Hi, sorry to put back to life this very old thread, but it seems I "screwed it up", literally.
Basically yesterday I opened the hot shoe, and fiddled with the vertical alignment screw on my RD1s (yes, the big right one, above the other two, can't be wrong on this).
Screw was very loose, and I turned it CCW in order to get the patch a bit up, but at the beginning nothing happened.
then I think I somehow overshoot it and got the screw turning too much, now patch is like more than double its height ABOVE the subject.
Trying to close back the screw turning CW only make it go till the end when it's tied up, but not changing the patch position any more.
What happened exactly? 🙁
