Fig. 3 - Side Case Screw

Fig. 4 - Bottom Case Screws

Step 1:

You will need to remove the screws from the sides and

bottom of the case. Remove 1 screw from the two sides and

8 screws from the bottom.

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

them in zip lock or somewhere safe so they're not lost.

Fig. 5 - Back of the Case

Step 2:

Remove the screws from the back of the case.

You only need to remove the screws starting with the one directly

under the 'nd' of the Roland print onto the right side. 6 screws in

total.

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

You may need to loosen the nuts using a wrench. 14mm wrench

or an adjustable.

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

store them in zip lock or somewhere safe so they're not lost.

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 cord on the lower left corner of the board as shown in Fig. 8.

It may be a good idea to even take a picture to remember which cable goes

where, but that is up to you.

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

board. Then remove the main board and set it aside.

Fig. 11 - Using an Exacto Knife to remove LCD cover

Step 4:

Now you need to remove the LCD cover from the front of the case in order

to access the screws which hold in the bad LCD screen.

The method I use to remove the LCD cover is to use an Exacto knife and

first slowly and carefully pry up one of the top corners of the cover. I then

continue to slide the sharp edge along the top of the cover prying it up.

You may also find that using one of the flat head mini screw drivers to also

be helpful in the process.

Just remember to take your time.

Fig. 12 - The LCD cover shown pried up

Step 4 continued:

As you can see in Fig. 12 the LCD cover has double back tape that runs

across both the top and bottom edges. Once you pry up the top edge, it is

just a simple matter of using your hand to slowly pull up the bottom edge.

Remove the LCD cover and set it aside until later.

Step 5:

As you can see in Fig. 13 the LCD cover has now been removed. The LCD

itself is held in by 4 mini screws. Remove these screws using a mini phillips

head screwdriver, then remove the LCD.
