Question: Using the Raspberry Pi image provided by the CD/net disk, cannot use the LCD normally.

Answer:

Confirm that the hardware connection is correct and the contact is good.

Determine whether TF card is normal and whether the system is started normally.

The PWR lamp is always bright when the Raspberry Pi is started, and the ACT light is flashing.If you find both lights on,

it may be the TF card does not successfully burn the image file,or that the TF card is not in contact with the Raspberry Pi.

Recommend using 5V 2A power adapter to power the Raspberry Pi.

If you use a computer USB interface, you may not be able to activate the Raspberry Pi due to insufficient power supply.

Question: What is the reason for the LCD not displayed using the image provided by the Raspberry Pi official?

Answer:

LCD needs to be installed driver to display correctly, please refer to "How to install the LCD driver (En)" related documentation.
It is recommended to use the image file provided by us first to test. After the test is passed, use the image file of Raspberry Pi official and installed the driver.

Question: How to switch back to traditional monitor for display?

Answer:

Please refer to "How to install the LCD driver (En)" related instruction document, and use the following command:
```
sudo ./LCD-hdmi
```

Question: Why the LCD works but flickers?

Answer:

This problem is likely due to insufficient power supply.
If you are using the Raspberry Pi, please use the power supply of 5V full 2A to power the Raspberry Pi,

and connect the Raspberry Pi and the LCD by the short USB cable we provided.

If it is used as a computer monitor, do not use poor quality USB cable or extension cord connection,

do not receive extend the USB port to get electricity, please use the USB cable we provided.

Question: Why the Raspberry Pi unable to work properly after updating the Raspbian system?？

Answer:

The update needs to be done in the following manner, otherwise the image cannot run:

sudo apt-mark hold raspberrypi-bootloader
sudo apt-get update
sudo apt-get upgrade

Question: Why the LCD is connected to the computer HDMI, but cannot be displayed normally?

Answer:

Make sure the HDMI interface of the computer can be output normally.

The computer only connects to the LCD as a display device, and does not connect to other monitors (unplug other monitors).

Connect the USB first, then the HDMI.

Try to restart your computer.

You must use the Windows operating system.

Question: How to turn on the Bluetooth function on the Raspberry Pi?

Anwer:

Method 1: upgrade to the official latest image of the Raspberry Pi (the Bluetooth function has been turned on by default after 2016-05-27-raspbian-jessie);

Method 2: manually turn on Bluetooth.

sudo apt-get install pi-bluetooth
sudo apt-get install bluetooth bluez blueman 
systemctl status bluetooth
sudo systemctl start bluetooth
sudo reboot

Question: Why unable to display full screen or incomplete when using 5”, 5”-B, 7”-B, or 7”-C HDMI screen?

Answer:

Check if the HDMI is plugged in and output is normal.
Open the config.txt file in the TF card root directory to check the HDMI configuration.

5", 5"-B and 7"-B 800*480 should be configured as follows:

hdmi_group=2
hdmi_mode=1
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0

7"-C 1024*600 should be configured as follows:

hdmi_group=2
hdmi_mode=1
hdmi_mode=87
hdmi_cvt 1024 600 60 6 0 0 0
