A green tinted image sounds like a colour is missing or lower in value than it should be or perhaps the green signal is permanently high, i.e. red, blue and green colour signals are used to make up all the colours depending on their value, e.g. 100% red + 100% blue + 100% green = white. Here’s a RGB colour chart that explains it better than I can Note: 255 value = 100%. Hover your mouse over the various green colours in the green colour section of the colour grid chart and check the values below to see how the colour is made up.
It could be the camera not sending either the correct blue or red signal or green is set permanently high, so green predominates or perhaps even the monitor not translating it properly to be sent on to the display. The monitor is OK internally from a section of the motherboard to the display as the menus etc are OK but this is a different part of the circuit to the signal reception circuit.
One way to prove whether the problem is with the camera or the monitor unit is to connect another DXR-8 compatible camera to the monitor and check what its display is like. According to p.13 of the user manual 4 cameras can be connected at once.
Perhaps you know someone who also has the monitor system and will loan you the camera so that you can test your system. It’s probably the quickest way to find out where the problem lies as there are no schematics available online. (None that I could find anyway)
