    Isn't that the optical light for optical audio? Maybe the optical audio was turned on for some reason.

    That's the optical audio output, and something turned it on somehow. Or sometimes if you have an optical audio plug connected to the jack and you remove it, the system won't automatically turn off the optical signal as it should...usually re-plugging and wiggling things around a little will fix that.
