If the power LED is not lit, push the power switch to

turn the display unit ON. If the display unit is powered

through the computer, check that the computer is

switched on.

The display unit might be in standby state. Push one of

the keyboard keys. Check that the keyboard is properly

connected to the computer.

Maximize the brightness and contrast of the screen (see

section Adjusting the picture).

Check that the power cable is correctly connected to the

display unit and to the power outlet. Use a desk lamp,

for example, to check that current is connected to a

power outlet.

Switch off the display unit and the computer. Unplug the

display unit from the power outlet for about one minute.

Restart.

Check that the signal cable connectors are properly

connected and that the connection pins are not bent or

damaged. If the connectors are loose, tighten the

connectors’screws.
