Hi,

I have problem with my 7020S. The motor will not move when I have chosen a TV channel with vertical polarization. I have compared the DC-voltages for selecting the Horizontal and Vertical polarization for the LNB (that also drives the motor) with my other working sat receiver and found out that the 7020S has a lower voltage on the vertical (13.0V compared to 14.0V) and ok for the horizontal (18.0V compared with 18.1V). As I understand the standard says 14.0V and 18.0V so the center should be at 16V +- 2V. Is it possible to make the vertical voltage a little higher with a sw patch or shall I try to change the power supply?
Does anyone have documentation on the power supply?

I am running Gemini 4.5.

Answers in Swedish or English please if possible.
Thanks in advance
