hi, my sky+ box (amstrad) has started to turn itself off,it goes into standby. strength on input 1 very low approx10% but the quality is approx 50%then it takes approx 3 mins to turn it back on. on input 2 the signal strength and quality are both approx 50% i have moved the lnb and dish and they did improve except input 1 signal strength. i also swapped the lnb inputs on the box this made everything approx 50% ut after 30 mins has gone back to how it was . any ideas
