My RPi 3 will not boot even after I have looked at every possible trouble shooting technique I could find. I plug it into the power and all it does it turn on the red led. I had it working for some time, but now it refuses to turn on. I've now tried 3 different power sources and 3 different SD cards and all have ended in the same result of it not booting. It gave me this same problem when I first got it, but after the 3rd SD card it seemed to have worked itself out. The current power supply and SD card are from Adafruit, so I trust that they are of decent quality. Could this be a problem with the manufacturing of the RPi? I've refused to believe it is, but I don't know what else it could be.
To double check,
- Wait a day or two before trying to power up the pi again.
- When booting, make sure all peripherals are disconnected.
- Im not completely sure what you mean by "Got it working" does this mean you had successfully booted?
- Are your SD cards more than 8GB of memory?
- If you have the Raspberry Pi 3B+, try booting the raspberry pi from a USB drive as they might be something wrong with the SD card holder in the Pi.
I hope those basic troubleshooting techniques get you somewhere.
Use SD Formatter to clear the SD card. Get a fresh image and use Win32diskimager to write to the card or grab PiBakery.
Power the Pi on with the SD already inserted. Do you get the rainbow splash on the display? The 4 Raspberries (one for each core of the CPU)?
The USB boot option requires the Pi already have USB boot enabled.
"Are there any common causes to having this?" Yes, but there are no "official statistics" published about power problems in one place.
But if tell I have personally destroyed my SD by turning the power off on RUNNING system it will be ignored , edited or deleted.
However, any causal observer of this forum can detect few problems related to "strange behavior" which can be traced to power issues. Of course majority of users cannot or do not want to look at "whole picture" or get stuck on "answers" likes - get a bigger SD.
