Raspberry pi 4 Not Booting Solid Red One Green Flash
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.
