Hello, I have a w8400nex. Recently my video for backup camera is rainbow scrambled, and jumping around. Things I tried:different cameras, hooked a DVD player up and same thing happens to both camera input and video input. It’s not the rca cable, tried different ones and verified it works in the house. Tried resetting settings. Tried button reset with pin into the face. Tried to do a firmware update, but it says error, possibly cuz it is already up to date. Tried video setting of pal, ntsc, auto, etc.
So I have three cameras ran through a video switcher. I have eliminated the switcher while trying to troubleshoot this issue, so it’s not the switcher. The weird thing is one camera works fine(It’s a boyo camera), while any other camera or video source gets scrambled. Maybe the signal is a different voltage, not sure why it works and nothing else.
Anybody have any ideas?
