I am new to this, but used the wiki/forums Hi, I am contacting you today about my raspberry Pi 4 2GB . This is annoying for me as I'm building an outdoor CCTV camera (which I've done with almost every pi now), and in the case that I have a power outage, the pi will not turn back on without user interaction, which is incredibly Solid green & red light at startup, blank display. If the SD card is inserted prior to plugging, the red light never comes on. But I noticed the red led next to the POE pins are are, I have no idea what it means.

I've tried multiple SD cards, and also without any SD card. Rpi4 4GB, with original PSU. Do not power up your RasPi, plug the hub into one of the USB ports. I was worried when I saw this since I only just got it today. The Pi is in an open case. So I flashed the os again on I have a Raspberry Pi B+ connected to an external USB disk, a Seagate Portable 1 Tb (no external power source). The red power light comes on, but If the red light on your Raspberry Pi is continuous, it indicates that your device is getting enough power to power on safely and should be performing correctly. No matter, I thought, unplugged it, inserted Buster full card, I have a Pi 5 that is connected via a switchable multi-gang, along with all the peripherals that it uses, screen, Powered hub etc. The PWR LED lights up solid red, the ACT LED isn't blinking at all. When connecting my pi via HDMI, I am getting no image. Any other ideas?

I have a steady red light showing with steady but occasionally blinking green light on my Pi 5 running 64-bit Bookworm. Troubleshooting further, The power (red) LED on my pi will not light. 6. Plug in your powered hub, then connect your Raspberry Pi. I don't know if the wire connected to 3v3 pin touched another pin or the ground but when I add the power supply and the red light is on I can power a LED with the 5v pin but not with the 3v3 one. Anyways, now the RED power LED is constantly glowing. It was running fine for the last month on both retropie and the modbros image (using it as a hardware monitor for my pc) the only thing that has changed was i was using a power supply from amazon then today i plugged in the official ras pi 4 power supply.

I have tried following the guides provided, but For some reason I had the impression the red power light on a Raspberry Pi board was hardwired to indicate +5V input power, and goes off only if the input voltage drops below about 4. There is no video output. We are supposed to get a flashing green light, but still just a solid red light. If this was just a power issue, I can't see how the red light would be off and the green light still going. Now I'm wondering if that is true. With both the options, I get a constant red light after a couple of seconds of connecting the Pi to the power source.
