Repaired the built-in flash of a dropped K-x by myself. good news for some guys!

I recently repaired my K-X. After my white K-x dropped to the floor, the build-in flash can not pop up. but actually, it works well just can not pop up, which means I can't use the Av Tv Sv M P ... modes.
so I disassembled it, and shot the problem.
firstly, take all circled screws except the squared one

7 screws total, do not miss the last one under the battery
then, you will see sth like this:

English is my 2nd language, I will try to explain it clearly.
1. when I use any mode except no-flash mode, the flash works even it didn't pop-up. so I think there must be a sensor or something small setup to detect whether the flash was poped up.
2. the setup in the left side box (fig 3) is electromagnet, which can pull the hook (fig.2) then free the flash.
3. please notice the black cylinder in squared area of fig 4, 5. Principle is certainly a signal from the copper contacts to determine whether the flash pops up. in the process of the flash pops up, the coaxial rotating black plastic semi-cylinder (shown in fig 4, 5) adjusts the pressure on the copper contacts. So the flash pops up, the reed should be two different locations - contact and no contact.
