Why Is My LONGER RAY5 10W Touchscreen Not Responding?
Exact model: LONGER RAY5 10W
Safety: Disconnect power before opening the controller or laser head. Use wavelength-appropriate laser eye protection for testing.
A.
Start with the accessible checks
What this suggests: For an unresponsive RAY5 touchscreen, separate display touch-panel damage from a whole-controller power or firmware issue.
What to do
- Disconnect power, remove any protective-film interference and verify other controller functions still respond.
- LONGER's model-specific service instructions describe removing the controller housing M5 fasteners, the rear cover's M2 screws and the screen assembly's M2.5 screws, then installing the correct replacement touchscreen and reseating its ribbon connector.
- Do not pull the ribbon by its conductors or mix up screw lengths.
Still not fixed? Continue to the next check.

If the problem remains after the first checks
What to do
- If firmware is implicated, use only the exact RAY5 10W board/revision firmware.
Confirm the repair
Touch areas respond correctly and the device boots and runs a safe non-laser motion test after reassembly.
