Hi, I had trouble getting a proper installation job from sky due to strange layout of my flat so I decided to install cabling myself and bought Sky HD box from ebay. I know there is nothing wrong with my cabling since I can run my current sky SD box from both the inputs. But if I plug in my Sky HD box I get "no signal". The only way I can fix this is by going to the LNB setup (4-0-1-1 menu) and turning OFF the 22KHz and LNB Power. I then have to turn the Power back on but leave the 22KHz setting to OFF. This gives me the channel listings, BBC HD, ITV 1, ITV2, ITV 3.. But no other channels. All other channels are still "No Signal". If I switch the 22KHz back on and turn off-on the box then I get nothing again. 1)Is this a broken box or fault in my LNB? 2)Could this be because I havent called sky to assign my card to my box yet? (dont wanna do it befor I know it works) 3)Ebay guy said the box has 1 years manufacturers guarantee. (as all electronics in EU should have). Problem is, sky wont hear of it. They said boxes are only fixed at location of original install. I then tried to call thomson and cannot find any number to get through. they are a complicated company and no-one knows of any department that would deal with sky boxes. There are no official numbers either on the internet/telephone book etc. If anyone has any ideas of what I might do to fix the problem I'd love to hear from you. I have to add the LNB I am using does have another box connected to it. But as I mentioned, everything works fine when I connect my SKY SD box to it. HELP!!!
