Panasonic DMR-EZ-27 won't start

[root]

Following a power outage the unit keeps rolling the oooo...
forever. I can get it to shutoff by holding the power
switch on for a while, but then when I start it the
display reads HELLO and sits there forever.

No help from Panasonic. The manual says the ooooo....
is normal, but not for several hours.

Any ideas?
Thanks.

Thanks for responding, but I couldn't find any mention
of my problem in that link. The "reset" option using
CH-Up+Ch-Dn only works after the unit completes a
power on test.
