My sons & daughters tvs are have been stuck on acquiring signal 535 all day. My other 2 tvs are working just fine. I have tried to soft reset it, did not work. Unplugged whole system and left down for a few hours and tried again, did not work. I checked "check switch" test and it said I have less satellites then orginially detected, but did not give me the red x? Still nothing works. I would rather not have to pay for a tech to come fix this if it possible for me to fix it? Please help & Thank you!
