Hi Wondering if someone can help, or if anyone has experienced a similar issue. I have Sky HD and two Sky+ multi-room boxes. One of my multir00m boxes on Sunday kept giving me the "No Sat signal is being received", when I checked the signal strength and lock indicator it was telling me that signal 2 lock was ok, but there was no lock on signal 1. I tried re-setting the LNB, but still no joy. So then I brought my other Sky+ box in and plugged the sat feeds into this, and got the same result (it was working perfectly in other room - also Sky HD box has been working perfectly). Then I thought, that just so we could watch TV I'd swap the RF cables between input 1 and 2 - when I did this I lost sat feed on both signal 1 & 2. I then went to swap them back and when I removed the RF cable going into 2 I got perfect signal strength etc on signal 1!? This is happening on both the Sky+ boxes - I can get great signal strength through signal 1, so long as I leave the other cable not connected - if I start to connect it to the box I loose the signal again - so it is currently dangling unconnected at the back of the box. The RF plugs both look fine and I cant see and damage to the cable, although havent been able to get to the LNB due to the slope of our roof. Sky tech help werent much help either - has anyone any suggestions? Thanks C. PS weather was fine at the time.
