MAINTENANCE

CABINET CLEANING

•Wipe the front panel and other exterior surfaces of the TV with a soft cloth immersed in lukewarm water and wrung dry.

•Never use a solvent or alcohol. Do not spray insec- ticide liquid near the TV. Such chemicals may cause damage and discoloration to the exposed surfaces.

LCD CLEANING

Wipe the LCD of the TV with a soft cloth. Before cleaning the LCD, disconnect the power cord.

SERVICING

Should your unit become inoperative, do not try to correct the problem yourself. There are no user ser- viceable parts inside. Turn off the TV, unplug the power cord and call our toll free customer support line found on the cover of this manual to locate an authorized service center.

IR SIGNAL CHECK

If the remote control isn’t working properly, you can use an AM radio or digital camera (including a cellu- lar phone with built-in camera) to see if it is sending out an infrared signal.

• With an AM radio:

Tune the AM radio station to a non-broadcasting frequency. Point the remote control towards it, push any button and listen. If the sound from the radio flutters, it is receiving the remote control’s infrared signal.

•With a digital camera

(including built-in cell phone cameras): Point a digital camera towards the remote control. Push any button on the

remote control and look through the digi-

tal camera. If the infrared light appears

through the camera, the remote control is working.
