hi
i have openbox S9 which works OK for H polarization but there is no V
i chacked voltage from tuner to LNB and during H (24V) to V (should be 14v) switch there is still 24,5V.
it's mean some kind of 5legs switch is damage but i don;t know which one.
there was same problem with dream dm500 so openbox should have same 5legs switching chip who operates H to V polarization switch.
i checked your picture with FIX (diode) but this will not help me.
please advice me which one 5legs chip operate for H to V polarization switch
thanks
