Perform a microSD Card Format and Factory Reset

A corrupted file system or improper video codec rendering can cause green or black screen playback.

Caution: Formatting erases all files on the microSD card. Back up important recordings before formatting.

1. Format the card using the instructions for your model:

  • U3000 PRO or Q200: Connect in THINKWARE DASH CAM LINK, then tap:
    [Dash Cam Settings] → [Memory Card Settings] → [Formatting Memory Card] → [Format]
    Then tap [Confirm] on U3000 PRO or [OK] on Q200.
  • U3000: Press and hold [REC] + [Wi-Fi] together for 3 seconds.
  • LCD models: Go to [System Settings] → [Format].

Caution: Keep power connected until formatting finishes.

For formatting methods by model, see How to format your microSD card.

 

Caution: A factory reset erases all files on the microSD card and restores factory default settings. Back up important videos before you reset.

2. Follow the reset method for your model:

  • U3000 PRO, U3000: Press and hold the REC and MIC buttons together until the dash cam beeps.
  • Q200: Press and hold the Wi-Fi and REC buttons together until the dash cam beeps.
  • LCD models: Use the reset option in the on-screen settings menu.

For reset buttons and menus by model, or if the reset does not work, see How to Reset your Dash Cam.

 

Compare Image Quality across Vehicles

Note: Testing in a different vehicle or with an alternate power cable helps you check whether a white or green display changes with the vehicle electrical supply.

1. If your front camera displays a fuzzy white screen, solid green screen, or black screen while audio continues to record normally, temporarily connect the unit in another vehicle.

2. If the white or green display continues with different vehicles or wiring, contact THINKWARE support for further assessment.

 

None of the above worked

If you have checked resolution, cleaned the lens, tested HDR and Super Night Vision, formatted the microSD card, and checked audio settings, but the issue continues, please contact THINKWARE support.
