I presume you completely unpowered the box, preferably by removing the
power cord for 30 seconds or so. If you didn't, there's a chance some
device on the motherboard got upset during the power glitch and hasn't
been reset since. Other than that, I dunno, unless something was
permanently damaged. Wish I could be more helpful.
