TROUBLESHOOTING Problem Cause There is noise interference from digital or highfrequency equipment, or this unit. This unit is too close to digital or highfrequency equipment. The picture is disturbed. The video source uses scrambled or encoded signals to prevent dubbing. This unit suddenly switches to the standby mode. Monitor output fails. The internal temperature has become too high and the overheat protection circuitry activated. The wrong TV format is set. ■ Tuner Remedy Move this unit further away from such equipment. Playing back video software that has an anti-copy signal or video signals with a lot of noise may produce unstable images. Wait until this unit cools down and then turn it back on. Press and hold down EXIT on the remote control for 5 seconds or longer to initialize Video settings. Refer to page - - - 78 Problem FM stereo reception is noisy. There is distortion, and clear reception cannot be obtained even with a FM good FM antenna. The desired station cannot be tuned in with the automatic tuning method. Previously preset stations can no longer be tuned in. The desired station cannot be tuned in with the automatic tuning method. There are continuous AM crackling and hissing noises. There are buzzing and whining noises (especially in the evening). Cause The characteristics of FM stereo broadcasts may cause this problem when the transmitter is too far away or the antenna input is poor. There is multipath interference. The station is too weak. This unit has been disconnected for a long period. The signal is weak or the antenna connections are loose. Noises result from lightning, fluorescent lamps, motors, thermostats and other electrical equipment. A TV set is being used nearby. Remedy Check the antenna connections. Try using a high-quality directional FM antenna. Use the manual tuning method. Adjust the antenna position to eliminate multipath interference. Use a high-quality directional FM antenna. Use the manual tuning method. Preset the stations again. Tighten the AM loop antenna connections and orient it for the best reception. Use the manual tuning method. Use an outdoor antenna and a ground wire. This will help somewhat, but it is difficult to eliminate all noise. Move this unit away from the TV. Refer to page 28 48 - 28 48 49 - 48 - - 118
