It doesn't really matter which transponders they are on (they can and so change). You should have approximately the same signal strength (80s at least) on all the available 103(c) transponders. If you don't, you have a problem (probably dish alignment).rb5505 said:is there a list of which channels are on which transponders for 103c? i thought i'd seen a link where some guys are working on that.
thanks for the helpful replies and links.
Not a dish alignment issue. Looks like a multiswitch and/or LNB failure.rb5505 said:here are the transponder readings. those not listed show a "-".

the 110-12 tp is always 0.K4SMX said:Your 103(c) evens are missing. They are controlled by the 18V + 22khz tone signal voltage to the LNB, which also controls the 119 and 110 evens, which you have not lost. (I think that zero on 110 tp 12 is probably a fluke and recommend you re-test it.)
Since you have DVR's, and they are both doing the same thing, presumably on both tuners, attention naturally falls on the LNB or any external multi-switch you may have, as Radio Enginerd says. If you have any additional receivers, you also have an external multi-switch which could be malfunctioning. If so, you can test it by bypassing it with "barrel" adapters, using the two DVR's only.
Sometimes this condition is caused by loose or corroded connectors. So I would grab a 7/16" wrench and remove and inspect for corrosion the connector on the dish side of the multi-switch marked "18V + 22khz." Re-tighten until just snug. There is also the possibility of corrosion on the other end of that line, which would mean you would need to remove and inspect all the connectors at your LNB, if you have safe access to your dish. If you can successfully determine which line at the dish matches the 18V/22khz from the multi-switch, you'd only have to check that one line. Unlikely. Be especially careful not to over-tighten the connectors at the LNB.
Otherwise, you'll be needing a service call to swap the LNB itself.
I agree with Stew 100%. Great troubleshooting suggestion.rb5505 said:we have the usual zinwell multi-switch (8 wires coming out). i'll try the straight run next.
yes. i disconnected 2 of the 4 cables before the wb68 and connected them to the dvr. did the screenshots of the transponders. then did the same for the other 2. each time, 2 cables went directly into the dvr directly from the dish. the screenshots i posted represent one of the pairs.harsh said:I would guess that you need to disconnect everything from the WB68 and connect only the receiver in question. Did you do this?
I think what Harsh means is disconnect the 2 remaining cables fromthe WB68 and run the signal test again. 103c looks MUCH better.rb5505 said:yes. i disconnected 2 of the 4 cables before the wb68 and connected them to the dvr. did the screenshots of the transponders. then did the same for the other 2. each time, 2 cables went directly into the dvr directly from the dish. the screenshots i posted represent one of the pairs.
yes, 103c got much better, but what happened to 119?Radio Enginerd said:I think what Harsh means is disconnect the 2 remaining cables fromthe WB68 and run the signal test again. 103c looks MUCH better.
2 cables from the dish should be connected to the receiver while the other 2 cables should be connected to NOTHING.
