The HR34 does have a power saving option, and I just turned it off. Rebooted the C31 (can't adjust power saving from the C31), still won't turn on using any of the power buttons on the remote or the box.
I tired that as well, it was suggested on Direct TV technical forums, didn't fix the issue (that was before the resolution issues). Btw, I put a watt meter on the clients, when turned on they draw about 6 watts and when off about 4 watts.
My wiring is very simple. New RG6 from dish to 8 way splitter inside the house, from the splitter RG6 to H34 and each client(no additional spliters). All wall connectors replaced to support 3 GHZ signal. For a network connection I have Cat 6 running from LAN port on H34 to my router (same line was used for VIP722 and never had any issues). I tested everything with CAT 6 connected and disconnected, each time resetting everything (all this done before reloading firmware and resolution issues).
My installer said that he did 4 similar installs since he did mine and didn't have a single issue. Hopefully replacing the H34 tonight will resolve it all.
