Raspberry Pi 5 with official 7in Touch screen, screen will not power on

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.

That doesnt seem in properly to me, and try taking it out and cleaning it with isopropyl alcohol

Then try putting it back in, rotating it, or trying the other port.

Thanks I'll try that when I get home later and will report back here.

<@1071178789939331253> thanks it works now. I still have the writing on the cable facing the same way. I then plugged it into the camera / DisplayPort one instead of zero like you said. and found this "The conductors on the cable should face the white housing not the brown clip." On the raspberry pi forums. Powered the pie and the screen immediately started working I know it's a simple mistake on my part but you are a lifesaver. It's been over 2 hours yesterday troubleshooting it I even try the cable both ways I'm curious as to why it wasn't working on camera zero but I'm happy.

Great I'm glad it's working
