I recently pulled two S905X-CC out from storage after about two years, and after properly flashing a couple SD cards attempted to boot them. Both units only show a solid red and blue light. I’ve verified 3 different power supplies from inland and canakit and the GPIO is showing 5.5v for all of them, however there is no USB power and no HDMI output. I verified three different branded SD cards on a Rasberry Pi 3B+, all booting successfully there.
Is there any way to test if the units are dead? Though I’m at a loss for how they would die in esd bags.
