Hi all , have not long purchased a 20foot full sized expanda 2017 , and I can’t get a tv channel at all , the thing is the 12v tv socket at the door has decided to stop working as well , checked power output at the j35 under the lounge and it was only putting out 4v , had a spare slot that was putting out 12v so tried that one and Huston we have power once again to the Telly , (still no reception) . Work ok for three movies , moved camps 800km up the road and now it don’t work , had a red light come on the j35 which indicated a overloaded outlet , removed the one for the Telly and all went normal again . Any ideas , would be helpful cheers .
