Why in total darkness does the unit just flicker with no picture? with infrared it works fine

Nearly all cameras work well in the day. Night vision depends on the type of camera and the technology it is using. For example a CMOS based camera will provide a very poor quality picture in the dark. A CCD Super HAD CCD II will provide a good picture with 0.01 illumination and a EXVie HAD CCD II will provide an even better picture with lux of 0.001. You really need to look at the specifications of the camera before you buy and not go with the "Platinum" or hype keywords used by the manufacturer. I have seen a lot of SWAN Cameras which are basically useless at night.

Sounds like the infrared light is not working, need to check with Truth cam Primos about that.

Your back light inverter is provably bad.

You can get get parts for this tv at www.interliquidparts.com

It will only see anything if there is an infrared light source. It's got an infrared led for this, but that wil probably only illuminate the first meter from the camera, you need an IR light, such as the onse used witrh security camera's to see further

Reset satellite data and the flickering went away.

it could be as simple as the tv feeding back on itself in a dark room.
it is adjusting the light level because of what it sees ambient in the room.
turn on a light near the tv and see if it stays constant now.
