I moved my TV/Sky box last night which meant disconnecting all the cabling. On reconnecting the Sky cable and switching on I was greeted with a message stating that no satelite signal was being received I disconnected/reconnected the cable making absolutely sure that the thin wire had gone in correctly - stll no signal However sometime later I started to get a signal but it was very flaky - the signal test showed both the signal strength and quality indicators fluctuating wildly from zero to 50% - for a time I had a solid picture on some channels (esp channel 5) though most showed no signal or fault on channel messages This morning I'm back to no signal I find it hard to believe that moving the equipment coincided with the dish being affected by the high winds/rain we have been having so can only think that there must be something wrong with the Sky box. Has anyone experienced a similar problem and were able to fix the problem? What does the 'System Healthcheck' in the setup menus do? - it says "your incident number is xxxx" and asks for my pin number but then just beeps at me and changes the incident number after I enter it My Sky dish is 20' up on the front wall and I do not have a ladder - can the alignment be checked from inside the house by sticking a meter on to the end of the cable? Is there anything I can do to diagnose the problem- the box is about 2 years old and I assume Sky will charge me if they need to fix it?
