Raspberry Pi 4 will not boot

Post by gragib »

I purchased a Raspberry Pi 4B from Adafruit last month. I used it with the official Raspberry Pi USB-C power supply (white version of #4298) and the 1.3" TFT bonnet (#4506).

It worked well for about 2 weeks. Yesterday, it was unable to initialize the SPI display reliably (only worked every 4th or 5th power cycle). Today, it will not boot up at all.

Everything works fine if I use the same power supply, bonnet and microSD card with my Pi 400, which leads me to suspect that something is wrong with the Pi 4.

The Force is not with this Pi 4B. :(

What next steps can I take?

Thanks in advance.

Have you tried to reimage the SD card yet? Run it with nothing connected and see what happens.

Thanks for the suggestion. Here are the things I have tried:
  • run with power, bonnet and ethernet connected
  • run with power, HDMI and ethernet connected
  • run with power and bonnet connected
  • run with power and HDMI connected
  • run with power and ethernet connected
  • run with power connected (the Pi 4B temperature does not change)
  • replace SD card
  • replace power supply
All of these work on the Pi 400, but not on the Pi 4B.

During all this, only the red LED near the USB C port is illuminated solid.
