Troubleshooting
This section gives recommendations on what to do if you have problems
operating the DVS 406, and it provides examples and descriptions for some
image problems you might encounter.
The following are some tips to help you in troubleshooting.
1. Some symptoms may resemble others, so you may want to look through all
of the examples before attempting to solve the problem.
2. Be prepared to backtrack in case the action taken doesn’t solve the problem.
3. 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.
4. Try simplifying the system by eliminating components that may have
introduced the problem or made it more complicated.
5. For sync-related problems: Portable digital projectors are designed to
operate close to the video source. 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.
6. 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”.
