TV Reset Comparison Guide
You can resolve many common TV problems using the
reset functions described in the following table.
IMPORTANT
Before you change sound or picture settings: If
picture or sound settings seem wrong for a broadcast
channel (a channel from the ANT input, 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 channels also affect all other
channels on the same input.
