I had problems with HDMI on a 211 after getting a software update. Dish sent new receiver with 268 on it and worked perfect. I disabled software updates. I woke up this morning turned on tv and receiver and found no picture only sound. channeled up and had picture. channeled back down picture for a second then blank only sound. I then got picture back after reboot. Went into menu to check software version and its 340 now. Checked my update setting and its still set to disable......WTF
