the second won't pick up the dish signal on channel 21 or 73 the picture won't come clear I tried adjusting the satelite and transponders nothing changed help me please!
You need to set the channel number for the second TV using the menus. This is explained in the dish manual on hooking up the second TV. Tyhe second tuner is generally on a different TV channel. That way the second TV can receive outputs from both tuners. I forget what the defaults are.
