Troubleshooting
No power
• Make sure DC power button is ON(Green LED).

Power is ON but no screen image
• Make sure the video cable supplied with the Display is tightly secured to the video output port
on the back of the LCD TV. If the other end of the video cable is not attached permanently to the
Display, tightly secure it to the LCD TV.
• Adjust brightness and contrast.
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.

• Make sure the sound is not set to mute.
