Please add more info about your setup, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.

What kind of display are you trying to install - can you add some info about it and from where you got the drivers ?

@mitu actualy i dont know about the model of lcd. But it looks like to this. http://www.lcdwiki.com/3.5inch_RPi_Display

I'm using rpi 4 2gb . I installed latest raspbian os add the drivers as show in the above link. But after the command LCD-show, Pi is automatically restarted and stuck in boot screen. tft display shows only a white screen. but i can ssh to the pi. Hoe to fix this

@zord96 You can probably fix the video breakage by editing /boot/config.txt and removing the lines that the driver script added (the original files should have a backup in the /boot folder).

Try using the drivers from https://github.com/swkim01/waveshare-dtoverlays for the display, instead of the ones from goodtft/ LCD-Show .

@mitu can you please explain it further..

I flash a fresh os into sd card. Then, first install git clone https://github.com/swkim01/waveshare-dtoverlays.git this.

then as in the link i used sudo cp waveshare-dtoverlays/waveshare35a.dtbo /boot/overlays/ this command, but it says that cant find a directory. Still tft is white color

@zord96 How did you download the waveshare-overlays folder ? Did you use git from the command line or you downloaded the repository as a zip file ? Your current folder, from where you execute the the cp command, should have a waveshare-overlays folder.

@mitu i used the git command and i used cp in the /boot/overlays as root
