<p>I know it's years later, but this thread helped me fix the same problem with my Sears KS-2, which is the same camera, rebadged.</p>
<p>I took off the bottom plate, looked around for something that looked like the pin mentioned earlier, and guessed right at which thing it was. I moved it so that the winder would move freely, and wound 4-5x, and the stuck mirror came back down. I moved the pin back and fired the camera a bunch of times; looks good. </p>
<p>Here's hoping the problem doesn't recur, but at least I know how to reset the mirror now.</p>
