Code 002 enters advanced multi-point convergence adjust mode.  Ordinarily this mode is 
entered by opening the cabinet and pressing a maintenance button.  Multi-point convergence 
adjustment of these sets is documented in usenet.  After saving changes using the procedures 
documented elsewhere, cycle the set-mounted power switch to return to operating mode.

Code 127 performs a factory reset and enters an advanced video setup.  In case you're 
thinking of experimenting with the codes, you might want to skip this one.  I don't think 
there's an undo.  Proceed at your own risk.
