Possible Remedies
❏
The batteries could be weak. Replace the batteries.
❏
Check the orientation of the batteries.
❏
Press TV (FUNCTION) once, and the TV indicator lights up. You may have
inadvertently pressed SAT/CABLE (FUNCTION), which changes the remote
control to SAT or CABLE mode.
❏
Make sure this unit's power cord is connected securely to the wall outlet.
❏
Install the unit at least 3-4 feet away from fluorescent lights.
❏
If the "High Temperature Warning!" message appears, turn off the TV and wait
until the TV's projection lamp cools down (approximately 5 minutes). If the
remote control still does not work, make sure to dust the ventilation slots on the
rear of the TV and the cooling fan to provide adequate ventilation around the TV.
❏
If you are using the TV to change channels, first press TV (FUNCTION) once,
and the TV indicator lights up.
❏
If you are using another device to change channels, be sure you have not
inadvertently switched your TV from the channel 3 or 4 setting.
❏
If you are using another device to change channels, be sure to press FUNCTION
for that device. For example, if you are using your cable box to change channels,
be sure to press SAT/CABLE (FUNCTION) once, and the SAT/CABLE indicator
lights up.
❏
If you replaced the batteries to the remote recently, the code numbers for the video
equipment may need to be reset.
❏
There may be more than one code for the equipment that you are attempting to
operate.
❏
There is a possibility that some non-Sony equipment cannot be operated by your
Sony TV remote. You may need to use the equipment's original remote control.
Possible Remedies

Check the Diagnostics and CableCARD setting options (see page 84). (This can
be useful in providing information to an authorized technician or repair person.)
