SAMSUNG UE65HU8500 ONE CONNECT pinout connector request

[AlexVG]

Hi,
I came across with
SAMSUNG UE65HU8500
ONE CONNECT BN41-02135
Chassis GOLF_UHD_1MP_JACK

TV can not recognise ONE CONNECT box, so I need to know the pinout of the CN 3301 connector.
Moreover, on the main is written A5V. However, cable connected this pin to the GND.






Maybe somebody have an experience with the same issues?
I need your help.
Thank you.

A common problem is in the cable itself.

Thank you,
I opened it, but without of pinout or scheme, I can't check it.
