Troubleshooting

This paragraph gives recommendations on what to do if you have problems operating the scaler, and it provides examples and descriptions for some image problems you may encounter.

The following tips may 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 does not 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”.

2.

Ensure that the input selected is active.

Check the cabling and make corrections as necessary.
