NO IMAGE ON MAIN DISPLAY

states, “No Input, Check Cable”. If the cable from the computer to the display is
secure, determine the color of the standby LED and follow the appropriate
procedure below.

• Connect the power cable to the AC outlet. Ensure the
AC outlet is active.

the Configuration menu is the “Channel Select” option. Switch
between A and B to activate the proper channel.

not a black screen.
