Came home tonight to "Total Signal Loss" message on screen. My set up is DPP44 switch connected to dish pointed at 110, 119, 129, receivers are 722k, 622, 612. All show total signal loss. Power inserter for DPP44 switch is plugged in with light on. All other cables are as they were last time I did any maintenance a couple of weeks ago, new cable ends to get rid of any corrosion etc. Everything was working fine last night. In the past the switch has always been warm to the touch. But tonight it is as cold as the ambient air. Any easy way to test if the switch is dead? I could try hooking up one satellite feed directly to one receiver and see if I get signal. Any other simple checks for switch operation? I did run check switch which took quite awhile and then went back to Total Signal Loss.
