For your and others information, the PCB LED is located to the upper right of the logo. I’ve attached a photo. When you turn on the Game Frame, it should go full bright and then begin to dimly flash or pulse depending on whether it can read from the microSD.
Can you confirm that it’s not turning on at all? If so, it sounds like your PCB has died. Send me an email (jeremy at this domain) and we’ll get it sorted.
