• Check that the power plug is securely inserted into both
the AC-IN socket on the display and the wall outlet.
• Check that the equipment connected is working properly.
• Check that the display is powered on.
• If the display is connected to a PC, press any key to wake
the PC up from standby.
• Check to make sure that the headset is not connected.
• Check the settings in the Sound menu.
The display may be receiving interferences from other
home appliances or cars..., etc. Try moving the display to a
different location.
• Make sure that all signal cables are firmly and correctly
connected to the display.
• Change the Color Temp setting to its default value.
• Make sure that all signal cables are firmly and correctly
connected to the display.
• Make sure that the input signal resolution is supported by
the display.
• Check the resolution of the signal on the output device to
make sure that it is supported by the display.
If the display is displaying VGA input signal, make sure
that the Horizontal and Vertical settings in the Picture
menu is appropriate.
• Check the volume setting.
• Check that the mute function is not activated.
• Check that all signal cables are firmly and correctly
connected to the display.
Your display is manufactured using high precision
technologies. However, some pixels (dots) on the screen
may not display and remain permanently bright or dark.
This is considered a normal phenomenon of the LCD
technology and not a defect.
This usually happens when the resolution of digital input
signal exceeds that supported by the display. Change the
signal resolution on the output device and try again.
