Sony BRC-H700 PTZ Crushed Blacks

I purchased a secondhand BRC-H700 PTZ camera and have found it has crushed black levels.
I have checked all the menus, read the manual and done google searches but I can't find any master black or black color correction. I can't even find an auto black balance.

Is anyone who has this camera able to help me find the adjustment or confirm there is no adjustment available.

Setup is 1x BRC-H700 camera, 1x RM-BR300 remote control unit and 1x BRU-H700 Optical Multiplex Unit

This is very common on Sony PTZ sensors.. We did a shootout a while ago between Lumens and Sony.. And found out it has lots more noise in the black.. And also crushes the black.. Were the lumens still give details and much less noise..

Do you also see ghosting in the black when you move left right?? At least we did see it on the SRG-300
