Remedy
The subwoofer and the front speakers in this system are magnetically
shielded to prevent magnetic leakage. However, some leakage may occur,
as a high-strength magnet is employed. If this happens, check the following
items:
• If the speakers are used with a CRT-based TV or projector, install the
speakers at least 0.3 m (1.0 ft) from the TV set.
• If the color irregularity persists, turn off the TV set once, then turn it on
after 15 to 30 minutes.
• If howling occurs, reposition the speakers further away from the TV set.
• Make sure that no magnetic object (magnetic latch on a TV stand, health
care device, toy, etc.) is placed near the speakers.
Remedy
• The speaker cord is not connected securely.
• Press MUTING on the remote if "MUTING" is displayed on the front
panel display.
• The system is in pause mode or in Slow-motion Play mode. Press H to
return to normal play mode.
• Fast forward or fast reverse is performed. Press H to return to normal
play mode.

• The HDMI OUT jack is connected to a DVI (Digital Visual Interface)
device (DVI (Digital Visual Interface) jacks do not accept audio signals).

connected component off and on again. 3 Disconnect and then connect
the HDMI cable again.

securely.
