Troubleshooting
If you have difficulty with your digital TV set-top receiver, there are several possibilities you
should investigate before calling for a service technician.
Problem
Intermittent signal, or no signal
at all.
Poor sound quality, or no
sound.
No color, or wrong colors.
Remote control doesn’t work
correctly.
The DTV set-top receiver won’t
turn on.
Possible Solution
Try another channel.
Make sure the antenna is connected.
If a powered antenna, turn the power boost on.
You may also want to rotate the antenna for a
stronger signal, using the tri-state LED indicator on
the front of your tuner as a guide.
Make sure audio connections are correct.
Try another channel - sometimes broadcasters
have problems with DTV audio encoding.
Make sure the MUTE button on your TV is off.
Try both analog and digital (coaxial, optical)
audio connections.
Make sure you have connected the DTV set-top
receiver correctly to your DTV-ready or analog TV
set.
For a three-wire component connection, match the
red, green, and blue cables from the set-top
receiver to your TV.
Make sure you have fresh batteries installed the
correct way in your remote. Also, select the correct
remote command mode to DTV or STB.
Make sure the receiver’s power plug is installed
and that the AC outlet is working.
Check the batteries in the remote control to make
sure they are fresh and installed correctly.
