HT-S3910 - Troubleshooting: Tuner/Radio

Problems may be solved by simply turning the power on/off or disconnecting/ connecting the power cord, which is easier than working on the connection, setting and operating procedure. Try the simple measures on both the unit and the connected device. If the problem is that the video or audio is not output or the HDMI linked operation does not work, disconnecting/connecting the HDMI cable may solve it. When reconnecting, be careful not to wind the HDMI cable since if wound the HDMI cable may not fit well. After reconnecting, turn off and on the unit and the connected device. 

• The AV receiver contains a microPC for signal processing and control functions. In very rare situations, severe interference, noise from an external source, or static electricity may cause it to lockup. In the unlikely event that this happens, unplug the power cord from the wall outlet, wait at least 5 seconds, and then plug it back in.

Try restarting the unit

Restarting this unit may solve the problem. Set the main unit to standby, then after waiting for 5 seconds or more, press and hold the ON/STANDBY button of the main unit for at least 5 seconds, and then restart the unit. (The settings on this unit are kept.) If the problem persists after restarting the unit, unplug and plug the power cords or HDMI cable of this unit and connected devices.

Resetting the unit (this resets the unit settings to the default)

If the restart of the unit does not solve the problem, reset the unit, and restore all the settings to the factory default at the time of purchase. This may solve the problem. If the unit is reset, your settings are restored to the default values. Be sure to note down your setting contents before performing the following operations. 

1. While pressing and holding CBL/SAT of the input selector on the main unit with the unit turned on, press the ON/STANDBY button. 
2. "Clear" is displayed on the display, and the unit returns to the standby state. Do not remove the power cord until "Clear" disappears from the display.

Poor reception or noise

• Recheck the antenna connection.
• Move the antenna away from the speaker cord or power cord.
• Move the unit away from your TV or PC.
• Passing cars or airplanes in the vicinity can cause interference.
• If radio waves are blocked by concrete walls, etc., radio reception may be poor.
• Change the reception mode to mono.
• Operating the remote controller during AM reception may cause noise.
• FM reception may be clearer if you use the antenna jack on the wall used for the TV.
