Hello, I have a new Raspberry Pi 5 with 4 GB of ram,with an official Raspberry Pi 7inch touch screen.
I have followed the instructions here
https://kksb-cases.com/pages/assembly-instruction-kksb-raspberry-pi-5-7-inch-touchscreen-case I cannot get the screen to even power on. I even used just the 5v and ground gpio pins only.
I even unplug all 4 gpio pins when I read the raspberry Pi 5 only needed the 5v and ground. Then I tried to power on the screen with a micro USB cable using a 3 amp ac adapter.
I have checked YouTube, Google, this discord help and facts section.
I have the video ribbon plugged into camera/display 0.
I tried booting LineagOS 21 /Android 14 from usb and edited my boot config.txt and uncommented the part for USB boot. Tried the SD card with 64bit Raspberry Pi OS and still no luck. I typed this all and while checking in on another app lost my post and had to retype all this.
Any help would be appreciated. At this point I think the screen may be defective.
