Side Cameras Not Working

Both the left & right side view cameras are not working. The monitor switches with the turn signal but the screen is grayed out, guidance lines display and can be turned off. The backup camera displays properly. Have power to mirrors for adjustments & heat but apparently no power to the cameras? Looked for separate fuse for cameras with no success. Called Winnebago Customer Service, they have no record of separate power for side cameras. Checked settings on radio/receiver only setting is for rear camera "Off, Normal & Reverse" but the monitor changes to the side view.

Velvac Mirrors with integrated cameras, Sony Radio receiver with 1 coax input behind radio.

I'm stumped, anyone have this problem?

Just picked up MH from Freightliner for LOF, and Trans cooler replacement. ECM update & filter changes.


Found Radio manual online. Radio has 1 input for backup camera which leads me to believe there must be a control box add on. The control box must control switching the camera to the single input of the radio. That operation is functioning so, the control box must have power. Now the question is: does the control box also power the cameras thru the coax? I've sent a query to Velvac.

Looked at the Winnebago drawings online, they all show the JVC radio with 3 camera leads.

Is anyone familiar with the "control box". Figure it must be behind the dash somewhere.

UPDATE part 2

Researched:, Velvac, Sony and Winnebago Customer Service. The side cameras are definitely powered by a switcher.

Ron from Winnebago provided assistance in removing the Bezel and I found a Voyager CSW3 Switcher. After checking each camera with the one working input, put it all back together and was surprised that everything works.

Anyone finding a VOYAGER CSW# Switcher Please let me know, Thanks
