Raspberry Pi 3 red light after installing heat sink, not booting!

Sat Aug 17, 2019 2:45 am

So I've been happily using my raspberry pi 3 for a few weeks now. I then decided that I wanted to install the heat sinks that came with my Pi. I correctly installed the heat sinks but when I plug the Raspberry Pi in, the LED only glows red.

What's wrong: The LED indicators on my Raspberry glow red when I set it up and my Raspberry Pi 3 isn't booting up.

What's expected: Both LED lights turn on and the Pi boots.

What I tried: Initially I thought it was my OS that is on a Micro SD, so I tested my theory by flashing the OS to a USB and placing the USB in the Pi afterwards. The Pi still lights up red after this. This leads me to thinking that it is an issue with the Pi itself.

Didja put in the heat sinks correctly you might ask? I did. Heat sinks shouldn't be too much of an issue with putting in unless you have Parkinson.

What should I do?

This test may not be meaningful.

Have you been able to successfully boot this Raspberry Pi reliably with this particular USB device in the past? If so, did you remember to remove the SD card?

A better test would be to write a new Raspbian image to a fresh known good SD card and try booting with it.

Which model of Pi 3 are you using? A Pi3B has to have an OTP bit set to boot from a USB device. A Pi3B+ doesn't.

In either case, do what RonR said. Try it with a new SD card with the OS on it.

And yet, here you are with a non-booting Pi, immediately after installing heatsinks. ¯\_(ツ)_/¯

Which model Pi (3B, 3B+ or 3A+)?

What are you using for a power supply?

What kind of heatsinks did you install, and how did you install them?

Is your Pi in a case? If yes, then:
  • What kind of case?
  • Did you remove the SD card before removing the Pi from the case?
My mind is like a browser. 27 tabs are open, 9 aren't responding,
lots of pop-ups...and where is that annoying music coming from?

lets see how you installed the heat-sink
an image is required for us to understand your predicament.

no image? guessing on our side is not an option.....
come back when you can share to us some images of your setup
"Don't come to me with 'issues' for I don't know how to deal with those
Come to me with 'problems' and I'll help you find solutions"

Whether installed correctly or not it does seem the most obvious correlation with the Pi no longer booting is having installed the heatsinks.

It might just be coincidence but perhaps the heatsinks are not installed as correctly as you believe they are or some misfortune occurred while installing them. It is impossible for me to say as I wasn't there, I don't know how they are installed, how they were installed, and can't see your hardware.

Hello. Sorry for my very late reply.

My raspberry pi is a 3 Model B.

I suspect this problem may be caused by a corrupted SD card but it worked in the past even while corrupted. At the current state of the sd, it is beyond saving so I am planning on getting a new one. I have tried everything to get it working right again but nothing works.

I was using a phone charger as a temporary power supply.
The heatsinks came with the pi.
I did place the raspberry pi in a case.
The case came with the pi itself.
I did not remove the SD card before removing the pi from the case.

With some cases, that is an easy way to mechanically damage the micro-SD card.

This could've been how the SD card got damaged but I see no physical damage on the card itself.

Did you use thermal paste on the heat sink, or did it use (thermal) tape?
