I have a raspberry pi 4. When connected to power supply the red light keeps glowing without blinking as expected. When i boot it, the green light flashes once very fast and then nothing happens. no boot, no display. It was working good earlier but something happened. Checked the SD card, power supply, cable etc.

One green flash and nothing after a card and power swap usually points to the board. Send it in under the free Raspberry Pi diagnostic. We test it and quote before any work. If you decline, no bench fee, just return shipping.
