Yes you can remove the top with just a screw driver, there are a lot of
screws to remove, and you have to remove some of the front panels, side
lock for rear door, etc. this will let you lift the top, but the flash
assembly will still be attached by wires, so just leave the wires alone,
they are long enough to allow you to lift the top away and get to the knob.
You can apply some high quality lubricant to the inside of the knob (I did
this, and it helped a NEWLY INSTALLED by Canon knob). note that the knob
is part of the top and will not come off. you must return the knob to the
same position it was in when you removed the top to permit it to engage
with the circuit board mounted switch parts still on the body. (suggest you
start with body in OFF position) And remove the battery. You CANNOT get
to the detent ball, as it is part of the knob unit and not accessible
without breaking the knob assembly.
An ice cube tray is good for putting the screws into, keep track of where
each type is removed from, and keep them in sets relating to the cover or
component you removed them from. Some covers have long and short screws,
so note where they go.
good luck
