Troubleshooting (Continued) Antenna Problem The picture is not sharp. The picture moves. The picture is doubled or tripled. The picture is spotted. There are stripes on the screen or colors fade. Check item • The reception may be weak. • The quality of the broadcast may also be bad. • Make sure the antenna is facing the correct direction. • Make sure the outside antenna is connected. • Make sure the antenna is facing the correct direction. • There may be reflected electric waves from mountains or buildings. • There may be interference from automobiles, trains, high-voltage lines, neon lights, etc. • There may be interference between the antenna cable and AC cord. Try positioning them further apart. • Is the unit receiving interference from other devices? Transmission antennas of radio broadcasting stations, transmission antennas of amateur radios and cellular phones may also cause interference. • Use the unit as far apart as possible from devices that may cause possible interference. ■ Cautions regarding use in high and low temperature environments • When the unit is used in a low temperature space (e.g. room, office), the picture may leave trails or appear slightly delayed. This is not a malfunction, and the unit will recover when the temperature returns to normal. • Do not leave the unit in a hot or cold location. Also, do not leave the unit in a location exposed to direct sunlight or near a heater, as this may cause the cabinet to deform and the LCD panel to malfunction.
