One of my customers has a Hitachi TV from the tiny slice of time during the development of HD products where some TVs could display 480i, 480p, and 720p, but no 1080 at all.
This was an issue when the DVD Player died and we replaced it with a BD Player.
The default output of the BD Player was 1080P so nothing showed on the TV. The catch-22 was that without seeing the display, the BD could not be switched to 720P. I had seen this problem coming so I dragged out my trusty $115 Best Buy 15" TV that could display everything (though not pixel per pixel). I set up the BD to 720P and all was well.
I had one like that recently, and somehow the cable box reverted from 1080i to 1080P, and the picture went blank. The only thing that saved me was that the voice assist was switched on on the cable box, so I could fumble my way through the menus while the lady told me what each menu selection was.
