Need Help w/ JVC service menu codes...



My JVC service menu of my AV-32P903 32" JVC HDTV 4:3 has geaometry problems. When I go into service menu (sleep timer =0, HOLDING Video Status & Display simul.) I see a menu that says #1 Picture and Sound. So then... I press #1 on the remote to proceed only to see the following...

A01 to A16
S01 to S60
D01 to D20
F01 to F65

These codes are just the Picture and Sound. That is a total of 161 settings for adjusting the picture and sound. Which is cool! But... 1 problem, actually 161 problems...

What does each number adjust?
Is there a listing of what each value does?

Can someone help me get started. I would like to fix these geometry issues. Thank you ;-)
