thanks for your reply,
I mean my charger has two USB A ports one is 1A the other is 2.4A. I tried both ports.
I tried a different HDMI cable and a different monitor — same result.
My main question is:
How can I tell if the board is dead?
When everything is working normally, should the green LED blink to indicate SD card activity?
Right now, both LEDs just turn on and stay on — no blinking.
Any suggestions or diagnostic tips would be really helpful.
Thanks in advance!
