Navman M100 Display Blanks after power-up.

[ChunkyMonkey]

Can someone help me out here? I have moved my Navman M100 display. On power-up it blinks and then goes blank. The polarity is not reversed. Any other possible causes of this? /forums/images/graemlins/confused.gif

it may be the voltage is dropping because of bad connection somewhere. Put a mulimeter on the power connector and turn on, watch the voltage when it comes on and see if it drops below 12v
