Pentax MX stuck shutter


I've ecountered some problems with my MX. Its shutter is stuck in cocked position (the indicator near the shutter button is red). Mirror is down and I can push the shutter button all way down and nothing happens and can not wind of course.

In the attachment is the MX without the botton cover.

BTW, how can I take down the top cover?, especially how to dismantle de shutter times dial (at what should I care more, are there some setttings I should remeber, before dismtle the dial? etc?)

Thank you very much.

I can't help with any disassembly but Eric has done wonders with my film bodies.

This is how a working MX bottom should look like. Pardon the large image, but it's in the interest of better sight

Also be sure to read this: Jammed Spotmatic. Sure, not the same camera, but it may help nevertheless.
To get the top cover off, you need a pointed tip lens spanner.

To see better, you should get under the low speed assembly.

So... in your image I marked where you should look...

The screw head with a roller sleeve as circled, an arm is supposed to push it to the reset position. With the low speed assembly out of the way, you'll have good look at it.
