Got Picade kit recently and finally setup today.
All went well until I turn it on.
The pi and screen turn on but its just white on the display - photo attached.
Retropie has been installed ( but no games yet). The pi is OK as it boots into retropie when attached to TV via HDMI. I changed config re HDMI force as per tutorial.
Attached photo of back of display.
Any ideas? Many thanks.
Edit. New user so can’t upload photos.
