Various reasons can cause noise interference to the sound from the subwoofer or rear speakers. Please try the following solutions:
- Move away from devices that interfere with wireless communication.
If near a device that emits electromagnetic waves such as a wireless LAN router or microwave oven, move away from the device.
- Do not place obstructions between the unit and the subwoofer or rear speakers.
If there is metal, concrete, or plaster between the unit and subwoofer, avoid or remove the obstructions.
- Place the unit, subwoofer, and rear speakers in close proximity to one another.
Place the unit and subwoofer as close as possible.
- Use a wired connection instead of a wireless connection.
Switch the TV and Blu-ray Disc recorder from a wireless LAN connection to a wired LAN connection.
- Select Off or On for RF Channel. Try the following setting.
- Press HOME.
- The home menu appears on the TV screen.
- Select Setup - Advanced Settings on the home menu.
- Select Speaker Settings - Wireless Speaker Settings.
- Select Off or On for RF Channel.
- When you change the RF Channel settings, it may take 1 minute to reconnect.
- The frequency setting is deleted if the power cord is disconnected. If the power cord is disconnected, switch RF Channel from Off to On again.
- The RF Channel default setting is On. When the setting is on, the system automatically selects the best channel for transmission. This mode is stronger against wireless interference. If sound still drops while the setting is set to On, setting it to Off may improve the issue.
