Troubleshooting
There are many external influences and circumstances beyond the control of
BenQ which may be causing problems with your display. Some of the more
common and user fixable problems are listed below for your information.
Please check the following list before calling your nearest BenQ Customer
Service Center, and attempt the following steps to diagnose and fix the
problem yourself:
Symptoms Possible causes
The display does not
turn ON
• Check that the power switch on the power outlet is
turned on.
• Check that the power plug is securely inserted into both
the
AC-INLET
socket on the display and the wall outlet,
and that the wall outlet is switched on (if switched).
• Check that power is available from the power outlet by
trying another known working appliance (e.g. desk
lamp) from that same power outlet.
There is no picture or
sound
• Check that the display is turned on (The power indicator
should be green).
• Try a different input source to confirm if the symptom is
still present or whether the source is at fault.
• Check for mis-connection of cables for that input.
• Adjust the volume control to check that isn't turned
down
.
• Make sure that the
Speaker Out
option in the
Audio
menu is not set to
Off
.
• If the display is connected to a PC, make sure that the PC
is not in standby or hibernation mode, and the PC’s
video display is switch to external output.
The cable connection
is correct, but there is
only sound and no
picture is displayed
• Check to make sure that the cables are firmly connected
to the terminals on the display.
• According to the type of input signal connected, refer to
"Supported PC (D-Sub/DVI) input signal resolutions" on
page 30 , "Supported Component Video input signal
resolutions" on page 30 or "Supported HDMI input
signal resolutions" on page 31 to ensure that the input
signal resolution from the signal source device (e.g., the
PC or TV game console) is supported by the display
(maximum 1080i for HDMI and Component Video
inputs, and 1360 × 768 @ 60Hz for PC and DVI inputs).
If the input signal resolution is too high or not
supported, the picture will not be displayed. Lower or
select a compatible signal resolution on the signal source
device and try again.
