Pi 4 won’t respond. Red light solid, green light stuck consistently flashing
Hi guys! I’ve created an automated hydroponics setup in my greenhouse and using a Pi 4 to control it. I ran some equipment tests with it for a few hours and it had no problem booting up, connecting to internet and running code. The next day I went to ssh into it, my computer couldn’t find it and I noticed the green light stuck flashing at a consistent rate (about 5 or 6 times a second) forever and the red light solid. I then tried to plug into a monitor to see more info, but all my monitors detect no signal coming from the pi and I don’t believe it’s connecting to WiFi because I can’t ssh into it so I’m stuck.
Couple of things I’ve tried:
1: Completely disconnecting everything except power from Pi
2: Re-formatting/re-imaging micro SD with RPI
3: Ensuring appropriate power supply
4: Reformatting/ installing EEPROM on micro SD with RPI
All to no avail. ChatGPT is telling me there’s likely a hardware issue. Any help would be greatly appreciated!
