Most SONY televisions have electronic service adjustments. This means that adjustments like picture geometry, white balance, and color presets are adjusted via on screen displays, using the remote control. For complete details, you need a service manual, available from the manufacture. Any television or monitor will require professional calibration for it to meet true NTSC standards - or see my How to Calibrate a Television FAQ for do it yourself calibration. There is also a PAL version of this document available on my HomePage. This document only supports SONY Televisions manufactured for the NTSC markets. 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. PLEASE NOTE:
ORDERING THE SERVICE MANUAL: Sony Electronics Inc. HOW TO ENTER SERVICE MODE Read the SERVICE MODE WARNING before proceeding. Service switch - small, round opening in the rear cabinet near the Video inputs or the antenna jack (typically early-90's), push and hold while turning the power on - or if there is no service switch on the rear of the TV use the remote control and press within one second (timing is very important) of each other: [PWR OFF] - [DISP], [5], [VOL+], [PWR ON] The TV will turn on in service mode and the screen will look something like this:

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 Sets vert resolution for 3-d comb filter
(do this for all modes)
VAPG 0 Sets vert resolution for 3-d comb filter
(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
DCOL 0,1 Color Temperature - Select either 0 or 1 whichever
turns off the "blue tinted" whites.
DPIX 0 Dynamic Picture
AXPL 0 Cleans up Reds/Yellows
GDRV 18 (GAMP) Green Amp. - (upper level)
BDRV 14 (BAMP) Blue Amp. - (upper level)
GCUT 4 Green Cutoff - (lower level)
BCUT 1 Blue Cutoff - (lower level)
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 (black level retention) 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] (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 in the How to Calibrate a Television FAQ for the procedure on how to adjust these two settings.

SONY "MODEL-ID" SETTINGS
These ID setting are different for every chassis - in general here's what they control:
ID-0 Controls number of active video jacks.
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.
ID-3 Enables / disables Picture-In-Picture (PIP) support.
ID-4 Enables / disables Lumisponder option.
When IC 102 is replaced, these ID values must be reset. The values varies with model and chassis version. |
