Actually did a little more checking on the service manual and found it. Icluded below, direct from the service manual. Maybe someone can include it in the proper section?

Entering the Service mode
1. Enter the service mode (S-Mode) by pressing the VOLUME
DOWN key on the instrument until the volume
decreases to minimum.
2. Press the INFO key on the remote handset while holding
the VOLUME DOWN key on the instrument.
3. Press the PROGRAM UP/DOWN buttons to select the
different adjustments under the first menu and press the
VOLUME UP/DOWN buttons to adjust the setting
(value).
5. Press the OK button to toggle into the Main Menu selection
mode and select the different Main menu sections
using the PROGRAM UP/DOWN buttons. Press the
OK button again to toggle back into the value adjustment
mode.
6. Menus up to menu 19 can be selected directly using the
remote control by pressing digital buttons 1~9, 0, notebook,
CAP, Display, Sleep, Calendar, System/INS,
Favourite, Return and Picture.
7. Press the Sound button to save the new settings and exit
the service mode.

Note: Many factory alignments appear in the menus but
only the ones listed here can be changed. The values
can be accessed and the value (hex number) on the
screen can be changed but the actual value the
instrument is using cannot be changed except at the
factory using special equipment.
The following is a list of all the menus and a
description of the individual adjustments under
each Main menu that can be changed. Only the
following menu items can actually be adjusted.

Hello Gregg,
Got into the menu using Menu 2457. I can select parameters and adjust values however, I am currently in GGL, GRL, and GBL and I cannot adjust the values. I have also noticed that there is more than one GGL, more than one GRH, GBH, of which all of these parameters have a setting of 0 and cannot be adjusted. Any ideas?

Hello Gregg,
I am calibrating a Mitsubishi WD-57731.
In reading prior posts, I do not see whether or not the power is on or off when the menu button is pressed on the remote. I also do not see any mention of a model ending in XXX31. Do you happen to have any updated info?
