    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.

    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.

    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    A complete although somewhat outdated list of Sony XBR Service Mode items can be found at http://www.repairfaq.org/~filipg/.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)
    BCUT 10 Blue Cutoff
    BDRV 29 Blue Amp
    GCUT 10 Green Cutoff
    GDRV 34 Green Amp
    DPIX 0 Dynamic Picture
    Y-DC 0 Improves BLACK background level retention
    HOSC 11 Fixes problem with color banding on component input

    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.

    5.1b SONY MODEL NUMBERS

    Model numbers:

    KV-ddXBRss
    KV = direct view sets
    KP = projectors
    dd = size of the display
    XBR, V, S, T = model line designation.
    ss = specific model designation, which appears to be independently unique.

    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.
    5.1d SONY PLASMA MONITORS

    Turn on the power. Press [Enter], [1], [8], [2], from the remote.

    POLYTRON PROBLEM PROTEK



    TV POLYTRON juga kadang mempunyai masalah di sistem memori internalnya ( pada ic program seri STVxxxx).
    Gejalanya adalah pada saat di nyalakan ,beberapa detik mau menyala sekitar 10-15 detik.Timbul suara sebentar ,setelahnya protek/standby.
    Ini di sebabkan sedikit error pada data memory yg terdapat di dalam IC program.
    Untuk mengatasi hal seperti ini , anda cukup melakukan trik yg akan saya berikan berikut ini:
    Nyalakan pesawat TV seperti biasanya, dan tunggu posisi tv dalam keadaan protek/standby,gunakan remote orsinilnya ,tekan tombol menu pada remote dan tahan sekitar 3 - 5 detik hingga tv menyala secara otomatis.
    Biasanya Tv langsung normal kembali,karena data dalam memory telah di reset ulang secara otomatis ke keadaan PP ( pactory preset ).
    Kenapa bisa terjadi begitu? sebab kalau pada posisi TV standby.tombol power memberi sinyal perintah hidupkan ( ON ) pada IC program.Kalau pada posisi standby, tombol menu yg ditekan terus dalam sekian detik akan memberikan input RESET data memory ( flash).Dan jika kondisi memory normal,maka dalam hitungan 'timing' tertentu perintah tersebut akan di artikan sebagai sinyal masuk ke posisi MENU SERVICE.Dan sistem secara otomatis akan meminta passcode untuk masuk kedalam sub menu service.
    Kode passcode nya adalah 1013 untuk setelan dasar ( fitur) dan 1014 untuk mengatur parameter -parameter utama ( H-frek, V-amp, AGC, AFC dll)
    Dan jika anda mendapat problem seperti yg saya utarakan di atas,cara tersebut adalah yg paling mudah untuk mengatasinya.Tapi sebelumnya pastikan dahulu bahwa semua titik solder dalam mesin TV tidak bermasalah, ada baiknya anda teliti dulu semua titik solder sebelumnya.
    Karena apa? sebab sistem proteksi juga akan membaca keadaan rangkaian sebelum tegangan-tegangan normalnya akan diaktifkan.jika ada masalah di titik solder ( biasanya terdapat pada titik kaki IC vertikal ,kaki FBT, regulator) sistem akan tertahan ke posisi protek.

    PROTEKSI PADA TV FLAT SANYO SLIM



    Generasi terbaru tv sanyo berlayar CRT flat atau standard.menggunakan IC utama (MCU) seri: LA 769XX.yang secara internal mirip prossesor..dan kelebihan sekaligus kekurangan pada system rangkaian tv yg menggunakan IC ini adalah adanya sistem proteksi yang cara bekerjanya mengidentifikasi konfigurasi seluruh rangkaian berdasarkan parameter2 yang di tanam dalam ic memorinya..jika pada saat start, ada kelainan parameter tersebut (misal : besaran AGC, frekwensi horisontal,linearitas vertikal) nya berbeda ,maka secara otomatis IC ini akan memproteksi diri pada keadaan standby..dan baru akan menyala kembali kalau rangkaian sudah terkoreksi sebagaimana mestinya.
    Pada kasus TV Flat sanyo CG21XS2..pesawat ini selalu balik ke posisi standby terus bila akan dinyalakan..padahal semua tegangan ,baik B+ nya ataupun teg.Vertikal bahkan 15Vnya juga normal..tetap saja tv selau protek.
    ternyata disebabkan kondisi flyback-nya ada sedikit masalah kecil..perubahan kapasitas capasitor internal FBT..menjadikan output tegangan baik untuk heater dan ABLnya berubah,meskipun hanya sedikit sekali.
    sedikit trik bisa membantu masalah ini ,dengan cara meng-cut (memutus) jumper J830..yang menuju pin 23 dari IC LA76938 ( pin ini dinamakan: INT1/P.0) salah satu pin untuk mendeteksi / mengontrol bagian horisontal.
    spontan TV akan start seperti sediakala..jika mata anda tajam akan terlihat gambar seperti kekurangan tegangan untuk Video out/180-200V.
    jika anda mendapat kan kasus TV sanyo seperti ini ,tidak ada salahnya gunakan trik seperti ini.untuk memastikan bahwa tv tidak terproteksi .
    selamat mencoba

    REGULATOR /POWER SUPPLY SERBA GUNA




    Ada sebuah kit /modul siap pakai:REGULATOR GACUN buatan gz.jiachun china yang amat sangat serba guna dan sangat mudah di aplikasikan untuk regulator apa saja.
    Kenapa saya katakan demikian? karena pada kondisi penerapan tertentu kit ini hanya cukup memasang dua buah kabel saja.Sebuah terobosan yang sangat berguna (terimakasih GACUN).
    Regulator apapun dan bagaimana pun selama trafo converternya masih bagus,kit ini dapat bekerja dengan baik untuk menggantikan rangkaian regulator aslinya.Buang habis semua jalur rangkaian regulator asli (tentunya yg sudah rusak dan tidak dapat di repair lagi) bagian primer,dan kita hanya perlu dua titik pasang.Yaitu pin trafo yang terhubung dengan tegangan input ( VCC) biasanya 300v,dan pin yang menuju ke collector Transistor /IC regulator.
    Cara pemasangan nya adalah amat sangat mudah .Regulator gacun hanya mempunyai tiga (3) jalur kabel; merah adalah VCC input yang nantinya dipasang pada titik trafo yg menuju collector TR/IC regulator.kabel hitam adalah ground ( negative) dan kabel biru adalah untuk feedback ( pendeteksi perubahan tegangan output, kabel ini bisa dipasang atau pun boleh dibiarkan saja ( itu hebatnya).
    Biarkan /jangan di copot capasitor dan resistor yg berada dijalur VCC ke collector ( kapasitor/resistor osilasi trafo biasanya mulai 680pF-2n2F/2KV).
    Pasang kabel hitam ke ground. pasang kabel merah ke kaki trafo collector (kabel merah ini di asumsikan sebagai pengganti collector TR/IC ),dan kabel biru ke jalur optocoupler ,jika ada.
    Putar trimpot gacun pada posisi minimum ke kiri habis ( CCW ).hidupkan power supply.dan atur tegangan output regulator sebagaimana mestinya. TV biasanya 115V untuk B+ nya.5V untuk regulator DVD dll.

    Amat mudah mengaplikasikannya ,coba saja baik untuk TV14-29" , VCD/DVD atau monitor.karena modul ini sudah terbungkus sangat rapih dan terlindungi oleh casing nya yang cukup mungil.
