I have a rPi 4 that died on me, in two stages:

  • First it would only show a yellow screen on HDMI outputs.
  • Then later, it completely stopped outputting HDMI altogether. It seems to be in a reboot loop?

Things I have tried:

  • Replaced power supply.
  • Replaced monitor.
  • eeprom recovery using Ubuntu imager utility to write SD card.
  • eeprom recovery using Mac OS imager utility to write SD card.
  • eeprom recovery via manual copy of eeprom recovery files to FAT SD card.
  • Tried both HDMI output ports (neither shows physical damage.)
  • Created new OS image.

What else can I try before I scrap this unit, and order a new one?

The rPi has been working just fine for a year or so, before this happened out of the blue.

plot-twist: It was a faulty HDMI cable. Apparently they can break down with normal use.

  • Try reflashing the OS. Do the HDMI ports look broken? Jul 19, 2020 at 3:44

    The eeprom will have nothing to do with this. It is more likely a faulty HDMI cable or faulty OS.

  • Also consider using it for something that does not need a screen (web server / vpn / file server etc) - shame to add to landfill if it can be repurposed...

    Write it up as an answer: you were spot on: the HDMI cable is faulty. Thanks! I'm glad I replaced the cable (on your suggestion) before buying a new rPi.
