Disassembly Notes
To remove the Rear Panel, remove the two screws at the back of the top cover and the two at the bottom corners of the rear panel.
You may then separate the Top Cover; it is held on by two screws on each side, under the overhang. Rotate the cover up and slide it off towards the display.
For the Logic Board, first unplug the two cables, the remove the four screws at the corner. You may remove it without removing the top cover.
The CRT driver board (TV Monitor Board) is attached to bottom of case with four plastic standoffs. Pinch them from the bottom to remove them.
