After updating the system last night I had to do a full system reset. Sound worked but not display (for stuff that was working previously -- pretty unbelievable). Even setup had stopped displaying anything! I think that maybe they've fixed it, but I was so mad that I wasted 45 minutes restarting things and resetting things to try and get it sorted. Here are the reset instructions for the Bose that I was sent when debugging the other issues... A reset is used to correct occasional product issues. It is not something that a product should require repeatedly. Perform a system reset by following these steps: Keep the TV and control console on On the control console, press and hold Source and Power for five seconds. The TV and the console will turn off. Release the buttons. The white LED on the console should turn off; If it didn't, perform the step above again. An amber LED will blink once. After this occurs press Power to turn on the system. The LED will flash amber then white while the system turns on and reboots. Wait 10 seconds after the LED stays solid white before retesting the system.
