It
is very likely that an integrated circuit or some such impossible
electronic part is zapped or broken forever and you shouldn't waste
your valuable time on such a trivial problem. However, if you are
a victim of your urge to fix such things, like myself here are some
guidelines.
Phase 1
* visual inspection
* look for loose connections or cracks in anything
* check to make sure all the screws are tight enough
(Sometimes a loose screw is part of an electrical connection)
* use air to clean out any dust or other obstructions to sensors
* make sure all the rollers roll the correct way and work
Phase 2
* find your digital camera
* take pictures as you go along to remember how to put it back together
* tape screws near where they go after taking them out so you don't
forget where they go
* try to find out how to take it apart -- manuals are very handy for
this
* be very careful with laser assemblies - if it goes out of alignment
the game is over
* look for broken things
* try to fix broken things
Phase 3
* put things back the way you found them except for the parts you
fixed.
