DTH satellite receiver problem Answered

I have a DTH satellite receiver which has a burnt SMPS power supply (image attached). I replaced the burnt components but again when powered with 220V ac supply to test the output voltages the same components burnt again within a few seconds. I could not figure out what is the actual faulty part. If anyone has any suggestion please feel free to answer. My second problem is the satellite receiver board (image attached) has 6 pins for power connection but I could not figure out what voltage is to be applied to which pin. So I was unable to use a separate power supply for the receiver board. The part number can be seen from the image itself. Please look at the receiver board and help me if anyone has any idea about this board. I tried searching in google with the part number but could not find the same board. Please help me. Any suggestion is welcome.
Satellite receiver: Hicway ali M3328C(10039)-11
