Fig. 4 - Bottom Case Screws

Step 1: UNPLUG THE UNIT BEFORE YOU BEGIN!

To remove the bottom of the case you will need to remove the

screws from the sides and bottom of the case. There is 1 screw on

each side and 8 screws on the bottom. These screws are shown

circled in the photos above labelled Fig. 3 and Fig. 4.

Be sure to make note of which screws go where and store

them in some manner so they do not get lost.

Step 2:

Remove 6 screws from the back of the case.

These are circled in the Fig. 5 photo above.

You will also need to remove the plastic nuts from the 1/4"

sockets on the back of the case. You may need to loosen the nuts

using a wrench. A 14mm or 9/16” wrench or an adjustable wrench

can be used to loosen these nuts if needed.

Once again be sure to make note of which screws go where and

store them so they're not lost. Since there are multiple different

types / sizes of screws, it is a good idea not to mix them up.

Personally, I used separate zip lock bags for each section of the

process in this guide.

Step 3:

Now that the case is opened locate the main board. This is the circuit board

with all of the ribbon cables connected to it shown in Fig. 6.

Disconnect all of the ribbon cables from the main board. Some of the

connectors need to be unlocked as shown in Fig. 7 you must pull up on

both sides of the connector to unlock and remove the cable. You will need

to cut the zip tie on the lower left corner of the board shown in Fig. 8.

After removing the cables, remove the three screws holding the main

board in place. Then remove the main board from the case and set it aside.

Fig. 13 - The LCD cover shown pulled up

Step 4:

You will need to remove the LCD cover from the front of the case in order to

access the screws used to mount the original LCD screen in place.

There are multiple ways to accomplish removing the front LCD cover. You may be

able to remove the LCD cover using a thin pry tool and prying up one of the top

corners of the cover as shown in Fig. 11 and then slide the edge along the top of

the cover to pry it up. You may also be able to press the cover out by pushing on

the backside of the cover using a plastic tool. This is shown in the Fig. 12 photo.

As shown in Fig. 13 the LCD cover has been pulled up and you can see the double

sided tape that runs across both the top and bottom edges. Once you pry up

either the top edge or the bottom edge you should be able to slowly pull up the

other edge by hand.

Do not use excessive force while attempting to remove the cover. It is best to use

plastic tools if possible to prevent scratching the finish of the case or plastic

cover. I personally have used a thin metal pry tool on multiple occasions when

removing the LCD cover without causing any noticeable damage.

Remove the LCD front cover and set it aside until later.
