It's getting hard to find info on Service menu settings for Sony's WEGA CRT Tvs. Much of the this info has disappeared from the Web. For the most part, this thread is relevant for WEGA CRTs produced from around 2000 to 2006 or so.
The Following info comes from:
https://web.archive.org/web/20070525032945/http://myweb.accessus.net/~090/sonyadj.html#warn
As you can tell, this isn't on the web anymore. I had to use wayback machine to pull it up. I have slightly reformatted and cleaned up this info for the forum.

HOW TO ENTER SERVICE MODE
[PWR OFF] - [DISP], [5], [VOL+], [PWR ON]
-or-
[PWR OFF] - [DISP], [5], [PWR ON]
The TV will turn on in service mode and the screen will look something like this:
NAVIGATE IN SERVICE MODE
[1] = Moves to Previous Menu Item
[4] = Moves to Next Menu Item
[3] = Adjusts Value Up
[6] = Adjusts Value Down
[MTS] = Toggles Stereo/Mono Audio
SAVE NEW SETTING
[MUTE] followed by [ENTER] = stores NEW service mode settings to NVRAM
RESTORE USER SETTINGS
[8] followed by [ENTER] = Restores All *USER* settings to factory defaults
RESET VALUES
[0] followed by [ENTER] = Read Default service mode value from stored settings. (service mode reset)
LEAVE SERVICE MODE
[PWR OFF] = Leave Service Mode any settings not written will be in effect until TV is unplugged or a Reset is performed.
RETURN TO DEFAULT SETTINGS:
BEFORE storing NEW settings - unplug TV from wall, wait a few seconds, then plug back in, turn TV set on - All settings not written will have been lost.
AFTER storing NEW settings - restore original value from list you made of original values before adjustments and store in NVRAM.
PLEASE NOTE:
RECORD ALL ORIGINAL VALUES BEFORE
MAKING ANY ADJUSTMENTS.
XBR250 COLOR BANDING PROBLEM
If you have a XBR250 and you're experiencing horizontal blue, green or red banding across the screen with a component video connection, you will need to enter service mode and adjust the HOSC parameter. Initially HOSC is set to 7 (factory default), you'll need to change it to about 11 - this will eliminate the color banding in the picture.

NOTE:
Not all ITEMS appear on all televisions models.
Provisions for convergence adjustments are not enabled on 27" or smaller Sony direct view television sets.
Typical settings may not apply to your particular model and are shown only for reference purposes.
-----------------------------------------------------------------
One of the most important things you can do is to write down ANY changes you make in the Service Menu. Write down current and then new settings. It's very, very easy to misadjust these TV's and fuck everything up.
I will continue to update this first post as new info is found. Keep in mind not all the Service Menu options appear on all TV's.
