New to DirectV and I was hooking up Direct dish using old RG6 cable used on Bell system. The power inserter for the SW44 switch was still plugged in and when I hooked it up to the SWM LNB there was a spark and the system would not work until I replaced he LNB. Could the SWM LNB be repaired or do you think that there could be something else wrong with it. Is there any way of testing the LNB? From what I have read so far the voltage for the SWM is 21 volts and the voltage for the SW44 is 20 volts so I'm not sure if it was a voltage issue, Any input would be greatly appreciated. Thanks
