Phil: That sounds like the Laser Etched number engraved on the FBT. Sometimes that is ok, but I would say not this case. Is there a White Sticker somewhere on it with numbers? You may have to actually remove the FBT in a lot of Cases to see this Sticker. If there is an FCC ID on the Monitor it may help too.
