I have an old 80s 2x40 VFD unit that has a TDK power supply. it looks like a pull from some equipment, but i have no idea. I cannot get the power supply module to start, but i dont know the orignal voltage.
I tried 5v, and I tried 12v. tried 24v. wont start. I need to find some data on this power supply board, but i am comming empty. its a TDK module with these markings:
KU-3294V-OT PCU-669 and a sticker that says CE-2103 TDK japan.
any ideas? Thanks.
Here is a pic of the entire assy:
