I had dishnetwrok installed about 6 months ago and it hasn't worked correctly in my living room snce it was installed. I called for tech support and I was told that I would have to pay for them to come out since they took a picture of the signal before they left. The problem is that when I power on the receiver I get a blue screen showing that the signal has been lost on any satellite. I can go outside to where they installed the box with the barrel connectors and disconnect one side of the cable and after about 5 seconds I can reconnect the cable to acquire the satellite again with perfect signal on 119,129 and 110. I thought maybe it was a cable problem and if you try wiggling it you will not change a thing. it hought maybe it was the barrel connector, so I installed a new one. I still have to do the same thing and simply disconnect one side of the cable momentarily and reconnect to get full reception. I am truly baffled at this! Any help or ideas would be greatly appreciated. Thanks!
