Noritake VFD Pinout??

[X7JAY7X]

I have Noritake VFD with 18 pins but I cannot find a datasheet on it, not even on noritakes website.

The model is CU40025SCPB-U2A

Anyone have any ideas?

I think a better description may be in order. Is it a bare tube (i.e. pins coming out of the glass), or mounted on a board with controller chips, etc.

Maybe you can find a series that is similar, and hope that the interface is the same.

It is on a controller board. I went to Noritakes website and found one similar but the pins were different. I will post a picture of it, maybe that will help.

Here are the pictures, any ideas?

Also, in the corners on the front of the screen it looks burnt, is this normal?

On Noritake's site, http://www.noritake-elec.com/uversion.htm, it sez:
CU40025SCPB-W6J is recommended to replace CU40025SCPB-U1J,
nothing about a U2A. But it sez also that these are intended to be replacements for LCDs. So I think the extra 4 pins (15-18) can be ignored (notice that the land area surrounding those 4 holes is much smaller). Just use pins 1-14 like on any character LCD display. You can download a data sheet if you feel like registering your private info.

Also notice that these suckers draw 330 mA.
