Problems and solutions
• If the picture output from your system goes through your VCR to get to your
TV, the copy-protection signal applied to some DVD programs could affect
picture quality. Connect the unit directly to your TV.
• Check the setting of [TV TYPE] in [VIDEO SETUP] (page 55).
• The aspect ratio on the disc is fixed.
The system's speakers contain magnet parts, so magnetic distortion may occur.
When color irregularity occurs on the TV screen, check the following items.
• Install the speakers at least 0.3 meters (1.0 ft) from your TV set.
• If the color irregularity persists, turn off your TV set once, then turn it on after
15 to 30 minutes.
• Make sure that no magnetic object (magnetic latch on a TV stand, health care
device, toy, etc.) is placed near the speakers.
• Reposition the speakers farther away from your TV set.
• Set [YC C ] in [YC C /RGB (HDMI)] to [RGB] (page 57).
