I am at work so I don't have my equipment info handy. Off the top of my head, I have 3 receivers one 622, one 222 and an old black one that I think is like a 322(?). Don't know the switch or the dish set-up, except that I have two dishes and one of them says 500 on it.
When i say I "moved" I didn't ever actually move the equipment, I just changed my service address. The equipment that is installed at my house now was put in by dish about 2 years ago, has never been changed or moved, and has been working perfectly until yesterday morning.
I am going to try the unplugging the receivers for 30 minutes thing when I get home tonight. Anything else I should try before calling Dish?
