<p>95% chance the mirror unglued itself, this is what happened on mine, I look through the finder, and can't see the patch - there are 2 possibilities: no mirror, or someone wiped off the beam splitter's silver layer (possible but unlikely as it seems to be a large unit of glass).<br> Remove the back plate, rotate the film takeup spool so that the open notch exposes a screw, undo it, the other screw will be near the film compartment.<br> Then the top plate should lift, unscrew the plunger's cap (might take some force), and carefully lift the top plate - it will take you some wiggling as the focusing knob is holding it.<br> Once the plate is off, you will see the RF unit (angled), the half-mirror if unglued should fall out so don't lose it.<br> Unscrew the RF unit (2 screws, bottom left and top maybe 1 cm from the left), it will come out.<br> The mirror should be glued at a 45 deg angle on the back behind the diamond/square window - you would see where.<br> Once it's in place you're up for quite some work to adjust the RF patch again.<br> In my model (square patch, nearly the latest vitessa L), the vertical was very off after fixing the mirror, I had to turn the hex screw on the top of RF unit to move the beam splitter enough to bring the patch in-line. I haven't done the horizontal alignment yet.</p> <p>Putting the plate back on requires you to kind of do it upside-down (watch out for the shutter release shaft), and when the plate is on, you need to move the lens bellows a tad so that the focusing knob goes all the way where it should.<br> The sprint that might fall out should go between the knob and the round top plate.<br> Have fun.</p>
