I've got a Dish system (Dish 500, 2 dishes, 1 522, and 1 301(?)) that crashed yesterday (1 hour before the Derby!). Ran a switch test and it says that under Sat Input 1 I'm missing port 1a odd, port 1b even, and port 2b Sat 110 even, and under Sat input 2 I'm missing port 1b sat 119 even. ran a signal strength before the switch test and got a strength of 100 on 119 on odd transponders 13-19, but nbothing on the even transponders, and nothing on 110. What's the problem? and are there places to look for tech info on these things?
