Well, it was a good run. ~16 years of several DIY upgrades, and one move, with no issues, and now I've got some troubleshooting to do. Currently have a Hopper w/Sling/Super Joey on a DPP44/Solo Node/Integrator to a Dish 1000+ (the "old" version with the clear window on the 118/119 LNB, without the built-in switch). Purchased a Hopper3/4k Joey/DPH42/Solo Hub to upgrade. Swapped the switches, traded node for hub, connected the new Hopper, and it never completes the Check Switch. Doesn't see the switch, and sometimes after a reset it will see a "DP Feed" instead of the expected DPH42 and whatever LNB is connected to Port 1 on the switch, but no signal. I had accidentally reversed the "To Host" and "To ODU" lines on the hub at first, but after correcting that I don't think it killed the hub or switch. After numerous resets, and trying connecting directly through the switch instead of through the hub, I reconnected the HWS, and after a check switch it fired right up, sees the DPH42, all 3 tuners are fine, and after reconnecting the Integrator the Super Joey works fine. Considerations: The Hopper3 is a refurb, and a fairly scratched-up one, with SW version U501. Taking a multimeter to the Power Inserter shows it's only putting out 21V instead of 28V as indicated on the block (which has a DPH logo, so it is the correct one). So, bad Hopper? Bad Power Inserter making the DPH42 act weird? The switch doesn't like the LNBs? Anything else I should try?
