Zinwell WB616 Discontinued

Yes, it's discontinued.  You might find one on ebay.

If all your receivers are SWM-compatible (all the HR20s are) , replace it with an SWM16 multiswitch/power inserter, then you only need one cable from the multiswitch to each DVR.   If they are not, you will need two WB68 switches driven in parallel by splitting each of the four lines from the dish, using broadband splitters, power-passing on both ports.

Are you sure the multiswitch is faulty?  What testing have you done? Do you get any signals on 103ca on any of the DVRs?  It would be very unusual for the multiswitch to lose all of 103, because the 103 odd and even transponder signals are carried on different cables to the multiswitch.

I have a Hr20, 2 HR21 and 2 HR22 hooked up to this system. TO test I connected one of the recievers directly to one of the 4 feeds coming from the dish. The 103 sat signals where then present on the receiver where before they where not. None of the five receivers are getting a signal from 103 after the multiswitch. I also had to switch one of the recivers to a different port because it was not reciving any signal at all on the one port. It is now fine with the exception of 103

Well if you have lost all the 103 signals on all the ports  it certainly looks like a multiswitch issue.  Is the power module connected to the multiswitch and working? What signal levels do you see on 103ca when you take the multiswitch out of the circuit (post all the transponders).

You might try moving the 4 inputs on the multiswitch to different ports.  If the lacking signal becomes something different you'd know that cable from the switch to the dish is faulty.

As an aside, you only listed 4 DVR's.  If that be the case, then that's only eight tuners and you can use a Zinwell WB68, don't need the 16.

No, he listed five DVRs.....ten tuners in total.

If it's a cable you should see half the 103ca transponders (either odds or evens).

I am going to replace the multiswitch with a SWM-16 . that should solve my problem and also upgrade the system for interconnectivity. Thanks for the help !!!

Yup, I miscounted for sure.

keep in mind that not all receivers are SWM compatible.  what model of receivers do you have?

and the SWM16 is like two SWM8's.  you need to balance the tuner count on each output to no more than 8 tuners

I installed the swm16 switch. all the receivers are working. I am getting all the channels now. But I am getting a error message on satellite setup. "there are errors in both tuners. Check your installation" there is a schedule below it with the 99 sat having X's in the odd and even catagory then the rest of the sats have checkmarks. any idea if there is something wrong or is this just a glitch in the software. everything seems to being working ok on all receivers.

what the error means is that your satellite signals are not up to DTV's specs.  if an installer was activating your receiver, he/she will be forced to re-peak your dish before they can proceed with activation.  please post your signals readings  on the affected satellite.

Yeah, those readings are too low.  The 99º(c) readings should be 10-20 points higher.  Your dish alignment is probably off a bit.
