Make sure your head phones are pushed in to the audio jack all the way. Touch one of the 12 gold contacts on the top of the Touch Board.
Make sure there is a micro SD card in the micro SD card reader. If there is, remove the SD card by gently pushing it inward and it should spring out. Gently wipe the gold contacts with a dry tissue before replacing it. Taking it in and out a few more times can often help remove any production residue from the contacts.
