Help NEC NP-U250XG projector serial number format
Help I want to extend the warrantee on some NEC NP-U250XG projectors that were installed during the summer when I wasn't here. I can't find the serial no on the case I guess it is under the mounting plate but I can get a serial no from the information screen on the setup menu. Unfortunately the NEC website doesn't like the format of this serial no. I guess it wants some leading zeros or sn or something that I haven't been able to guess. An example of the serial number I have is 128. Can any kind person tell me what I need to add to this to make it a valid serial no?
