This information is passed along for your education only. I do not promise that it will work for your set. I will not be responsible for any damage you do to your set.
Without proper documentation and training, you can probably do a swell job of messing up your set, perhaps even damaging it. So, let me caution you before proceeding:
"Kids, don't try this at home kids without permission from the adult who paid for the set."
For complete details, you need a service manual, available for under $10 from an authorized Sony service dealer. The KV-32XBR10 and KV-32XBR70 manual was $9.00. To properly use most of the capabilities of service mode, you need some test equipment. The laser video disc "A Video Standard" (Reference Recordings LD-101) is a minimum.
Some of these adjustments require more extensive equipment, and must be performed in a particular order. The only ones I have changed on my set are the H and V POS/SIZE. Virtually all TVs overscan (throw away picture), and the XBRs are no exception. As the set ages, these may require re-adjustment.
The NTSC resolution charts on LD-101 don't appear to be properly centered. I suggest using the (outer) safe-action lines on the color-bar frame of a Criterion Collection CAV disc instead. Confirm the results with the daytime broadcast of CNN Headline News. Did you know that there is a "15 Minute Delay" disclaimer below the second line of scrolling stock quotes?
If you own a Sony XBR TV or monitor, and there is a small hole on the back panel, with a tiny push-button switch within, then your set has a remote service mode.
If you press and hold the button, then turn on the set, it will come up in service mode, with an extra line of information on the top line of the on-screen display. To exit service mode, turn off the set.

Okay, for all you Sony XBR owners who need a pick-me-up, here are the secret (as in service manual) steps for adjusting everything your set can adjust! These instructions apply to the Sony KV-27XBR10/27XBR60 models, which use the Remote Commander (TM) model RM-762. I'm not going to describe the methods for all the adjustments. I suggest that you obtain a copy of the service manual if you want more information.
Once you make the adjustments, the set will retain them until you unplug it (at which time it reverts to its EPROM settings) UNLESS you write your changes to the EPROM. Once you do that, the changes become the default (until changed and saved to the EPROM again). I strongly suggest that before you adjust anything, you step through all the parameters and write down their current settings, so that you can undo any changes you make if you need to.
Locate the service switch, which is on the rear of the set, just below the "VIDEO n IN" connectors. It is a recessed switch which I use half a Q-Tip (TM) to depress. Turn on the set while depressing the service switch. The word "SERVICE" will appear in the upper left corner of the screen, superimposed over the video image. The parameter label is displayed in the upper middle of the the video image. The current parameter value (a hexadecimal number) is displayed in the upper right corner of the screen.
While in service mode, you can still change channels using the UP and DOWN buttons (but not the numeric keypad) and sources, by pressing the corresponding "VIDEO n" button.
Turn the set off. When it is next turned on, it will be in TV mode. Any adjustments made will be in effect.
This will clear any adjustments made that were not saved to EPROM. Unplug the set. When it is next plugged in and turned on, it will revert to its saved EPROM defaults.
You can't. That is why you should write down all the defaults as they are now.
The Remote Commander is used to adjust the set. The buttons used are:
1 item up
4 item down
3 data up
6 data down
MTS
MUTING prepare to store changes to EPROM
ENTER store changes to EPROM (must be preceeded by MUTE).

Before entering service mode, (i.e. with the TV on normally), press the VIDEO button and then the RESET button to reset all user VIDEO settings to their defaults. Then do the same for the user AUDIO settings. This will insure that the picture you are adjusting is not influenced by any of the user settings.
You must be in service mode to make any adjustments
The manual has a diagram to illustrate the effect of each of the "pin" parameters. The diagrams show how vertical lines are effected by the buttons.
)|( -> ||| <- (|)
]}|{[ -> |||| <- [{|}]
/|\ -> ||| <- \|/
Are you certain that you want to save the adjustments? If you only want to use them temporarily, simply leave service mode now. Your adjustments will remain in effect until the set is unplugged.
Writing to the EPROM will allow changes to survive unplugging the set. Hold the piece of paper upon which you wrote down the old EPROM settings in one hand. (If you haven't written down the original settings, you can still return to the old settings at this point by turning the set off and pulling the plug.) With the other hand, press the MUTING button once. The word "WRITE" appears on the screen in red. This is your last chance to back out. Press the ENTER button once. The color of the word "WRITE" changes to yellow. Your changes have now been saved to EPROM. --------------------------------------------------------------------

Here are some generic instructions on how to get to the adjustments, and a listing of the adjustments that may be made.
These apply to North American (NTSC 3.58) TV's only, to the best of my knowledge.
I strongly recommend that you get the SAMS or Sony service manual for your TV before you change any settings.
As you modify settings, record the factory preset values so that you may return to them if something goes wrong. Also, record your new values, in case they aren`t saved properly. Nominal values are listed below for most settings below. And, please, please, please, don't mess with the ID-x settings! These are different for every chassis, so the nominal values below won't probably be valid!
Look at the jack panel on the back of the set; is there a service switch? This is a small, round opening in the cabinet near the video 1/video 2 inputs or the antenna jack.
If so (typically on early-90's TV's), push a plastic pen cap or similar device into the opening while turning the power on. The TV should now be in service mode.
If there is no service switch (typically on more recent TV's) type the following sequence on the remote (within one second of each other):
[DISPLAY] [5] [VOL +] [POWER]
If that doesn't work, turn the TV off and try:
[DISPLAY] [5] [POWER]
The TV should turn on in service mode.
Press 3 and 6 to make the adjustment.
Press [MUTING] [ENTER] (on the remote) after every adjustment you wish to keep!
Here is the list of settings.
(*) denotes set-up adjustments - return them to their nominal values after alignment.
