Aspen/Sequoia monitor removal and maintenance

Now.. if you wanted to pull off the cosmetic panels on the monitor, you can either leave the monitor on the swivel base, or remove it.

I personally leave it on the swivel base, since it makes life easier when you go to pull the back case off. However, for illustration purposes we've elected to remove the monitor from the swivel base and disassemble the cosmetic panels while it is off the system.

Step 1 -- when the monitor has been removed from the system, put it on a table or bench and allow yourself plenty of work space. If you can work on it with another person (at least until you're familiar with disassembling) this will help further prevent any damage to the cosmetics or CRT/monitor internals.
In the picture below we start by removing the speaker covers:

Step 2 -- once the clip has popped up, you then need to remove it from the plastic housing -- please see the picture below to get an idea as to what's behind the speaker cover and how it is held to the plastic housing -- you will need to repeat the process for the other side of the monitor case:

I've also illustrated where the audio connector and control cable are located - we'll be removing these in the next step (the control cable is only on this side of the monitor).

Step 3 -- to unseat/remove the control cable, pull gently upwards on the yellow wires as a group and it should separate from the main board. The audio connector may have a bunch of glue on it, so twist the audio connection to break the bond, then pull it away from the speaker (hold the audio connection housing, not the cable).

Step 3 -- continued -- there is another audio connector on the opposite side of the monitor. Do the same thing as the previous side -- twist, pull:

Step 4 -- now that both speaker covers are off, you will need to remove the screws holding the back case, to the front faceplate. First you need to identify these screws as seen below:

They have grooves for a flat tip screwdriver, but they can be removed by using a pair of pliers as well, as seen in the next step.

Step 5 -- remove both screws, repeat for the opposite side of the monitor.

The next picture illustrates what has been accomplished so far, and what you should have lying on your workbench.

Moving on to Step 6 -- now that the screws holding the back case to the front case are off, you need to remove the back case. This can be done several ways, but I wanted to illustrate what you want to take notice of before attempting this. Prior to anything else though, find something you can rest the monitor on -- face down, so you can access the bottom. The case has several spots where it connects to the monitor base, they're plastic inserts that slide into grooves. They break very easily if you apply too much force when trying to remove the monitor.

To facilitate a proper removal you will want to slide the back case away from the monitor, then lift up and pull the tabs out/away from the monitor. Please see the illustrations below:

Once you've pulled the back casing away from the monitor, it's time to move on to the faceplate.

Step 7 -- The faceplate has 5 screws in total - 4 of which need to be loosened, the 5th screw holds the ground wire to the monitor chassis and will prevent you from pulling the faceplate off:

Step 8 -- Gently slide the faceplate away from the monitor taking care not to break the small plastic pins that go between the screws and the monitor chassis. You will see two cables connected to a board at the bottom of the faceplate -- these allow control of the system volume, and the 4 gray softkeys, there is also a microphone wire connecting to a microphone. These need to be removed prior to full removal of the faceplate:

After removing the cables, you can pull the faceplate off entirely, as illustrated:

This should complete the monitor disassembly. You can reassemble the monitor by reversing the process.
