    Hey all ... My dish was relocated today and stupid me didn't check signal strengths on any receiver connected to the SWM8, and I just found out all even tronsponders are 0 on the SWM DVRs.

    I have another HR20 on the WB68 that is getting both odd and even transponders, so it's only an issue with the SWM8.

    Ideas what to do? How to troubleshoot and resolve?

    I unplugged the SWM8 PI for 15 seconds but that didn't do it. I saw from one search it should be for 2 minutes, so I'm going to try that next.

    Should all SWM DVRs be unplugged before I do this?

    Any help is appreciated ... If I can resolve this tonight I will be very happy.

    I would unplug power from all of the SWM receivers and replug them one at a time. I recall reading that you should wait until Step 1 of 2 before powering subsquent receivers.

    Unplug all DVRs, unplug SWM. Wait 2 minutes. Plug SWM. Plug DVRs one by one.

    Drew, is this ALL evens on 101, 99, 103, and 119?

    Or just a subset. I'm thinking a bad cable from splitter to SWM.

    Or even just a connector...

    Tom - It was all evens on all sats (101, 103, 110, 119, 99).

    The receiver on the WB68 is seeing both odd and even on all sats, so it's just the SWM8 connected receivers not seeing the even transponders.

    I didn't touch any of the inside wiring and it was working great before, but I suppose there could have been a surge when the dish was reconnected outside and one of the inside cables got zapped from a splitter to the SWM8?

    Right now I've unplugged all receivers and the PI for the SWM8 and will let that sit for 2 minutes, then power up the SWM8, wait a bit, then power up one DVR and see what happens ...

    Good idea....

    But if that doesn't work, I'd still check the connectors as with age, I've seen them "go bad". With the reinstall of the dish...I'd start there and work my way back to the switches.

    I'll go through everything to play it safe. I also just dug out my SWM5 and I can swap that in for the SWM8 to rule out cables versus the SWM8 itself failing.

    The only connections changed or touched today were the ones on the dish itself. I relocated my dish from the roof to the side of the house (due to an upcoming new roof being put on) so the dish dropped down about 12 feet and the four runs of RG6 from inside to the dish were cut accordingly and new connectors put on.

    OK, it's been more than 2 minutes, so I'm off to restart the SWM8 and one receiver ...

    Keep us posted buddy...the SWM5 swap would help further narrow the source if the SWM8 and then receiver attempt doesn't come up....

    No good after the 3+ minute cool-down with the SWM8 so I'll pop the SWM5 in to see if there is any change.

    In a way I'm hoping that doesn't work, so that the SWM8 is eliminated as the potential source of the problem...again...maybe a connector or something else...

    :D You just really want it to be a connector, don't ya?! :p

    Let's see ... three connectors per splitter so 12 total, + 6 on the WB68, + 2 on the PI ... that's a lot of connectors to check! :nono:

    So right now I have the SWM5 in place of the SWM8 and I'm restarting the HR20.

    By the way, when I power-cycled the SWM8 and restarted this HR20 the last time, it saw no channel below channel 70.

    I'm hoping for better results with the SWM5, because at least that would work to send signals to my upstairs receivers and I have enough free ports on the WB68 to make my living room receivers work.

    Well - it took awhile, but I finally am back up and running! Thanks for the assist folks!

    Short story: It turned out to be the splitters ... there must have been a surge, because all of them got fried somehow. I had to replace all four splitters, but I'm just happy the surge didn't damage the WB68 and SWM8 ... and the DVRs!

    Glad to hear you are back in business. Often, these problems are the little things, like connectors or splitters. Good that this was the case, and not something more serious like the SWM8.

    Welcome back to the HD world!

    Choctaw, OK
    So what's inside a SWM-compatible splitter that is fry-able?
    I've never had one apart.

    possibly the isolation diodes that limit power passing and cross power feeds.

    Good point :) (Tho some components are more likely than others. The case itself takes a bigger current to fry than say the wires...) :D

    I can tell you one lesson that was hard-learned today: Power off all receivers and unplug the SWM PI before playing with the sat connections ... or cutting the sat lines outside.

    Not gonna do that again ... nah ah, no way. :nono:
