OK Guys, hopefully someone has had this issue or can help. I am out of ideas and pulling my hair out. First I must say I changed nothing in my setup except my C band dish. I am using all the same wiring and LNB's. My setup consists of a 7.5' C-band mesh with a single output PLL LNBF and a V box to move it. I also have a Primestar 84e with the dual output Eagle Aspen LNBF and a USALS mover. This is all going to my X2 Premium HD FTA Receiver. My setup has always worked GREAT! I use a 1X4 DISEqC switch with c band on 1 and KU band on 2. The problem I am having is when I set everything up on the receiver and blindscan I receive C band channels on both c band and KU band and never scan any KU channels. When scanning it shows KU Frequencies but picks up C channels. I unhooked the DISEqC switch and went straight to the KU dish, Scanned all KU Frequencies fine. Hooked directly to the c band dish and scanned all the C frequencies fine. I replaced the DISEqC switch and same issue. I had all the KU Frequencies scanned in the first time and I received KU frequencies but when I changed channels my receiver kept restarting itself and defaulting to the original channel. I deleted the Transponders from history and it stopped restarting. I feel this HAS to be a problem with the KU dish but everything works when the DISEqC switch is removed even the motor... PLEASE HELP I'm out of ideas!
