The color irregularity on a TV screen persists. •Turn off the TV set once, then turn it on after 15 to 30 minutes. If the color irregularity still persists, place the speakers farther away from the TV set. “PROTECT”and “PUSH POWER” appear alternately. •A strong signal was input. Press ?/1 to turn off the power, leave the system turned off for a while, then press ?/1 again to turn on the power. •Check the speaker cables in case “PROTECT” and “PUSH POWER” appear alternately again after you turn the system on. Speakers Sound comes from one channel or unbalanced left and right volume. •Check the speaker connection and speaker placement. Sound lacks bass. •Check that the speaker’s + and – jacks are connected correctly. CD Player The CD tray does not close. •The CD is not placed properly. The CD will not play. •The CD is not lying flat in the disc tray. •The CD is dirty. •The CD is inserted label side down. •Moisture condensation has built up. Remove the CD and leave the system turned on for about an hour until the moisture evaporates. Play does not start from the first track. •The player is in program or shuffle mode. Press PLAY MODE repeatedly until “PGM” or “SHUFFLE” disappears. “OVER” is displayed. •You have reached the end of the CD. Turn SHUTTLE counterclockwise. continued Troubleshooting (continued) Tape Deck The tape does not record. •No tape in the cassette holder. •The tab has been removed from the cassette (see “To save a tape permanently” on page 41). •The tape has reeled to the end. The tape does not record nor play or there is a decrease in sound level. •The heads are dirty. Clean them (see “Cleaning the tape heads” on page 42). •The record/playback heads are magnetized. Demagnetize them (see “Demagnetizing the tape heads” on page 42). The tape does not erase completely. •The record/playback heads are magnetized. Demagnetize them (see “Demagnetizing the tape heads” on page 42). There is excessive wow or flutter, or the sound drops out. •The capstans or pinch rollers are dirty. Clean them (see “Cleaning the tape heads” on page 42). Noise increases or the high frequencies are erased. •The record/playback heads are magnetized. Demagnetize them (see “Demagnetizing the tape heads” on page 42). Tuner Severe hum or noise (“TUNED” or “STEREO” flashes in the display). •Adjust the antenna. •The signal strength is too weak. Connect the external antenna. A stereo FM program cannot be received in stereo. •Press STEREO/MONO so that “MONO” disappears. If other troubles not described above occur, reset the system as follows: 1 Press x, ENTER and ?/1 at the same time. 2 Unplug the power cord. 3 Plug the power cord back in. 4 Press ?/1 to turn on the power. The unit is reset to factory settings. All the settings you made, such as the preset stations, clock, and timer are cleared. You should set them again.
