1. Introduction
This manual provides detailed instructions for the installation, operation, and maintenance of the JRY-W58CDT9-AV6 and XY-W58CDT9-AV7 HDMI to LVDS Driver Boards. These boards are designed to convert HDMI input signals into LVDS output, enabling the use of various LCD panels with HDMI-compatible devices. They also feature additional input options like VGA and USB.

2. Safety Precautions
- Always disconnect power before making any connections or disconnections to prevent electric shock or damage to components.
- Handle the driver board with care to avoid static discharge, which can damage sensitive electronic components. Use anti-static precautions if possible.
- Ensure proper ventilation around the board during operation to prevent overheating.
- Do not expose the board to moisture or extreme temperatures.
- Verify all cable connections, especially LVDS, are correct and secure before applying power. Incorrect LVDS wiring can cause irreversible damage to the LCD panel or driver board.
3. Package Contents
Please check the package for the following items:
- JRY-W58CDT9-AV6 or XY-W58CDT9-AV7 Driver Board
- (Optional, depending on seller) LVDS Cable
- (Optional, depending on seller) Power Adapter (12V DC)
- (Optional, depending on seller) Remote Control and IR Receiver
4. Setup and Connections
Follow these steps to connect your driver board:
- Connect the LVDS Cable: Carefully connect the LVDS cable from the driver board's LVDS connector (labeled 'DIP' or similar, typically a multi-pin header) to your LCD panel's LVDS input. Ensure the cable orientation and pinout match your specific LCD panel's requirements. Incorrect connection can damage the panel or board.
- Connect the Backlight Cable: If your LCD panel requires an external backlight power supply, connect it to the appropriate connector on the driver board (often a smaller white connector near the LVDS interface).
- Connect Video Input:
- HDMI: Connect your HDMI source device (e.g., computer, media player) to the HDMI input port on the driver board.
- VGA: Connect your VGA source device to the VGA input port if using this interface.
- USB: The USB port is typically for firmware updates or multimedia playback, not a primary video input.
- Connect Power: Connect a 12V DC power adapter to the DC input jack on the driver board. Ensure the power adapter provides stable 12V DC output with sufficient current for both the board and the LCD panel.
- Connect Control Panel/IR Receiver: If using an external control panel or IR receiver for OSD (On-Screen Display) menu navigation, connect it to the designated header on the board.
Once all connections are secure, you may proceed to power on the system.
5. Operating Instructions
- Power On: Apply power to the 12V DC input. The board should power on, and the connected LCD panel should display an image or a 'No Signal' message.
- Input Selection: The board typically auto-detects the active video input (HDMI or VGA). If multiple inputs are connected, you may need to use an external control panel or remote control (if included) to switch between inputs.
- On-Screen Display (OSD): If an OSD menu is available (via control panel or remote), you can adjust display settings such as brightness, contrast, color, and aspect ratio. Refer to the specific OSD menu options for detailed adjustments.
- USB Functionality: The USB port can be used for firmware upgrades or, in some configurations, for playing multimedia content directly on the display. Consult specific firmware documentation for details.
6. Maintenance
- Keep the board clean and free from dust. Use a soft, dry cloth for cleaning.
- Ensure good airflow around the board to prevent dust accumulation and maintain optimal operating temperature.
- Periodically check all connections to ensure they remain secure.
- Avoid touching the electronic components directly when the board is powered on.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display on LCD panel | No power, incorrect LVDS connection, incompatible panel, no video input. | Check 12V power supply. Verify LVDS cable connection and pinout. Ensure LCD panel is compatible. Connect a video source to HDMI/VGA. |
| Garbled or distorted image | Incorrect LVDS cable connection, incorrect resolution/timing, faulty LVDS cable. | Double-check LVDS cable pinout and connection. Ensure the input resolution matches the panel's native resolution or is supported by the board. Try a different LVDS cable. |
| 'No Signal' message | No active video input, faulty video cable, source device not outputting signal. | Ensure video source is powered on and outputting a signal. Check HDMI/VGA cable connections. Try a different video cable or source. |
| Board not powering on | Faulty power adapter, incorrect voltage, short circuit. | Verify power adapter output is 12V DC. Check for any visible damage or short circuits on the board. Try a different 12V DC power adapter. |

9. User Tips
- LVDS Compatibility: Always confirm the LVDS interface type (e.g., single channel 6-bit, dual channel 8-bit) and pinout of your LCD panel before connecting. Mismatched LVDS cables or pinouts are a common cause of issues.
- Panel Voltage: Ensure the driver board is configured for the correct voltage required by your LCD panel (e.g., 3.3V, 5V, 12V). Some boards have jumpers for this setting.
- Firmware Updates: If experiencing compatibility issues with a specific panel, check if a firmware update is available for your board model. Firmware updates often add support for new panels or fix bugs.
- Power Supply Quality: Use a high-quality, stable 12V DC power supply to avoid flickering or instability in the display.
