I can't figure out what is wrong with my system. I have a Dish 500 and a Dish 300 both connected to a DP34 Switch. I have a 510 connected to the #1 to the receiver. No other receivers are connected at this point. The receiver shows 0 signal strength. When I have gotten it to work, it would only work with one receiver connected at a time. Now not even the one receiver is working. Is the switch going bad??
