I think that the MK1 and MK2 VFD units are similar but not exactly the same. At least on mine, the "fill nipple" was in a different place. Don't know if that means anything.

The following entry in the FAQ is geared toward the MK2, but perhaps might help you with the MK1 if you take into account that all the electronics will be different:

Also make sure you didn't break off or damage any components on the back side of the MK1 display board. For instance if trying to pull out hard drives the wrong way.

When dismantling the player, always follow the instructions carefully.
