A APPENDIX 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. 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. Poor sound quality, or no sound. 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. No color, or wrong colors. 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. Remote control doesn't work correctly. Make sure you have fresh batteries installed the correct way in your remote. Also, select the correct remote command mode to DTV or STB. The DTV set-top receiver won't turn on. 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. A.1
