Troubleshooting
Warning: Do not try to repair your TV combo yourself. Refer all servicing to qualified service
personnel. Do not remove the back cover. Your TV combo has dangerous electrical
voltages inside that may cause a fire or injury.
Note: Your TV combo may make occasional snapping or popping noises. This is caused by
materials in the cabinet expanding or contracting when the room temperature changes.
