TV Reset Functions
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 chan-
nels 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.
