QRD SPARK N5 Controller Repair Tutorial
Disassembly, Assembly, Shoulder Button Replacement, and Front Shell Replacement Guide
1. Preparation
Before starting, please power off the controller completely and disconnect all cables.
Prepare the required tools:
A small Phillips screwdriver, a plastic pry tool, tweezers, and a clean work surface.
Important:
Please keep all screws and small parts organized during the repair process to avoid losing or mixing them.
Caution:
Do not use excessive force when opening the shell. Internal cables, buttons, and plastic clips may be damaged if pulled too hard.
2. Removing the Rear Shell
Place the controller face down on the table.
Use a small Phillips screwdriver to remove all screws from the rear shell.
After removing the screws, insert a plastic pry tool into the gap between the front and rear shells.
Carefully release the clips along both sides of the controller.
Slowly separate the rear shell from the front shell.
Do not pull the rear shell away too quickly, as internal wires may still be connected.
3. Disconnecting Internal Components
Check the internal layout before removing any parts.
Carefully disconnect the battery cable and motor wires if they block the repair process.
When disconnecting cables, hold the connector instead of pulling directly on the wires.
Avoid touching the circuit board with wet hands or metal tools to prevent short circuits.
4. Removing the Main PCB
Remove the screws securing the main PCB to the front shell.
Gently lift the main PCB from the shell.
Pay attention to the joystick caps, button contacts, ribbon cables, and vibration motor wires while lifting the PCB.
If the PCB does not lift easily, check whether any screws or cables are still attached.
5. Removing Front Shell Components
After the PCB is removed, the front buttons and silicone conductive pads can be taken out.
Remove the D-pad, ABXY buttons, function buttons, and any small decorative or support parts from the front shell.
Remove the silicone conductive pads carefully and keep them clean.
The silicone pads must be reinstalled in the correct direction, otherwise the buttons may not respond properly.
Remove the joystick caps if they need to be transferred to the new shell.
6. Removing the Touchpad / Front Shell Module
Remove the touchpad-related parts from the front shell.
If a ribbon cable is attached, handle it carefully and avoid bending it sharply.
Keep the touchpad board, ribbon cable, and plastic support pieces in order for reassembly.
When replacing the front shell, all reusable parts must be transferred from the original shell to the new shell.
7. Removing Shoulder Button Parts
Remove the shoulder button components from the left and right sides of the controller.
This includes the L1/R1 shoulder buttons, L2/R2 trigger parts, springs, and support brackets if applicable.
Pay close attention to the position of each spring and pivot point.
The shoulder buttons must move smoothly and return automatically after being pressed.
If a shoulder button is stuck, loose, or broken, replace the damaged part with a new one.
8. Installing New Shoulder Button Parts
Install the replacement shoulder button parts into the correct left and right positions.
Make sure each trigger spring is seated correctly.
Press each shoulder button several times to confirm smooth movement.
The button should rebound naturally without sticking or rubbing against the shell.
If the button feels tight, remove it and check the spring position again before continuing.
9. Installing Components into the Front Shell
Place the front shell on the table with the inner side facing upward.
Install the touchpad module and related support parts first.
Reinstall the D-pad, ABXY buttons, function buttons, and other front shell buttons in the correct positions.
Make sure all button symbols face the correct direction.
Reinstall the silicone conductive pads over the buttons.
The silicone pads should sit flat and fully cover the button contact areas.
10. Reinstalling the Main PCB
Align the main PCB with the joystick openings, button contacts, and screw holes.
Carefully lower the PCB into the front shell.
Make sure the buttons and silicone pads do not shift during installation.
Check that all cables and ribbon connectors are positioned correctly before tightening the screws.
Reinstall the PCB screws and tighten them gently.
Do not overtighten the screws, as this may damage the plastic screw posts.
11. Reconnecting Cables
Reconnect the battery cable, motor wires, and any ribbon cables that were removed earlier.
Make sure each connector is fully inserted and securely seated.
Arrange the wires neatly inside the shell.
Do not allow wires to pass over screw holes, clips, or moving trigger parts.
Improper cable routing may cause the shell to close incorrectly or damage the wires.
12. Closing the Controller Shell
Place the rear shell back onto the controller.
Check that the shoulder buttons, triggers, and internal wires are correctly positioned.
Press the front and rear shells together gently until all clips are aligned.
Make sure there is no visible gap between the two shells.
If the shell does not close smoothly, stop and check the internal cable routing and button positions.
13. Reinstalling the Rear Screws
After the shell is fully aligned, reinstall all rear shell screws.
Tighten the screws evenly.
Do not use excessive force, as overtightening may strip the screw holes or deform the shell.
14. Final Function Test
After assembly is complete, press every button to confirm normal movement.
Test the D-pad, ABXY buttons, joysticks, L1/R1 shoulder buttons, and L2/R2 triggers.
Check that the shoulder buttons rebound correctly and do not get stuck.
Power on the controller and test the connection.
If any button does not respond, reopen the controller and check the silicone pad, cable connection, and PCB alignment.
