Troubleshooting
Possible Cause
• Check the aerial antenna connection. Make
sure that it is correctly and firmly
connected to the DTV tuner box.
• Not all digital TV channels are available in
your area. Please refer to
digital TV signals" on page 1
digital TV signal coverage in your area.
• The signal can be too weak to be scanned
and stored. Have a professional antenna
technician re-orient or re-locate the aerial
antenna, or use a signal amplifier to
strengthen signal reception.
• Signal reception may be too weak for the
pictures to be displayed.
• The signal may be too strong. If a signal
amplifier is used, try lowering the signal
strength to an appropriate level.
• There may be interference from other
devices, for example, a hair dryer or air
conditioner. Turn off these devices
temporarily and see if the problem can be
solved.
