the device works flawlessly capturing videos and switching between all cams but just one thing odd is the white banding lines it produced

somebody suggested me that to use something like picture below to eliminate interference but still no cure

just right before i'm giving up, i noticed something when i pulled out the power cable from the device just leaving some portion of it slightly inside the device, the white bandings vanished miraclely all of a sudden

but this didn't last long once i reinserted the cable deeper to fully into the device, the white bandings reappeared again.......
what could be possibly wrong happened here? or any solutions that you guys can be suggested for me to solve it? thx
