Troubleshooting Guide and Warranty

Troubleshooting Guide

• This page deals with problems that can be corrected by a user. If the problem still persists after you have tried these solutions, please contact customer support.

Failure in writing system

The monitor displays black or white screen or no full screen or showing

white line

|

Make sure your image system is intact. Modify the configuration file config.txt.

The monitor flicks

| Ensure sufficient power. Make sure the screen micro USB and Raspberry Pi USB connection is stable and try using another USB cable.

Make sure the power adapter is 5V3A when used with Raspberry Pi 4. Power the monitor with one more USB cable and power adapter.

Touch Screen Issue

| Make sure the Micro USB connector is properly connected between the USB ports of the Raspberry Pi and the Touch interface of the LCD screen. Try another micro USB cable (supports data transfer).

Please note that one end of the touch cable needs to be connected to the Touch port of the monitor and the other end to the computer equipment, host computer, Raspberry Pi and other HDMI devices.

When the monitor is connected to a game device or the monitor’s touch end is connected to a power source, socket, or other power supply device, the touchscreen doesn’t work.

The LCD cannot display normally when connected to PC| Adjust the output signal to HDMI. Make sure the operating system is Windows. Use the LCD as the only monitor for testing. Connect the USB power cable first and then the HDMI cable. Try to restart your computer.

The volume is too small

| Considering the power supply voltage, we limit the maximum volume, so the sound is not so loud. If you need a loud volume in some situations, it’s recommended that you can connect an external mini speaker to amplify the

sound.
