Proj-or-View problems

>>In the unit that I sold [TDC Projector-or-View] I noticed that there was considerable slack in the focusing control.  Is that normal?  Any way to fix it?

George my boy...sure you can fix it!  The Proj-or-View is a poor quality
projector with a poor quality viewr, but you can make it a bit better.

   First turn it upside down--see those 20 or so screws in two rows?
They all come out, then the top and bottom halves of the unit come apart
(two metal strips held the pieces together, thanks to all of those
screws).
   Next, look for the junky little lenses--they're in a metal holder
that uses a band and springs to return the interocular..the grease
always gums up. Take the lenses out--clean them and the metal plate, and
re-lubricate with something that can't freeze up. Now look for the focus
knob and clean and re grease that. This is where I usually force the
small lens up out of position (this is a depolarizer that is turned into
the path of the light if you don't want the 3D effect--duh). 
   Clean and lube whatever else moves, replace or at least clean all of
the polarizers and mirrors, and then replace the lenses and lens
assembly. Oh, did I mention that you really should pull the fan blades
off the shaft to make it easier to separate the unit???
   Now hold it together (but don't actually reassemble it) so that you
can try to focus the lenses manually on the screen, because you
unscrewed them and you'll need to reset the focus. Once you figure
everything is okay, put the fan blade back on, slide the metal strips in
place, and try to get all the screws back in.
  Presto--just as easy as that, you're done!

That's why I sell Projector-or-Views cheaply, so the buyer can take a
few days off work to clean and relube the insides themself.
