Hi sabahan,
Welcome to the forum. Did you buy a replacement front panel PCB, on which a VFD module is already mounted, or just the VFD module (i.e., only the glass display)?
When you say "remove the screen" are you referring to (1) removing the front panel from the chassis, (2) removing the front panel PCB from the front panel, or (3) removing the VFD module from the front panel PCB?
