Symptom: (****) Several different versions of C-board and A-board were used in production, and compatibility between the C-board and A-board does not exist in certain combinations of the 2 boards. Connecting 2 boards which are not compatible may cause damage to the boards! When replacing either the A-board or C-board it is important to examine the boards to make sure that they are compatible. In most cases, an incompatible combination can be made compatible by rearranging a few components on the C-board. Solution: First, identify the types of boards according to the following descriptions. Then, make sure that the boards are compatible as shown in the table. A-board, type 1: CN503 is a 4-pin connector. A-board, type 2: CN503 is a 5-pin connector. C-board, type 1: CN1764 is a 4-pin connector, the silkscreen number on the board is 1-659-751-31, and there are no mounting locations or labels for JW1701, JW1702, and JW1703. C-board, type 2: CN1764 is a 4-pin connector, the silkscreen number on the board is 1-659-751-41, has mounting locations and labels for JW1701, JW1702, and JW1703, but only JW1701 and JW1703 are mounted. C-board, type 3: CN1764 is a 5-pin connector, the silkscreen number on the board is the same as that on the type 2 C-board (1-659-751-41), has mounting locations and labels for JW1701, JW1702, and JW1703, but only JW1702 is mounted. Notes: A type 2 C-board can be converted to a type 3 C-board by changing CN1764 from 4-pin to 5-pin, removing JW1701 and JW1703, and adding JW1702. A type 3 C-board can be converted to a type 2 C-board by changing CN1764 from 5-pin to 4 pin, removing JW1702, and adding JW1701 and JW1703 (use 5mm jumper wire). Cont. Reference: MLS8980459; A.

Park Ridge, New Jersey 07656 TV Products CSV-1 Model: GEN-TVP No. 365 Subject: Preventing ESD Damage To Circuit Boards Date: July 7, 1998 During Handling or Shipping. Symptom: (****) Improper handling and/or shipping of mounted circuit boards (MCBs) can result in electrostatic discharge (ESD) damage to new boards. ESD can also cause additional component failures on defective boards, which are being removed from a product for servicing, making troubleshooting and repair of the boards more difficult or uneconomical. Seasonal dry-air conditions and carpeted rooms of customers’ homes contribute heavily to the build up of high static voltages, and therefore extra precautions must be taken to ensure that these voltages are safely discharged prior to coming into contact with the boards. Solution: Prevent damage to the original boards as well as new boards as follows: 1-With the product power turned off, touch the metal chassis of the product to discharge any static voltage which has built up on your body prior to contacting the boards within the product. 2- As static charges may continue to be built up while servicing the product, repeat step # 1 frequently during the repair. 3- Do not remove new boards from their protective packaging until just prior to installing them in the product. 4- Prior to transporting or shipping any boards, which are removed from the product, place them in the protective packaging from which the new boards were removed.

Date: February 10, 1999 Dealers and sales personnel have recently advised us that the new Videoscope XBR models (KP-53XBR200 and KP-61XBR200) may exhibit a partially sandy or grainy picture. This occurs when the signal is sourced through component, S-video, or composite inputs and appears to happen most often with digital satellite systems, where the signals tend to be highly compressed. Generally, poor signal quality is responsible for grainy picture characteristics on most TVs. On these 2 models the symptom is most apparent when the Vivid mode is used, as this mode enhances the deficiencies of a poor signal. Use the service mode to change the settings of 2 data registers as follows: 1- Make sure the TV is OFF, then enter service mode by pressing the following keys on the remote commander in sequence: DISPLAY > 5 > VOL + > TV POWER. 2- Press the “2” button until the selected category is 3DCM 5. 3- Press the “1” button until the selected adjustment item is YNRL. 4- Press the “6” button to change the data from “1” to “0”. 5- Press the MUTE button (the word WRITE appears). 6- Press the ENTER button (the word WRITE turns red in color). 7- Press the “1” button until the selected adjustment item is CNRL (the category should still be 3DCM 5). 8- Press the “6” button to change the data from “1” to “0”. 9- Press the MUTE button (the word WRITE appears). 10- Press the ENTER button (the word WRITE turns red in color). 11- Turn off the set’s power. Re-enter the service mode and confirm that the new data you entered has been accepted. Finally, return the set to normal mode by turning off the power, followed by turning the power on again. 12- Inform the customer that the best picture quality for the typical household will be obtained when using the Standard, Movie, Game, or PRO modes. ************************************************************************ Sony Service Company Service Bulletin National Technical Services A Division of Sony Electronics Inc.

Before doing so, please check the serial number of the set. ONLY early production units require a new improved Yoke to be installed. Parts: This procedure may require the following items, Rotatable Magnets P/N 1-452-094-00 Permalloy Strips P/N 4-062-047-01, Core Alignment tool P/N 7-700-733-01 Model: KV: Ser.# Range Description Part # 36FV1 1 – 9017656 Defl. Yoke 8-451-506-11 36XBR200 1 – 9017263 Defl. Yoke 8-451-506-11 Distinguishing the New Yoke: The new yoke contains 4 bar magnets added to the outside of the housing (white arrows). Electrical changes were also made to the windings. (Fig. 1 below) Fig. 1 Important Note: Many experienced technicians have reported difficulty in obtaining good geometry with proper purity. Please read and perform all the steps in this procedure. The tilting and positioning of the yoke is critical to this procedure. Sony recommends the use of a large stand mirror for the geometric and purity adjustments. Adjustments are made to equalize the distortion (make even top to bottom or left to right). Don’t try to correct only one position on the screen, therefore it is necessary to perform the entire adjustment procedure to obtain the best results. Reference: Tom Ho PRINTED IN USA Procedure for readjusting the Yoke 1. Set customer menu Tilt Correction adjustment to zero Use the remote to enter the menu and select the toolbox icon, then select tilt and set this to 0. 2. To be performed only if the yoke is the old type. First, mark the Neck Assembly position before removing. Remove the old yoke and all the rubber wedges. Also, remove the THL plate (Fig. 11, right side picture) from the original yoke, since this does not come with the new yoke. 3. Mount the new yoke and the Neck Assembly (at the previously marked place). If the neck assembly was not marked before it was removed, then position as illustrated below. The back of the metal clamp is positioned over the spot indicated by the dashed line. 4. Purity Adjustments If the set is being adjusted in the shop, it is extremely important to face the CRT towards either the East or West direction, which reduces the influence of the earth’s magnetic field. Later you will be asked to check adjust it in a North to South position. This only reduces the possibility of readjustment upon delivery to the customer’s home. however, due to the large flat CRT, some readjustment in the customers home is likely. If the set is adjusted in the customer’s home, please face the set in the direction that the customer will watch it. This will optimize the adjustment. Note: For optimum adjustment, the set should be on for 20 minutes. 5. Remove all purity magnets, permalloy strips and rubber wedges (DY spacers). 6. Do not use an external degausser to degauss the CRT. Turn the set off and on to use the TV’s own degausser circuit. Please note proper degausser operation: If the set is on for several minutes the degausser (relay activated) will have had time for the thermistor to cool so that it will degauss properly. However if the set was just turned on for a short while and then turned on and off, the degausser may not work properly. In this case, turn the set off and wait 3 to 4 minutes for the thermistor to cool and then turn the set back on. 7. Make sure the Purity ring tabs are at the zero position. See Fig 2. 8. Loosen the deflection Yoke mounting screw, using a non-magnetized screwdriver.( a standard screwdriver, one that does not have a magnetized head able to pickup screws). 9. Input a green flat field pattern. 10. Move the deflection yoke backward, and adjust with the purity tabs so that the green is in the center and red and blue are even on both sides. See Fig. 3 for tab location. 11. Move the entire deflection yoke forward, and adjust so that the entire screen becomes green. 12. Switch the raster signal to Red and Blue and confirm the purity condition. Readjust yoke and rings as required. 13. Lightly tighten the yoke holding screw with a non-magnetized screwdriver, so that it does not move back and forth. 14. Input a crosshatch pattern. Adjust the neck assembly rings (See Fig 4 ), so the top and bottom vertical pincushion is minimized. The purity may be affected by this adjustment. Therefore, a touch up of the Purity Rings may be required. 15. If after readjusting purity there is slight impurity in the picture, place a disc magnet, P/N 1-452-094-00, on the CRT bell to correct for the mislanding. Standard purity magnets are not effective, use only this type. 16. If adjusted in the shop, face the set North to South, turn unit on and off to degauss, and confirm the purity is correct. If not, readjust. Location of Ring Magnets (on Yoke) Neck assembly magnets (on WA board- behind yoke) Fig. 3 Fig. 4 Adjusting for best geometric picture. Input a crosshatch pattern. In the service mode turn off the Blue and Red guns. To enter the service mode, start with the set off and then press the following buttons on the remote in this order in quick succession: Display, 5, Volume Up, Power. Set will then come on in the service mode. The RON & BON are approximately 40 registers after the last ID code. Once selected by using the "1" (up) and "4" (down) buttons, press the "6" button to turn off. Green pattern is only displayed. 1. Hold the yoke and tilt it up, down, or sideways to obtain the best over all geometric pattern. The yoke can be held by the rotation coil that surrounds the yoke, when positioning it while viewing the effect on the screen. When the best position is obtained, place 4 rubber wedges (spacers), part number 4-053-005-01, between the yoke and CRT to maintain the yoke position. Check that the Horizontal lines are still as straight as possible. This is one of the most important adjustments to improve Shoulder Roll off. (Fig. 5) 2. Using the Core Alignment tool (Fig. 6) P/N 7-700-733-01. Adjust the XCV core (Fig.7) to obtain the straightest lines on the X-axis. (Vertical lines bend in on either the top or bottom as this coil is adjusted) Use the crosshatch pattern. ide Vi Core Alignment tool (Fig.6) XCV core to adj X-axis (Fig. 7) 3.

Go to the RON (press 3) & BON (press 3) Before adjusting set the brightness control to minimum and the Picture control to the mid- position. Use either the crosshatch or dot pattern from the generator Center the H. Stat control. The H Stat control should not be positioned to either side, but should be somewhat centered. (Plastic knob on side of C-Board, RV:1761). The following order is recommended for adjustment: e V-Stat , BMC and then H-Stat. 1. Adj. the V. Stat rings by opening or closing the tabs to converge red, green, and blue bars in the center of the screen. (See Fig. 8) The H Stat control should be adjusted to fine-tune the convergence and should never be set to either side. (Diagrams below illustrate beam dot movement during ring adjustment) 2. The BMC (Blue Mis-Convergence) magnet rings will also interact with the V Stat magnet. Therefore you will need to go back and forth with these two magnets to achieve the best vertical and horizontal center convergence. All three magnets along with the H Stat control on the C Board should be touched up as you do the convergence alignment. Fig. 10 3. Once the adjustments are completed the V Stat and BMC adjustment rings should be locked into place with an acrylic latex paint, especially if the unit is being transported. Location Of the various adjustment on the Yoke 1. Turn off the Green gun from the Service mode (select GON, press 6). Adjust the YCH so that the Blue along the vertical center line (Top to Bottom lines) has the least amount of blue showing. If the blue can not be eliminated then the best compromise between the top and bottom of the screen. 2. Adjust the TLV so that the blue horizontal lines (Lines across the screen) on the top and bottom have the least amount of blue lines between a & b. 3. THL Plate Adjust: Note: This plate does not come with the new yoke. It must be removed from the original. Slide the THL plate into the slot on either side of the deflection yoke assembly in order to improve the horizontal convergence at the right and left sides of the screen. The plate can be mounted on either side of the yoke housing. Select the side that gives the best results. The plate should be secured with locking paint after the adjustment. (See Fig 11) 4. Corner Convergence should be corrected by use of Permalloy Strips around the Yoke. Part number 4-062-047-01. 5. Turn green back ON by selecting GON in the service mode and pressing "3" on the remote. 6. Write this data by pressing "muting" then "enter". 7. Exit Service mode by turning the set OFF and then back ON. 8. Return Brightness and Picture control to their previous settings. 9. This completes the adjustment procedure. Please verify proper geometry and convergence. ************************************************************************
