Troubleshooting
There are many external influences and circumstances beyond the control of
BenQ which may be causing problems with your TV. 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

Ensure the TV power is ON (as shown by the green
Power indicator on the front of the TV). If so, check
that the remote control is working or not. Press the
Power/standby button on it.
If not:
• Check that the power plug is securely inserted into
both the
AC-INLET socket on the TV 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.
