Nitro - it's a disk error code. Here is a discussion on the issue:

If you find that you can not resolve the issue, please let me know. I may be able to put you in touch with someone who can help. Also, if the camera is beyond hope (which I don't think is the case), let me know as well. I have an FD90 that I need a new LCD for - they all use the same LCD.
