Initial setup went fine. I went to the HD format menu item. It was set to 480i. I selected 720P and realized my mistake a second too late: This TV does not support 720P and goes black.
I ran into this with our old 622 and you could muddle thru the menu using the remote number keys. After a call with Dish Tech support, they had no solution other than to send a tech out out to the house.
I've run a composite cable to the TV on receiver output TV1. I can kinda get a picture, but selecting menu just gives the TV picture in the upper left and a big blank grey spot where everything else should be. I've switched the mode to Dual via the receiver keys. I can get the menu to display there, but no HD mode item.
Anyone have a diagram of the menu I go blind (like Menu, 2 clicks down, 3 clicks right, select, 1 click left), or any other suggestions?
