If you have a problem...
If the screen display is not clear, try adjusting the controls on your
television set or monitor. You may not get a picture at all if your control
settings or connections are not correct. In such a case you should
check all your settings and connections. Often the TV may simply be
tuned to the wrong channel, or you may have the brightness turned
off.
The Troubleshooting Chart shown on the following page lists some
of the more common problems and tells how to correct them.
