Only black and white image

Power on but no picture
Make sure the AV and VGA cable are secure from the video out connector & VGA signal
output connector. Make sure you are using the standard power adapter included with the
monitor.

or loose pins in the cable connector can cause a bad connection.

Check that the battery is installed properly. Also make sure the battery is not low. Make sure
the signal is not being blocked by obstructions.

Other problems
