RPI 3 B+ Not working. Only red light.
December 21, 2023, 12:45
I powered my RPI 3 B+ with a Fast Wall Charger, Model: Q5003-US, Input: AC 100-240V.50/50Hz.0.5A Max, Output: DC 3.6-6V=3A, 6-9V=2A, 9-12V=1.5A
I did some research and the RPI only needs 5V,2.5A... So, I think I fried it. But if that was the case, then why is the red light still working?
I re-flashed the micro-sd, nothing. I used another micro-sd, nothing. I went back the the 5V,2A head and nothing works.
you do kinda need 5a but it should still work
oh researched, I'm wrong nvm
RPI 3B+ ?
for some reason I remember it needed like 3v 5a or something, idk just ignore me
anyway, green light means disk activity so this is probs one of 3 things
Which OS?
How did you install the OS?
1. power supply 2. bad micro SD card or os 3. broken pi
I'm gonna trust you with 1. so lets test 2.
as mentioned
Yes, where did he mention which OS he installed and where did he install it?
nowhere
I tried two different OS' - Raspberry Pi OS (64-bit) full and Raspberry Pi OS (Legacy, 32-bit).
Before I powered it with the wall charger, I powered it with a 5V 2A power supply and it worked fine, just had the annoying warning for insufficient power and stuff.
The 64-bit full worked fine before I powered it with 6V 3A
I tried 2 different micro SD cards, so I don't think its that
I used Raspberry Pi Imager v1.8.3 software to flash the micro sd card
Then a fuse may have tripped. If you're lucky, you'll just have to wait. I would leave the Pi alone until tomorrow and then try again. But if it doesn't run again then, it's probably damaged. And no, the devices are not always completely dead, but it is enough if an important component has been damaged.
oh you should have said it worked with a different power supply! ðŸ˜, well obviously then the current power supply is the problem
It doesnt work with a different power supply any more, but it did before I possibly blown a fuse.
I'm thinking about using the GPIO pins to power it. Although, that might not be the brightest idea.
Depends on the device that supplies it. The official display supplies the Pi via the GPIO.
But I would let it rest until tomorrow, maybe it will settle down again.
yeah theres fuses within the pi which can heal themselves
Would putting it in a cold place make it faster or easier for it to heal itself?
im not sure, I think room temperature works just as well
So... still the same situation
with the power supply that broke it?
your gonna have to leave it to heal again if you did. we need you to use the power supply that worked
Might want to change your username 😅
Have you bought the official PSU?
I wouldn't even suggest that. it's over priced. you just have to get a decent quality power supply and it'll work just fine
I'm guessing this one isn't decent quality though
No. With a 5V 2A this time.
No...
oh ok. the broken power supply probs broke the pi
So its trashed?
Maybe give it a try.
I'll buy it, but I don't think it's going to fix anything now. I might have to just get another pi
yeah
