Eurovox no signal

[pigs feet]

Hi Guys and Gals.
Since last tuesday my urovox max v started getting a poor signal on most channels and no signal on the rest ( BBC1,2 channel 3 and 4, sky sports and many more). I have 2 boxes up an down stairs and they are both the same. The connection come direct from the vm box outside ( which has 2 seperate feeds for the eurovoxes and 1 fr the broadband)and direct to the eurovox's and internet. I have re scanned, power scanned, and reinstalled factory settings but still no joy. I have brought a signal booster, which increass the signal from 80 to 85% but the signal still keeps dropping down to nil every couple of seconds. I cant see a problem with cables as nothing has been touched. I have tried box at different address ad works fine. The VM box also works fine at my address. I have also downloaded the 8% fix last night but still the same.
Not sure what else to try. Does ayone have any ideas. Will th latest filmware Eurovox Max+V Kuro v3 Final 18042008 make any difference to te signal problem.

Thanks
