Curious if it’s a known issue or just my own user error… Iv lost count on how many times iv flashed a new rpi OS, follow the one line install or github repo manuel install and each try after a few minutes the display goes black. This doesn’t accure when I replicate the install on a pi 4 though. All help is appreciated,
Thank you.
Same thing is happening to me, but it’s more like a few seconds after starting up. My desktop loads, then 1 second later it blanks.
I’ve had the same issue with my HyperPixel4 on the Pi 400.
I have the Hyperpixel plugged into the GPIO on my 400 via an Adafruit Cyberdeck and am using the latest Pi OS (I tried the legacy Raspian linked from the Pomoroni Hyperpixel help page but it was so unstable on my 400 even without the Hyperpixel that I went back to the latest build; couldn’t even get to the Hyperpixel installation).
Using the latest Pi build on my 400, when I try to run the recommended install.sh, I get the following results (the touch-function then works, but display doesn’t). The LED lights are on, but no display.
Does anyone else know what I need to do to fix this?
