For OEM NBT screens showing static, distorted images, partial image corruption, or continuous flickering.
Quick Answer
If your MINI OEM NBT screen flickers, shows static, displays only part of the image, or looks corrupted, first identify whether the original screen is NBT 6.5-inch or NBT 8.8-inch. Then check the vehicle model, camera format, parking brake setting, original car resolution, and LVDS connection in the order below.
| Symptom | Check first |
|---|---|
| Static or corrupted image | Original car resolution |
| Continuous flickering | Resolution refresh and LVDS connection |
| Partial or incorrectly sized image | NBT 6.5-inch or 8.8-inch selection |
| Flashing red light inside the LVDS decoder | OEM head unit operating status |
1. Identify the Display Problem
A normal NBT display should be clear and complete, with the correct position and aspect ratio. There should be no static, ghosting, image corruption, or continuous flickering.
2. Identify the Original NBT Screen Size
- NBT 6.5-inch: The display is narrower, with wide plastic bezels visible on both sides.
- NBT 8.8-inch: The display is wider and extends closer to both sides.
3. Check the Basic Settings
3.1Check the Vehicle Model Configuration
Settings → Factory → Enter password 8888 → Change Model
Select LuZheng (LZ) → BMW → BMW keep the original car host, and then tap Save.
3.2Check the AUX/Right Camera Format
Settings → Reverse and AUX → AUX/Right Camera Format
Select AHD 720P30. If it is already selected, do not change it.
3.3Turn Off Parking Brake
Settings → Common → Parking Brake
Set Parking Brake to OFF.
4. Set the Original Screen Resolution and Backup Type
Car Set → Vehicle Settings
4.1 Original Car Resolution
| Original screen | Required resolution |
|---|---|
| NBT 6.5-inch | NBT 800×480 |
| NBT 8.8-inch | NBT 1280×480 |
4.2 Backup Type
- If an aftermarket reversing camera is installed, select Install Reversing.
- If the vehicle uses the OEM reversing camera, select The Original Car Is....
5. Force the Resolution Data to Refresh
The unit is preset according to the customer's order before shipment. Even if the correct resolution is shown, the data may not have switched completely. Perform the following refresh:
- Under Original Car Resolution, temporarily select a different resolution.
- Switch back to the correct resolution: NBT 800×480 for a 6.5-inch screen, or NBT 1280×480 for an 8.8-inch screen.
- Only change the resolution. Do not change any other setting on this page.
6. Return to the OEM NBT Screen and Test
- Tap the vehicle icon at the bottom of the screen to return to the OEM NBT interface.
- Check whether the image is now clear, complete, and stable.
| Result | Next action |
|---|---|
| The display is normal | The problem is resolved. The unit can be used normally. |
| The screen still shows static, distortion, or flickering | Continue with the LVDS wiring check below. |
7. Check the LVDS Connection and OEM Head Unit
- Make sure the vehicle's OEM LVDS connector is correctly and firmly connected to the NBT LVDS decoder box.
- Look inside the decoder box for a flashing red light. If the red light is flashing, the OEM head unit may not be operating.
- Keep the vehicle powered on. Disconnect the OEM LVDS cable from the decoder box and plug it directly into the original screen. Only the LVDS cable is required for this test; the other connectors do not need to be connected.
- Check whether the original screen displays the OEM NBT system.
| Test result | Diagnosis and action |
|---|---|
| The OEM NBT interface appears | The OEM head unit is outputting a video signal. If the product screen remains abnormal, contact our engineer for further assistance. |
| The OEM NBT interface does not appear | This confirms that the OEM head unit is not operating correctly. Perform the sleep-and-restart procedure below. |
Allow the Vehicle System to Sleep and Restart
- Disconnect the OEM LVDS cable from the original screen and reconnect it to the NBT LVDS decoder box.
- Turn off and lock the vehicle. Wait 30 minutes for the vehicle system to enter sleep mode completely.
- After 30 minutes, start the vehicle again and check the OEM NBT interface.
Frequently Asked Questions
Why does my MINI OEM NBT screen flicker or show static?
