DDS 100 Troubleshooting 6-2
This section gives examples and descriptions for some problems you
might encounter in using the DDS 100.
The “probable solutions” are listed for ease of implementation, as well
as the order of probability. For example, it’s easier to flip a switch than it
is to change cables, so you may want to try the switch first. It may be
easier to check cables and other devices than to go through a lengthy
convergence procedure, so you might check those components first.
Also, if an adjustment procedure doesn’t solve the problem, it may make
it more complex.
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 attacking 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 such as “auto setup”, “auto sync”, “pixel
phase”, and “tracking”.
