Troubleshooting – Screen Goes Black After Connecting Projection Cable

If the screen goes black when mirroring, but displays a normal data page and returns to normal after a few seconds, this is usually caused by a projection cable or screen issue. Please follow the steps below to troubleshoot:

Step 1. Confirm the projection cable is genuine

• Non-genuine cables may have compatibility or stability issues.

Step 2. Check connectors

• Ensure the connectors on your phone or iPad are clean and free of dust.

• If using a protective case, remove it to prevent poor contact and signal interference.

Step 3. Test with another device

• Connect another phone or iPad to rule out device compatibility issues.

Step 4. Check adapter and power input

• Ensure the adapter is genuine and the input power meets specifications.

• Verify the phone battery is above 30%; charge if necessary.

Step 5. Contact Customer Service if Issue Persists

• If the issue remains after performing the above steps, contact customer service  to request a replacement projection cable. You can submit your request here: Submit a service ticket

• If the problem persists even after replacing the cable, it may be a screen hardware issue.

• Order number

• Product SN code (located on the label between the bicycle legs)

Customer service will arrange follow-up and replacement as soon as possible.
