In the Sound settings turn the Bass up to 100% and the treble down to 0.
Then hold down the '-/v' button on the TV's front panel and press INDEX on the remote.
Be warned though, all your Picture settings for the channel you're on (Brightness, Contrast etc.) will be reset to their defaults every time you do this. So it's best to either do it on an input you don't use (like AV3) or change the Picture to a setting you don't use (like Dynamic). This way the settings for your primary usage mode will be preserved.
Once you're in service mode you can use the RED and GREEN fastext buttons to scroll through the available settings, and the YELLOW and BLUE buttons to alter the values. Pressing STR saves the changes for the setting you're on, and the N button exits and returns you to normal viewing mode.
