Raspberry Pi Desktop: Raspberry pi 4 Not Booting Solid Red One Green Flash

Tue, 01 Oct 2024 14:22:08 -0700

Hello I have a raspberry pi 4 and after it was lying for some time in a drawer I decided to use it for something and it doesn't work. I'm sure it used to work before and even though it was just lying in a drawer it just stopped working. When I plug it in the red led is solid and green led blinks for maybe half a second. I tried multiple SD cards (known good ones) and multiple power supplies (also connected it to laboratory power supply to make just to make sure but the same problem, also it's constantly drawin like 300ma).

There is no display over HDMI with or without the SD card. Also pi is acting the same no matter if the card is plugged in or not (same as described before red light one short green blink when connecting power). All voltages seem to be present but there is no power on the USB ports even though there is 5v at GPIO, the SD card and the ethernet seem to be getting powered as well. SD card slot is in good shape as well.

Thanks for help

Raspberry Pi B plus: Network (Wired and wireless ) sectors and usb without electricity

Sun, 11 Oct 2020 09:29:01 -0700

My model is raspberry pi b.

When I connect the device to the power, it starts to boot without problems, but there is a flashing yellow mark on the corner of the image.

But the usb section and the network segment do not work.

I replaced the power adapter and cable, but the problem still failed.

There is a part called polyfuse that I tested, which seemed to be healthy.

Raspberry Pi Desktop: Pi3 B+ struck by lightning

Thu, 20 Oct 2022 01:27:29 -0700

Hello, in Summer a lighting stuck my pi and burned it together with its power adaptor and my tv. The tv service responded that the overload came though the HDMI port.

So, here are some pictures of the pi:

and the power adapter

I wanted to know if there is a change to replace the burned component and give it life again... Or should I considered a dead pi?

Thank you in advanced.

Raspberry Pi 5: Power supply burnt out

Thu, 25 Sep 2025 09:35:42 -0700

My raspberry pi 5 burned out.I suspect the chip behind the TYPE-C burned out. I tried using GPIO for power supply and it booted up normally. I wonder if there is any way to repair it.

And I found a capacitor or resistor short circuit,anyone know its value?thanks

Raspberry Pi 3 Model B: Raspberry Pi 3B+: HDMI not working

Mon, 29 Jan 2024 08:52:07 -0700

Hi iFixers. I have a couple of Raspberry Pi 3B+ boards that are fully functional but don't detect and therefore don't show any picture over HDMI. It's not a software bug and the connector is fine. I'd appreciate any hints on what chip controls HDMI output on those boards - maybe I'd be able to replace it

After spending some time examining things around on the board I believe the fault might be due to the IC pictured below or the components to the right. Does anyone know what those are? Any hints would be greatly appreciated 🙌🏻

And one more weird detail - on the marked pin I get around 3V on the faulty boards instead of around 1,1V on a healthy one - what might cause this? Is this still that HDMI05-CL02F3 chip?

Raspberry Pi 4: [RPi4] Burnt out component, how to diagnose and replace

Wed, 11 Sep 2024 03:48:31 -0700

My Raspberry Pi 4 8GB v1.4 stopped drawing power recently.

I would plug it in to a battery bank, the red led would briefly flash, then turn off. The battery bank would report that no power was being drawn.

I eventually got it to accept power again, but the corner of the PCB near the USB 2.0 ports became very hot, and there was the telltale smell of components burning.

I think the large smd diode(?) near the USB 2.0 ports is to blame, but I'm not sure.

Can anybody help me find out what components are broken, and how to go about replacing them.

Raspberry Pi 4: USB ports are dead

Wed, 14 Aug 2024 08:15:32 -0700

Hi guys. I have a RaspberryPi 4B 4GB (newer version) that had 9V instead of 5V put through the USB-C power input according to owner.

Surprisingly it boots and works, but ethernet and USB ports are dead. I replaced the BCM54213PE and VL805 chips I took from a donor board - ethernet works fine now, but no luck with USB.

I also replaced the crystals next to both of those chips - didn't help either.

Any ideas what else I should check?

I have my raspberry pi 4 plugged into a Anker surge protector (same thing happens without the surge protector) with this old Acer monitor that I had around, when it boots it will get to the color screen than disconnect, the monitor says no signal, raspberry pi worked on a TV but refuses to work with the monitor. I plugged an old Roku Stick into the monitor and it works. Any idea why my raspberry pi doesn't work with the monitor? Model number for the monitor is S231HL
