When you run through the setup wizard which output devices do you see in the available list, hdmi, rca or ?????.
Also you say other images - which??
Also just to exclude a possibility, maybe you could turn on debug logs (menu/setup/system//logs/settings) enable debug and change log location to HDD or USB (not flash)
Then exit twice and hit factory reset
Go through the wizard, let it reboot and then post the debug logs.
