There is no need to remove the backbox monitor to remove the head. All connectors are easily accessible below the monitor. If you need to remove the monitor for some reason, consult the last section.

This picture shows what you see behind the monitor to get you oriented. We will proceed from left to right.

Step 0:

Before doing anything, make sure the machine is turned off.

Step 1:
The first step is to disconnect the cabinet speaker from the amplifier on the left. Remove the top black and purple cables going to W- and W+.

Step 2a: 
Remove the vertical J5 connector in the lower left corner of the center breakout board. Push that single wire loom out of the way.

Step 2b:
Remove the horizontal J31 connector in the lower left corner of the breakout board.

Step 2c:
Remove the small vertical J24 connector close to the center of the breakout board.

Step 2d:
Remove the ribbon cable from the lower right corner of the breakout board.

Step 3:
Remove the 3 USB cables and the ethernet cable from the main motherboard. There is no need to label the USB cables since they can go in any USB slot later on. Make sure you press on the latch clip to release the ethernet plug.

Also remove the HDMI cable from the lower right corner of the video card.

 

Step 4:
Remove the small cable in the lower right corner of the PD-LED board.

Step 5:
Untangle all the wires coming out of the large loom. Everything should be already disconnected. Push the large loom down out of the way.

Step 6:
Remove the two bolts holding the hinge in place. There is a metal washer on the inside, and a plastic washer between the hinge and the cabinet.

If present, also remove the two safety bolts going through the hinge underneath the backbox.

The head is now removed.

Appendix: How to Remove the Head Monitor

There is no need to remove the backbox monitor to remove the head. If you need to remove the monitor for some reason, here are the instructions. If you need to remove the head and the monitor, might as well remove the monitor first.

Step A1: 

Remove the power supply cable and DVI cable for the display. It may be helpful to loosen the nuts (Step A2) if you need additional clearance. Using a mirror or your phone's camera is helpful.

Step A2:
Remove the four ⅜” nuts holding the monitor on. The monitor can be removed and placed in a safe space.
