How to fix no video on L3 Mobile-Vision Monitor?
- DDoris DiazAug 5, 2025
If there is no video on your L3 Mobile-Vision Monitor, first ensure the Mobile Vu Display power button is on. The LED on the front should be lit. If that's not the issue, toggle the Input Select button on the rear of the display. Also, check the brightness control and increase it if it's too low. Ensure the MV-1 is powered up, and check the input power connector for 12 volts, as well as the fuse. Finally, inspect the MV-1 wiring harness and connectors for any damage, ensuring the VGA connector is properly seated and the cabling isn't damaged.
