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 adapter.
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.
Control buttons do not work
Press only one button at a time.
