I have a Pi4, I ordered the 10" screen and the PicadeX hat for it (to update my old Retropie cabinet).
I had everything working on the Pi, I received the display and the hat and connected them up and everything powered up fine, retropie ran, games worked etc.
I then 'F4’d to the command line and entered “curl https://get.pimoroni.com/picadehat | bash” as per the instructions and didn’t see any errors.
But now there’s no video when Retropie runs.
So to clarify, there’s video when the Pi boots but at the point you’d get Retropie showing there’s just a blank screen.
If I now press F4 then we’re back at the command line and there’s video again.
(The display isn’t complaining there is no video so I’m guessing there is but it’s just blank, unplugging the hdmi produces the “no signal” box on the display)
Also if I guess where I am in the menus and select a game then I get the initial mame text box that appears before the game runs - that stays on the screen until I quit back out of mame but I don’t see the game.
It’s almost as if text modes work fine but not graphics modes.
I’ve also tried a computer monitor just in case the video is now outside of what the LCD can handle but that doesn’t help.
Anyone any ideas?
