TV Reset Comparison Guide
You can resolve many common TV problems using 
the reset functions described in the following table. 
See also the 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 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.
