Solution
• check that the receiver's power cord is properly plugged into the receiver's ac
power connector.
• check that the power cord is plugged into a working ac outlet. If the outlet is
controlled by a switch, make sure the switch is set in the "on" position.
• check that the receiver's Main power switch (located on the rear panel) is in the
"on" position.
• check the HDMI connection between the receiver and the tV.
• check the HDMI connection or component Video connection between the source
device and the BDS receiver.
• check that the tV is turned on and is set to the proper input source.
• unplug the HDMI cable from the tV and plug it back in again.
• check that the subwoofer's power cord is plugged into a working ac outlet.
• check that the subwoofer's power switch is in the "on" position.
• check that the Subwoofer Level control is not turned all the way down (fully
counterclockwise).
• check that the audio connection between the receiver and the subwoofer has been
properly made.
• check the receiver's Settings: Configuration menu to make sure that the subwoofer
volume has not been set at –10dB.
• check that all input cables are plugged all the way into their connectors.
• check that all cables are at least 10 ft (3.3m) from fluorescent lights.
• check that all cable connectors are clean. If necessary, wipe them with a cloth
slightly moistened with alcohol.
• Set the subwoofer's power switch to "off." If the hum goes away, there is a ground
loop between the subwoofer and the receiver. plugging the subwoofer's power cord
into the same ac outlet that the receiver is plugged into should eliminate the ground
loop.
• check that the disc is inserted correctly (label side up).
• check that the disc is the correct type: BD-Video (single-layer or double-layer),
DVD-Video, DVD+r/+rW, DVD-r/-rW, cDDa (cD digital audio), cD-r/rW. other
disc types will not play.
• check that the disc surface is clean and not scratched.
• check that the disc surface is clean and not scratched.
• press the options button and perform the Lip Sync adjustment to bring the sound
and picture into synchronization.
• check that the fM antenna is correctly connected.
• adjust the antenna's position. If necessary, use a powered fM antenna or an
outdoor fM antenna.
• replace all three remote-control batteries with fresh ones, and make sure that they
are installed with the correct polarity.
• Hold the remote closer to the receiver.
• check that the receiver's remote sensor is in the line of sight of the remote control.
• check that you have pressed the remote's aux button before trying to operate the
component.
• re-program and/or re-teach the component's commands into the remote.
• the selected function is not permitted at the time the button is pressed.
• unplug the receiver's power cord from the ac outlet, wait 30 seconds, then plug
it back in.
