2 nights ago I noticed a 721 error on my main TV when I turned it on. Did a hard reset, unplugged Receiver, etc. Checked other receivers around house, and all HD boxes had same problem. Called Tech support, and got the usual response, which was what I had already done. They tried refreshing, but no change. Set up a service call for this coming Saturday. Last night I started playing around with different things: Swapping wires, moving boxes, etc. I refreshed from Website on all units, but no change. Then I went into settings menu on each box, and on Display Preferences, I switched to SD only, and all units started working. Unfortunately, now I can't go back, or have HD channels to show up on guide.
Any ideas? Would love to get HD back and cancel service call. I do have Protection plan, but I don't want some monkey ripping apart my entire set-up. I have 7 receivers, all over a multi-story house.
