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 assistance.

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

Power does not turn ON.

• 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.

• Check that power is available from the wall outlet by trying

another appliance or desk lamp from that same wall outlet.

There is no picture or sound.

• Ensure the TV power is ON (indicated by the green Power

indicator on the front of the TV)

• Try a different input source to check whether the source is

at fault.

• Check for mis-connection of cables or for wrong input

source.

• Make sure the antenna cable is properly connected.

• Change programs to confirm if the symptom is still

present.

There are spots on the screen.

Your TV antenna signal is being affected by interference from

automobiles, trains, high-voltage transmission lines, neon

signs or another sources of interference. Try redirecting or

relocating your antenna to reduce the affects of the

interference. If the antenna is exterior, have a suitable

qualified and experienced antenna specialist adjust the

antenna.
