No dishnetwork signal

OK here we go .the most common problem with dish network and directv is that any cable connections you have that are on the outside of the house are a HUGE weak point in the system.what you want to do is go outside and locate the dish once you have start following the cables until you find any of these cable connections or splices.once you have located them get a 7/16 wrench and remove the cable ..What your are looking for is corrosion in the cable connection.it will look like rust.What happens is your dish system sends 13 and 18 volts down the line to switch channels.When any water gets in these connections it will start to short the connection BUT,you will still get TV for a long while eventually this small short will start to damage the cable connection and you will lose signal all together.make sure to check all of these OUTSIDE connections.Once you find one that is bad you can go to radioshack and buy a cable prep tool that STRIPS the coax"COAX STRIPPERS" to its correct lengths.simply cut off the old connector and replace it.There is a GREAT tutorial at satellitescoop.com that shows you how to do this the right way for under 10 dollars make sure to follow the directions on that site and you should be watching TV in no time.
