Re: A couple of new Pi3B+ Not booting - 3V3 not working. Looking for further information/support.

I've been having similar issues, although I don't have a multimetre on hand to check the GPIO. Flashes the ACT light once, then just sits with the red light on. Mind you, mine worked initially, but the next day wouldn't function with HDMI in. Boots fine without it. https://www.raspberrypi.org/forums...

Re: R-Pi 3 B+ will not boot with HDMI in

The test I mentioned earlier used the same SD card. The SD card reader I have should be full compliant with standards, I've never had issues with it before. So, yes, the SD card works in my other Raspberry Pi.

Re: R-Pi 3 B+ will not boot with HDMI in

You know what, screw it. I'll just use it for something else and buy a new one. Guessing I must've managed to expose it to some static electricity, which has in turn shorted the HDMI connector to ground.

Re: R-Pi 3 B+ will not boot with HDMI in

So, my R-Pi 2B+ boots just fine with the same PSU, power-supply and display. Definitely something wrong with the Pi 3. How do I go about getting it replaced?

Re: R-Pi 3 B+ will not boot with HDMI in

Right, still won't boot up even with official PSU. The reader I'm using is a front-panel reader/writer attached to a desktop.

Re: R-Pi 3 B+ will not boot with HDMI in

It boots without the HDMI in, although it seems to be picking up something, whether that's just what it defaults to some output mode. There's a possibility it is a power problem. As for the uSDHC card reader, I'm using the built-in one. I wasn't aware you could even use an external one during bootup

Re: R-Pi 3 B+ will not boot with HDMI in

Except it booted without issue two days ago, with the same charger. It has already run without issue with HDMI plugged in, but it now refuses to boot. Certainly, it's unlikely any of mine are specced correctly, but my Raspberry Pi has booted on considerably less before it stopped doing so. The Raspb...

Re: R-Pi 3 B+ will not boot with HDMI in

In addition, the display is picked up, with

Code: Select all

tvservice -n
returning the correct information, and the EDID dump seeming sane, but no picture comes out regardless of what I do.

Re: R-Pi 3 B+ will not boot with HDMI in

1. Yes, I did. Admittedly it's not best practice, but I can't see it causing anything outside of corruption of the SD card. It is also my only option for restarting if it has not actually booted 2. I'm using DD on Linux, with the following syntax sudo dd if=image_file of=/dev/sdh bs=1M 3. Running tv...

Re: R-Pi 3 B+ will not boot with HDMI in

I understand this, but the confusing part is that the day before, using the exact same power supply (5V, 2.1A) it booted without issue, while plugged in. I've already looked into this line of reasoning, and have had little success.This was with every cable the exact same, same screen, entire setup t...

R-Pi 3 B+ will not boot with HDMI in

First, I should clarify that it was fine yesterday, and while I did not start it up connected to the same screen as it was previously, I have since, and have been unable to get it to work on either of my HDMI computer screen. Details: - If plugged-in with HDMI (regardless of power-supply), the red L...
