I also maintain a SONY XBR Service Mode list on my HomePage.
For additional information on how to preform the 16x9 squeeze (to view anamorphic DVDs at their full resolution) see the "16x9 (Anamorphic) Vertical Squeeze" or the "Sony Wega 16x9 (Anamorphic) Vertical Squeeze" FAQs that I maintain on my web site.
A complete although somewhat outdated list of Sony XBR Service Mode items can be found at http://www.repairfaq.org/~filipg/. This information appears to be for the ~1990 version of the XBR^2 series.
Note: Provisions for convergence adjustments are not enabled on 27" or smaller Sony direct view television sets.
5.1a SUGGESTED SONY SETTINGS
SONY "XBR" SERIES
TRINITONE: NTSC STD - controls color temperature - basically how greys will appear on the monitor. The "High" and "Medium" settings make everything look too blue.
NR: OFF - filters out high-frequency noise, at a slight loss of detail. Turn it OFF and the picture quality improves. It also tends to degrade fine picture detail.
DYNAMIC PICTURE: OFF - when turned ON it whitens light areas and darkens shadow areas of the picture, creating a high contrast although less accurate picture. Leave it OFF.
COLOR CORRECTION: OFF - when turned ON it tries to correct fleshtones but has a tendency to mix up certain colors and make them look like a prosthetic beige.
PROGRAM PALETTE: MOVIE: ON - only the movie mode allows the television set to run with flat and wide video bandwidth. It also shuts OFF scanning velocity modulation (SVM), when VMLV is run down to zero it will shut OFF SVM for the other modes. Each mode (Movie, Sports, etc.) has a separate adjustment memory.
SERVICE MODE ITEMS:
AXIS 0 Cleans up the red push & oranginess in the yellows
VAPI 0 Do this for all modes
VAPG 0 Do this for all modes
NRLV 0~3 Find the value 0-3 that gives the best resolution
VMLV 0 Scanning Velocity Modulation (SVM) OFF=0/ON=1
(do this for all modes)
Y-DC 0 Improves BLACK background level retention
R-YR 15 Sets the amount of RED
R-YB 15 Sets the amount of RED
G-YR 11 Sets the amount of GREEN
G-YB 9 Sets the amount of GREEN (8 or 10 may be closer)
SHPF 3 This helps with the sharpness (S-Video)
Setting R-YR and R-YB to 15 will greatly improve color accuracy and tone down the reds. Also, when Y-DC is changed from 1 to 0, DC restoration becomes almost perfect.
Sometimes setting items G-YR to 11 and G-YB to 9 may need some more fine tuning using the SMPTE color bars w/gray reference [split bar pattern] ("Color Bar w/75% Gray" VEDVD-18/3, Frame VE-46673, AVS-14415 - NOTE: VE 46673 is mis-calibrated, use AVS-14415) See the section on Setting Tint & Color Level: Matching Gray Reference for the procedure on how to adjust these two settings.
SONY "V" SERIES
GDRV 18 Green Amp.
BDRV 14 Blue Amp.
GCUT 4 Green Cutoff
BCUT 1 Blue Cutoff
Note: The setting for AMP and CUTOFF appear to be relative and not absolute on the "V" series - thus they may not work for your particular model TV.
WEGA SERVICE MODE ITEMS:
4BCT 7 input4 (component) Blue Cutoff (BCUT -1)
4BDR 30 input4 (component) Blue Amp (BDRV +1)
4GCT 5 input4 (component) Green Cutoff (GCUT +0)
4GDR 36 input4 (component) Green Amp ((GDRV +2)

SONY "MODEL-ID" SETTINGS

ID-1 This controls video features. Allows notch filter
(NOTC) to be turned off outside of service mode.
ID-2 This sets up user interface features. Enables Spanish
language menus. Allows naming of video inputs.

5.1c SONY FRONT PROJECTORS
Someday I will have a complete web page devoted to Front Projectors, but until that day here's how to enter service mode on Sony's Front Projectors use:
[enter], [enter], [up], [down], [enter]
Be sure 'Status' is ON, if 'Status' is OFF, you won't be able to get into service mode.
The manual says to make sure the remote is hard-wired, but the IR mode has always worked fine for me.

5.2 TOSHIBA TELEVISIONS
Read the _ SERVICE MODE WARNING _ before proceeding.
Sit in front the TV, you will need to be able to access keys on the remote and the TV at the same time. Turn the TV "ON"
Turn the volume all the way down to 0.
Press and hold the TV's front panel volume down button, and then press and hold the remote's "9" button for about a second.
The service mode will appear. \
-or-
Press "MUTE" on the remote.
Press "MUTE" on the remote again, but this time continue to press "MUTE".
While still pressing down on "MUTE", press the "MENU" button on the TV front. Release the "MUTE" button. You should now have an S (for service mode) displayed in the upper right corner.
Pressing MENU again should bring up the first service option Pressing the Channel Up/Down keys brings up the different service options. Pressing the Volume Up/Down keys changes the associated HEX value.
One you have entered the service mode, you can bring up the various test screens by pressing the "TV/VIDEO" button. For example, to minimize screen non-linearities, press the channel down key until PARA appears on the screen, with the associated default value (this is the parabolic adjustment option).
Then, bring up the cross-hatch pattern by repeated pressing of the TV/VIDEO button. You can then use the volume Up/Down buttons to change the PARA settings, this should cause the grid to bow in (concave) and out (convex). Adjust until the grid is the most linear.
The numbers 1,2,3,4,5,6 jump to different items. 9 displays SELF CHECK
The number 7 displays a grid. There's a blinking cursor in the upper left corner. The numbers 2,4,6,8 move the cursor. 3 cycles the colors (RGB), 5 stops the cursor from blinking, then when you push 2,4,6,8, you are adjusting the convergence at that point for the selected color. Pushing 7 again gives you a "warped" grid for a few moments. Pushing 7 again removes the grid from the screen.
If you're attempting to adjust color or geometry errors, you'll need the Video Essentials DVD, Laser Disc or some other source of test material.
