[QUOTE="Crisbe, post: 635983, member: 327196"] Both cables take power to the LNB. If you have a dual output LNB you have to think of it as two seperate LNBs in one unit sharing the same feedhorn. Are you sure your dish is okay, if it is on a wall of your house it is not unheard of for a dish to get knocked by someone being careless with a ladder (for example a window cleaner) or by children hitting it with a ball. The dish would only need to be a tiny bit out of alignment to reduce the signal quality enough that you would get picture break up. Check the signal quality using the signal test in the digibox menu. If you have a lot of signal strength but the quality is way down this could be the problem. If you think this is unlikely to have happened and you have a friend/relative/neighbour (who has a working sky+ system) who will let you try your box in place of theirs you will see if it is your box which has the problem. Or if you can't do this you could buy a secondhand digibox for about £10 on fleabay and connect that to your downleads and prove if your dish is okay. Or alternatively, if someone will lend you a digibox for an hour you could try it on your downleads and see if it works on your dish. If it doesn't you know where your problem is. [/QUOTE]
