Have this exact same problem, my open box V8S was working fine in my living room until I purchased a ZGEMMA box and stopped using it downstairs. I installed it upstairs in the bedroom and it worked great. I disconnected it whilst decorating and when re-connecting it recently the usual LOAD happens and ends up indicating a channel but no picture, nothing at all on screen in fact. having tried a load a few times with the same result i decided to try downstairs again. The same result but after laying for a while it started working again so disconnected and tried upstairs again , unfortunately the same result. Used all the same leads as downstairs and the satellite cable is using the same LNB and satellite dish as downstairs.
I thought it was the HDMI lead at first as the LOAD was taking place and channel number was indicated but no picture was showing on screen, but when I switched the box off the screen displayed "NO SIGNAL" which would indicate that a signal was being received from the box. I am now at a loss.
Any Ideas?

Finally resolved the problem - not sure what was wrong but decided to try the scart output instead of HDMI and low and behold it worked. Once everything checked out decided to re-try the HDMI and all works fine again - at first I thought it was probably a loose connection on the HDMI but have tried to recreate the problem by wiggling the lead without success so not sure what the problem was but all now OK.
