Thanks very much for replying -- I can see what appears to be two pairs
of
semicircular pads facing each other -- one pair on top of the board and
one
pair on the bottom of the board (right on top of each other, as it
were).
It doesn't look like there is a solder bridge on either of them,
though.
The pads are right next to the wider of the two ribbon cable
connectors.

I found that the DVD player (a DVP-NS300) would power up if the
narrower
ribbon cable was disconnected. It wouldn't work, but it would get out
of
standby.
