Quasar Television Access Code reset, help

I'm have no idea what my access code for my Quasar TV is and need to know how to reset the TV back to no access code.  I've been told that there is a way if you open the set and do something inside to reset the code to 0.  Can anyone help with a walk through to reset the access code??  Thanks.  Quasar 27 inch model #SP2723B
