I have a 0038 in a Silverstone GD01 and failed to switch off the
backlight, too.  I don't use LCDd, but my own driver program (in order
to have full graphical access), but got the commands from the LCDd
source, IIRC.

(And the machine did not switch it off in standby mode, either.  But
then, Linux fails to wake up anyway (darn!), so I currently cannot use
standby.)

Something else failed but I don't remember exactly.  Maybe there are
different backlight brightness settings?  If so, that failed, too.
(But contrast settings work.)
