toshiba 50H71 touch focus button

Hi I am new to the site.  I am having convergence issues with my Toshiba 50H71 tv. I am using the Service Menu to make adjustments.  When I finish, the tv prompts me with the following message: Press Touch Focus Problem: this model of TV does not have such a button on either the TV or the remote control. Is there an alternative/equivalent way of pressing the button? Thanks for any help.
