There is no sound in HDMI mode. Displayed picture colours may not look normal.
Video or sound may not be available. This can
occur if a source device that only supports an
older version of the HDMI standard is
connected to the product.
If these issues occur, connect an audio cable
along with the HDMI cable.
Some PC graphics cards may not
automatically recognize HDMI signals that do
not include sound. In this case, manually select
a sound input.
The IR sensor is not functioning. Make sure the sensor light turns on when a
button is pressed on the remote control.
If the sensor light does not turn on, turn the
power switch off and then on again on the
back of the product.
(The power LED lights up red when the
screen is switched off.)
If the sensor light still does not turn on after
the power switch is turned off and then on
again, an internal jack may be
disconnected.
Contact your nearest service centre to have
the product serviced.
If the sensor light that is on does not flash
red when a button is pressed on the remote
control, the IR sensor may be defective.
Contact your nearest service centre to have
the product serviced.
If there is no change on the screen when a
button is pressed on the remote control
although the sensor light flashes red, the
mainboard may be defective.
Contact your nearest service centre to have
the product serviced.
