• Make sure power button (or switch) is ON. 

• Make sure A/C power cord is securely connected to the DC power supply  

and the power supply is firmly connected to the LCD display.

• Plug another electrical device (like a radio) into the power outlet to verify 

that the outlet is supplying proper voltage.

• Make sure the video cable supplied with the LCD display is tightly secured to

the video output port on the back of the computer. If the other end of the 
video cable is not attached permanently to the LCD display, tightly secure it to
the LCD display.

• Adjust brightness and contrast.

• If you are using an Macintosh older than G3, you need a Macintosh adapter.

• If any colors (red, green, or blue) are missing, check the video cable to make 

sure it is securely connected. Loose or broken pins in the cable connector 
could cause an improper connection.

• Connect the LCD display to another computer.
