Troubleshooting
What happens if the projector does not go on even when I
know the power outlet works?
There is a fuse on the back of the projector that may break if the projector is
dropped or handled improperly. If the projector fails to turn on, replace the
fuse with one from the accessory box.
What happens if I turn on the daily motion switch and the
cylinder doesn’t rotate?
First check to see if the large rectangular plug is securely attached to the
back of the projector. If so, check and see if the belt that drives the cylin-
der at the base of the projector is tight. It may have become stretched or it
may have broken. In either case, a replacement belt can be ordered from
Science First/STARLAB. After many years of use, it is possible that the motor
may burn out. A replacement motor can be ordered from Science First/
STARLAB. (Part # SL-153).
What happens if I’m missing some light blocks for the
Starfield cylinder?
Spare light blocks are included in the accessory box and new light blocks
can be ordered from Science First/STARLAB. DO NOT USE adhesive
backed dome patches or tape to cover the light ports on the Starfield Cylin-
der!
What happens if I change the projection bulb on the Stan-
dard Projector and it still does not light?
While it is possible that the replacement bulb is burned out, it’s not usually
the case. First try using another replacement bulb. If it still does not work,
make certain that the 1/4 inch phone plug at the back of the projector and
the two “banana plugs” near the top of the projector head are both securely
plugged in. On rare occasions, the wires leading to the “banana plugs” can
get pulled out. If they do, you must remove the plug, unscrew it and replace
the wire.
What happens if I see “stars” shining through the dome
even when the projector is turned off?
The extra stars are really tiny holes in the dome. They can be easily patched
by using the pre-adhesive peel-and-stick dome patches included in the acces-
sory box. Extra dome patches can be ordered from Science First/STARLAB
See the section on dome maintenance (page 31) to learn the proper proce-
dure for patching the dome.
