Backup camera flickering

[wickedwyrm]

I have a 2010 and the backup camera just started flickering a couple of days ago. The side view cameras aren't flickering, so I know it's not a problem with the NAV screen.
Does anyone know if this is covered by the CPO warranty? I know it specifically excludes "Radio/cassette player, telephone, navigation system, CD changer, or any components of those systems; non-original equipment parts, components or accessories." Was just wondering if you think the camera would be included or not.
I also seems to happen when it is hot outside, so I'm wondering if it is just a plug that doesn't have a good connection. But I don't know where to start looking for plugs to check.
