Everything is hooked up but nothing is working. What should I do?
When you troubleshoot issues with a legacy video cable, there are some quick tests that you can
complete to rule out potential problems. You can test to make sure that the following
components are working correctly and are not the source of the issue:
 Video cable
 Video source
 Video destination
Note: When you are testing setup components, you should avoid using video adapters. For
example, if you are converting an S-Video source to composite for use with a composite TV, you
should use a composite source when you test the composite cables.
To test your setup components, try the following:
 Use the video cable, source, and destination in another setup to see if the problem is with
the components or the setup.
 Use a different video cable, source, and destination in your setup to see if the problem
persists. Ideally, you should test a component that you know works in another setup.
When you test your cable, it is recommended that you do the following:
 Test each cable individually.
 Use short cables when you are testing.
