Sortor82 Posted May 25, 2020 Report Share Posted May 25, 2020 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? Quote Link to post Share on other sites
joepro63 Posted May 31, 2020 Report Share Posted May 31, 2020 I know that if you do a firmware update with the same firmware it will still do it.. if youre getting an error then something is going on. Quote Link to post Share on other sites
SpecialtyGreg Posted June 4, 2020 Report Share Posted June 4, 2020 PAC audio makes a rca filter called RPA-VA1, this may help https://catalog.pac-audio.com/catalog/backup-camera-retention-harnesses/rpa-va1 If your'e using more than one video into the same circuit, you may need a video amplifier as well as a video switcher Quote Link to post Share on other sites
