It turns out that this model has a keyboard lock option. This is
normally implemented by pressing a buton on the remote. To unlock you
have to hold the menu button in for ten seconds. The really odd think
here though is that the customer tells me that he doesn't have a remote
and hasn't for some time. Is there any other way you might think of,
that this problem might have come about short of two power surges or
brownouts perhaps. The first scrambling the micro and putting the set
into a state where it would not turn off, and the second or most recent
one locking the keyboard? Thanks, Lenny.
