No remote control operations can be performed.

Check whether the batteries have discharged completely and, if they have not, whether they were

 

 

 

 

 

 

inserted properly.

 

 

 

 

 

 

Check whether the remote control sensor is exposed to an outdoor light or a strong uorescent light.

 

 

 

 

 

 

Check whether the remote control designed specically for use with the unit is being used. (The unit

 

 

 

 

 

 

cannot be operated by any other remote control.)

A cracking sound is sometimes heard from the unit.

If there is nothing wrong with the picture or sound, this is the sound of the cabinet undergoing

 

 

 

 

 

 

very slight contractions in response to changes in the room temperature. There are no adverse

 

 

 

 

 

 

effects on the performance or other aspects.

I can hear sounds coming from inside the unit.

When the power is turned on, a sound of the display panel being driven may be heard: This is

 

 

 

 

 

 

normal and not indicative of malfunctioning.

Parts of the unit become hot.

 

Even when the temperature of parts of the front, top and rear panels has risen, these temperature

 

 

 

 

 

 

rises will not pose any problems in terms of performance or quality.

Power automatically turns off unexpectedly.

Check the settings of “NO SIGNAL POWER OFF”, “PC POWER MANAGEMENT”,

 

 

 

 

 

 

“DVI-D POWER MANAGEMENT” and “NO ACTIVITY POWER OFF”. Any of them may be

 

 

 

 

 

 

set to “ON (ENABLE)”. (see page 34, 35)

There is no picture displayed or sound output

This LCD Display uses special image processing. Hence a slight time lag may occur between image and audio, depending on the type of input signal. However, this is not a malfunction.

Image retention may occur. If you display a still picture for an extended period, the image
