Troubleshooting
This section gives recommendations on what to do if you have problems operating
the transmitter/receiver system, and it provides examples and descriptions for
some image problems you may encounter.
The following tips may help you in troubleshooting.
• Some symptoms may resemble others, so you may want to look through all
of the examples before attempting to solve the problem.
• Be prepared to backtrack in case the action taken does not solve the problem.
• It may help to keep notes and sketches in case the troubleshooting process
gets lengthy. This will also give you something to discuss if you call for
technical support.
• Try simplifying the system by eliminating components outside the system
that may have introduced the problem or made it more complicated.
• For sync-related problems: Portable digital projectors are designed to operate
close to the immediate video source (the receiver). Sync problems may result
from using long cables or from improper termination. A sync adapter, such
as Extron’s ASTA (active sync termination adapter), may help solve these
problems.
• For LCD and DLP projectors and plasma displays: In addition to the sync-
related information above, check the user’s manual that came with the
projector for troubleshooting tips, as well as for settings and adjustments.
Each manufacturer may have its own terms, so look for terms like “auto
setup,” “auto sync,” “pixel phase,” and “tracking.”
General checks

receiver both have Power LEDs to indicate that power is applied.
2 . Ensure that the input selected is active.
3 . Ensure that the proper signal format is supplied.
4 . Check the cabling and make corrections as necessary.
5 . Reset the switcher. See “Full system reset” on page 3-5.
