RC070 : 7 " LCD Display - Screen with Raspberry PI 4 keeps turning on and off

rlopez

Hi there!
Recently, I bought the Elecrow RC070 and connected it as described in the wiki page https://www.elecrow.com/7-inch-1024-600-hdmi-lcd-display-with-touch-screen.html
After configuring the following code in the Raspberry Pi's config file:

hdmi_group=2
hdmi_mode=87
hdmi_cvt 1024 600 60 3 0 0 0
hdmi_force_hotplug=1

Is this configuration correct, or do I need additional setup on the Raspberry Pi side to prevent the display from turning on and off while the Raspberry Pi 4 is working?
Thanks

Jennie

Hello @rlopez ,
I'm sorry to hear that you’re experiencing issue. Let’s try a few troubleshooting steps to resolve this:

1. Check the HDMI connection:
   Ensure that the HDMI cable is firmly connected to both devices.
   Try using a different HDMI cable or adapter, as sometimes the issue can be related to a faulty connection.

2. Power supply:
   Confirm that the screen is receiving adequate power. If the screen has an external power source, ensure it is connected and functioning properly.

3. Update the Raspberry Pi firmware:
   Make sure your Raspberry Pi is running the latest firmware. You can update it by running the following commands in the terminal:

   sudo apt update  
   sudo apt full-upgrade  
   sudo rpi-update  
   

4. Update the newest Raspberry Pi's image. There might be some improvements or bug fixes related to display compatibility.
