Maybe some of the dvd points got loose in the mail.
U will still get menu, u can still upgrade firmware by pressing and holding the power button, and it will also boot original games US (if console is US) if some of those wires are loose.
Those wires is used for booting media, and hence, backup wont work.
If this is a PAL console and USA games original plays fine, then ur doing something wrong during backup.
What happends if u try backup?
Does it come to "PLEASE INSERT PS2 DISC" very very fast?
If yes, wrong way to burn or dvd point loose.
