Replacing the bottom LCD and/or touch screen for Nintendo DS Lite If you are replacing both these screens, you probably don't need to bother separating them. Just skip on down to the 'Installing new screens' paragraph on this step.
You should now have the entire bottom display detached from the PCB. Take careful note how the ribbon cables are oriented.
Now, look at the display edge-on. From the 'top' (touch screen) down, you should see:
-Plastic frame around the touch screen (this should be in the same color as the rest of the shell)
-A very thin section composed of several layers, maybe.
-Clear plastic layer ~1mm thick
-Thin layer of black adhesive (this is the separating layer between the LCD and touch screen)
-Metal cladding around the LCD
Wedge your fingernails directly above or below the black adhesive layer. (You may wish to leave the adhesive layer stuck to the screen that you are not replacing, but I personally pried them apart leaving the adhesive on the touch screen portion.)
If you are very careful, you can use a pointy thing, but preferably not a knife. A flat-head screwdriver might work. Separate the two, and toss out whichever one you intend to replace. |

How to Clean dirty NDS screenCleaning a dirty screen
If the screen on your portable system (including either screen of a Nintendo DS) has visible smudges, fingerprints, or other foreign material, you can clean it by using a soft clean cloth such as a lens or eyeglass cleaning cloth. (If you have noticed that the lower screen on your Nintendo DS has pieces of foreign material, such as crumbs, wedged between the housing and the screen, click on the system you have for specific troubleshooting steps. Note that this does not apply to Nintendo DS Lite.)
Cleaning Foreign Material from the Edges of the Touch Screen .
If your Touch Screen is not responding properly, and you have found foreign material between the Touch Screen and the housing of the Nintendo DS, try the steps below to remove the foreign material.
Tools needed:
A brand-new, soft to medium-bristled toothbrush.
Important Precautions:
1. Do not use any liquid or cleaning solution, as this may damage the system.
2. The touch panel cleaning process should only be performed when foreign material is visible.
To clean the Touch Screen:
1). Hold the Nintendo DS so that the edge of the screen that you need to clean is at the top.

| Opening the zire is pretty easy - just two small Torx screws and a gentle fingernails in the side parting lines will pop it apart - Careful, there's a piezo electric wired into the back of the shell. Then you will see the cct board, and there are two flex-connectors wrapping around the board to the front of the display/touchscreen combo. To top one is a 4 connector - that's the touchscreen connection. If you use a small screwdriver to short either the lowest conductor on the plastic ZIF connector to it's neighbour (on the thing soldered to the PCB into which the flex tab is inserted, while the Zire is on, you will hear the tell-tale click of a touch being recorded. Same if you short it to the 2nd from the top. That confirms for me that the chip knows what to do with signals from the screen - it just isn't getting them. Two possible problems would be either a cracked conductor in the flex cable, or a bad connector. The latter is more common - and usually it is a poorly designed connector that allows oxide build up. |
