Removing the Speakers
You have to remove the main bracket, but do not have to remove the power supply* or main board to remove the
speakers.
* For the 32-inch model, you must remove the power supply to remove the speaker.
To remove the speakers without removing the power supply or main board, remove the screws that secure the main
bracket, lift the bracket up to gain access to the speaker cable, and then disconnect and remove the cable.
Note: The left and right speakers are not the same.
