Troubleshooting Peak Wireless Backup Camera Monitor LED Blinks but No Picture on Monitor

Expert Reply:

I spoke with my contact at Peak, and when the blue LED is blinking, and you do not have a picture, it means that the monitor has power but it is not receiving a signal from the transmitter. This can happen for several reasons so you can check a few things to narrow down and pin point the problem.

I am assuming the unit is wired according to the instructions. If so, it will only come on when the truck is in reverse. If the truck is on and in reverse and the LED is still blinking and you have no picture, then you need to look at the transmitter.

The transmitter needs to have a fairly clear transmission path to the monitor. The closer the transmitter is to the monitor, the better. One of our installers has this unit on his SUV and he had to mount it inside the rear cargo area underneath one of the plastic panels. You may even need to extend the wires between the camera and transmitter using Extension Cord for Wireless Backup Camera System, # PKCORD, since you have a full size truck.

If you move the transmitter around and still get no signal, it could be that the camera or transmitter are not getting power. Check your wiring and make sure that the vehicle wire you have the transmitter connected to supplies 12V when the truck is put into reverse. I have included a link to a video review and install below for reference.
