raspberry pi 4 not working?

Question

Raspberry Pi

Good afternoon. I ask for help in solving the problem with PI4. Worked in the morning and not in the afternoon. In general, the situation is such that when I supply power, the red LED is on and that's it. Without a flash drive, the LED is also on and that's it. I tried to write down the recovery EEPROM bootloader rescue image but the effect is zero. The green light does not blink. I tried another flash drive and 32 GB and 128 GB. In another raspbery from a flash drive is loaded, but not here. I take power from the charger, I also tried to change the power. The memory card connector is not bent contacts are normal. Raspbury consider new a month ago bought. I don’t know what to do anymore ....
(I checked the power supply, the flash drive is working, the image is working)

Answer 1

Connect to the console (you need a usb-uart adapter) and see what happens there.
