So I just got a new raspberry pi 3 b+ earlier this week by RS Components and I got it working on the first day. A couple days I shut it down and later when I tried to turn it back on, it didn't all it shows is the red led indicating the power, not the green ACT light. I tried re-flashing my 16gb SD card with NOOBS again. What should I do? (I have tried The boot problems sticky . It is not hot and I have used the GPIO pins during the week.
UPDATE I have just decided to say it is broken. I may have over-voltaged it and if anyone knows if RS components does replacements can you tell me
