I have Pi 5, and am trying to use the 7" touchscreen. I did buy the Rpi 5 display cable ( https://www.sparkfun.com/products/23683). I am powering my pi with a 25 watt power supply (5V, 5A) via the USB-C port. I plugged a jumper from pin4 on the pi to the 5V pin on the screen's PCBA, and from pin6 on the pi to the GND pin on the screen PCBA. Unfortunately, the screen is not powering on when I boot up the pi. I checked the power pins on my screen's PCBA with a multimeter (Fluke 115) and I do read that the pins are seeing 5V from the pi, but still the screen is not powering on. I even tried powering the screen with a USB-micro cable but still cannot get the screen to power on. Could I have a bad screen? Am I missing something? Does nyone have any suggestions? Thanks!
