  • Very new, but will try another. Pi was in an enclosure behind a 5x7 touch screen. Seemed to run hotter than the Pi-4 Commented Feb 27, 2023 at 17:21
  • Running hotter than a Pi 4 doesn't sound good. So it currently fails to boot with any SD card, including one with a fresh image of Raspberry Pi OS? What currently happens with the lights on startup - the number of flashes of the red light is important. Add that info to the question. Also if possible compare the behaviour with another Raspberry Pi 2 if you have one. Commented Feb 27, 2023 at 20:55
