Hi @amyautopsy ,
You may have to play detective to find out what is happening.
With the tablet resting on a table and turned on, ''gently'' start tapping in various places around the tablet (preferably not the screen), with the end of a pencil to check if you can make the tablet turn off and on etc.
Hopefully once you have isolated it to a particular area of the tablet you can use the ifixit [[Topic:Vtech InnoTab 3S]] guides to open the tablet and then check what is in the area where the problem is located.
When you have it open and you are not sure of what the problem may be post some pictures back here and someone will no doubt help you. Here's how [guide|21499]
