Hi; I have a Bell Expressvu Model 9200 Receiver Tuner No.2 stopped working on 82 degree sat. EVEN transponders missing only. If I measure the voltage on the coax terminals (with no connections to any switches lnbf's etc.)on the receiver rear...the voltage on the odd transponders is 13.6 vdc. but does change when I go to the even ones. If I switch to sat 91 on the screen the voltage switched between 13.6 odd and 20.0 volts even. Tuner No.1 functions normal on all transponders 82 and 91 deg. The sw-21 switch has open connection on the 82 deg Lnbf at the same time. Lightning here in January unusual-but we got it! Lightning storm damage maybe??? Any thoughts-anyone!
