My wife was watching tv last night, and the check switch screen came up. It started going through 1 of 38 checks and would just continue to do this. I did a soft reboot, a hard reboot, I left it unplugged over night and plugged it back in, same thing. I checked all cables and all are ok. On the dish side, I was only using 1 out put so I switched to the other output and no go. I get a 503 error - tells me switch box is bad. I then go and run a check switch and I get a 530 error - and it tells me that I cannont get the full service due to a problem. So, I am assuming I have a bad lnb/switch? I have a Dish Plus Pro lnb. Anything else I can do? Thanks in advance!
