I purchased this board two months ago and recently acquired an SD card along with an SD card reader.
I expected the setup process to go smoothly, but unfortunately, it did not. The board shows a solid green LED and a blinking orange LED on the Ethernet port.
However, there is no power to USB peripherals (keyboard or mouse), and no video output over HDMI.
I have already tried the following troubleshooting steps:
- Replaced the USB-C cable and power supply unit (PSU) — no change.
- Flashed multiple images to a 32GB microSD card using Balena Etcher on Windows 10:

In every case, there is no boot activity, no change in LED color or intensity — only the solid green LED remains.
Is it possible that my board is defective?
If not, what further troubleshooting steps would you recommend?
Thank you in advance for your assistance!
Best regards,
Eric
