Raspberry Pi 3B+, only 10 days old, running latest Raspbian and kernel. Mainly connected to TV via HDMI.

Suddenly turns off today, and can’t be revived.

Constant red light, no green light.

Tried a different SD card with the same Pi, power supply and HDMI - same symptoms.

Tried the original SD card with a different Pi 3B with the same power supply and HDMI — no problems at all.

After searching the FAQs and guides — seems the Raspberry Pi 3B+ is toast?

  • It's a long shot, but the USB power connection might be intermittent and trigger-happy. – OyaMist Jun 22 '18 at 16:25
  • Is this on-board? I tried with an alternative power supply and no luck. – Siequnu Jun 22 '18 at 19:32

Assuming your polyfuse is in a good condition(can be tested by measuring voltage between PP7 and PP4 (gnd) this should be 5V...did you Short circuit anything? or supply more than 5V.) if it isn't then wait for sometime if it still doesn't work then there is permanent damage to the polyfuse and needs to be replaced.


Here are some ways to revive a RPi


  • Try the pin method
    sometimes the SD-card reader on the pi gets deformed over time, so applying some pressure on the SD-card with a pin or folded paper could work, also cleaning it with a brush works sometimes.
    refer to this for further explanationhow a deformed SD-card looks

  • You could try booting from an USB(assuming your USB ports are in a good shape)
    Flash a USB disk or you can just insert your SD-card into a SD-card reader
    Since you are using a RPi-3b+ you only need to write
    program_usb_boot_mode=1
    In config.txt then try booting.

    If it doesn't work(USB disk doesn't get powered) then measure the voltage between PP-2 and PP-27 or PP-7 and PP-27 ideally it should be around 5V if it isn't then you could connect PP-2 and PP-27 like this guy or you could replace C97 and U13 like done over here.

    or

    if USB does get powered but you cant boot then either
    the Device is not supported or
    the the Device takes longer than 2 second to power up or respond.

    Here are some supported USB Drives
  • Sandisk Cruzer Fit 16GB
  • Sandisk Cruzer Blade 16Gb
  • Samsung 32GB USB 3.0 drive
  • MeCo 16GB USB 3.0

    If you are not using one of these its still okay since there is a good chance that your USB is supported.

  • If all fails
    If Nothing works then probably your RPi is RIP, if it is really dead then it will not read any MSD(Mass Storage Device) give any HDMI output and have a cold Soc,some 5V GPIO sources may work, like for a fan.
    If your pi isn't cold then there is some is some CPU activity but no storage to read so in this case you should replace the SD-card slot or USB slots however its risky and might damage your pi, though it is worth a try since a working pi is better than a dead one.


Conclusion: you must remember that a RPi is a small computer the size of a credit card for $35 not some super-expensive gaming rig, if it is dead then toss into a bin or replace it. Don't waste your time tinkering with an Expensive red LED.


Hope this helps!
