TV Reset Comparison Guide

You can resolve many common TV problems using the reset functions described in the following table. See also the additional troubleshooting suggestions later in this appendix.

IMPORTANT

Before you change sound or picture settings: If picture or sound settings seem wrong for a broadcast channel

(a channel from ANT 1, ANT 2, a cable box, or satellite receiver), first check other channels from the same input before changing settings. If most other channels from the same input seem correct, there is likely a problem with the broadcast rather than with the TV. Use care in this case, as changes you make to fix problems on individual chan- nels also affect all other channels on the same input.
