When I put the TV itself on an input that has no live feed/incoming signal (AV1, AV2, Component, etc.) and is just showing a flat black screen, I get small variants of subtle contrast flashing. Maybe I shouldnt say flashing...more like subtle changes from a deep black to a lighter black.

What is causing this? It doesnt happen all the time, just once in awhile.
