I have been racking my brain at this one for a while. I have a dish 1000, vip 622, 501, and FTA receivers. I ran rg6 out of 1 of the 2 slots on the 129 lnb, and 2 rg6 runs out the 110/119 lnb (they are ran out of the 2 left slots and the right slot is empty.) I have ran all 3 cables to a dp34 switch. At times my FTA is picking up all 3 sats and working fine, but some times one of more sats lose signal and it doesn't work at all. When I run a check switch on my 622 and 501 it shows a reception error but when i go back to the signal meter on 110, 119, and 129 they all show good receptions. I have changed coax out and still the same problem. I have tried running coax directly to the receiver (bypassing the seperator) and still no luck. If I hook up the the lnb's with a cable connecting the 129 to the 119 and bypass the switch everything seems to work fine, although I only can run 2 recievers (which is the way the installer hooked it up). Do you think my switch is bad? I am running my cable wrong from the lnb's? I cannot think of what else I might be doing wrong. Please HELP!!!
