Picade 10" display not working

Hi, good evening folks.

I bought a 10" Picade recently and I’m having trouble getting the screen to work. When everything is connected and I power up, ‘HDMI’ appears in the top left and then the screen says ‘No signal’ and powers down after a few seconds.

Things I’ve tried so far:

  • Added hdmi_force_hotplug=1 to config.txt
  • Powered the screen display board from a separate power supply
  • Unplugging and re-plugging in the display cable, cleaning connectors with an alcohol wipe
  • Tried to connect various devices (Nvidia Shield, Amazon Firestick, RPi 3, RPi 4 etc.) to it and none of them work

I’ve toggled the DVI / HDMI setting in the LCD screen menu but that didn’t work either.

I’ve exhausted all my options I think. I’ve spent the best part of the day debugging the problem and I think it’s either a faulty panel, LVDS cable or display board.

Any ideas?
