably it will be the best solution in this case.
But I like to fix things, and I want to give this camara a chance.
I have been reading in recent days about the problems with the K30. And I wonder where to start.
I guess I should have replaced the solenoid first and set the focus selector
I think I can find more interesting things inside
Please write if you have any tips on this case.
But please, no tips like "throw it away", i mean for now, before I even try, maybe later
