I have dishnetwork with dual receiver 522. Initially it was setup for use with two TVs. However I was using it only on single TV in single mode. Now I got a Second TV, so I switched back to dual mode. But some how I could not able to get the signal to the second TV. I verified the channel, and it is showing as 60. I tried up to channel 69 but no signal is coming. I am at a loss to understand what the problem is. Any suggestions appreciated.
