my Sharp Viewcam will not power up ?

my viewcam will not power up with the battery or even with the ac adapter, someone has told me to try a new battery but i was wondering if the battery makes the circuit in the camcorder and that is why it wont work, its a good camera and it would be a shame to have to throw it out, please has anyone any ideas on what this could be????
