Troubleshooting

No power

•  Make sure power button (or switch) is ON.
•  Make sure A/C power cord is securely 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.

Power is ON but no screen image

•  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 adap

Wrong or abnormal colors

•  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.
•  If you have an older graphics card, contact ViewSonic

®

 for a non-DDC adapter. 

Control buttons do not work

•  Press only one button at a time.
