Solution: If the customer should complain of the symptom above please do the following: Inspect for loose anode connector: The anode cap is supposed to form a vacuum with the CRT glass. It is possible that the cup is holding a good vacuum, but the metal spring connector is not properly engaged into the button slot on the CRT. You should inspect these models for a loose connection as follows: After turning off the set and properly discharging the CRT, peel up the rubber of the anode cap to determine if the metal spring connector is properly engaged into the button slot on the top of the CRT. Both the left and right side of the metal spring connector should be snapped into the button. If it is properly inserted into the button, you should turn down the anode cup so that it forms a vacuum with the CRT. If it is suspected that the anode is not making a good connection: There should be enough spring in the connector so that when gently tugging on the anode lead and with the rubber anode cup turned upward (not touching the CRT) the connector will remain in place. When gently tugging on the lead, care needs to be taken so that not too much force is used so that the metal spring connector deforms. Re-installing the connector: If the anode is loose, carefully re-insert the metal spring connector by installing one side of the connector into the button and then the other. You should then gently tug on the lead to make sure it is engaged. If the metal spring does not properly stay in the button, it may have been bent. In this case, gently remove the spring and then reshape it so that it will adequately fasten into the button once inserted. Turn down the anode cup so that it forms a vacuum with the CRT. Note: When repairing the set, it is important that no stress is placed on the anode lead, or the metal spring clip under the rubber cup may bend resulting in poor connection with the CRT.

PS8001 Mounting Location (D-board) G2 Adjustment Procedure IMPORTANT: The room must be as dark as possible when making the following adjustments. 1- Prepare the G-2 adjustment jig shown on page 5 of this bulletin. This jig requires three alligator clips, two 6.8K/3 watt resistors, and three 2.2K/3 watt resistor. Use different colors for the alligator clips to make identification easier. CAUTION! The following procedure involves handling test leads with voltages as high as 210Vdc. Appropriate care should be exercised. 2- Turn on the set and allow it to warm up for at least 15 minutes with a picture on the screen. 3- Remove the front panel. A. Remove the left and right side speaker grills. B. Remove the bolts on both sides of the front panel. C. Protect the toe rail from scratches by placing a thin sheet of cardboard or paper between the bottom of the front panel and the toe rail. D. Lift the front panel slightly, then pull it straight out and set it on the floor just in front of the toe rail. E. Unplug the three connectors from the front panel and move it out of the way. 4- Select a video input with no input signal, so that the screen is black. 5-Make sure that the remote control is in the normal TV control mode by pressing the "TV ANT" button directly above the number "3" button on the remote control. (The LED near the top right corner of the remote control lights red when buttons are pressed when it is in the normal TV control mode, and it lights green when buttons are pressed when it is in the DTV control mode). 6-Put the set into the service mode (with the TV power OFF press the following buttons in the order shown: "DISPLAY" > "5" > "VOLUME +" > "POWER"). 7- Select category “MCP1”, adjustment item “P ON”, then press the “6” button on the remote control to turn off the on-screen displays (the screen should be all black now). 8-Cover the lenses of the green and blue CRTs. 9-Attach the jig's alligator clip that is soldered to the free end of the last 6.8K resistor to the ground on the CG board. The fast-on terminal where the black ground wires connect to on the CG board is a convenient place to connect the alligator clip. 10-Attach the jig's alligator clip that is soldered to the free end of the first 2.2K resistor to the 210 volt test point on the CG board. This test point is a jumper wire labeled "JW7211" which is mounted over a small hole in the left-front corner of the CG board. 11-Attach the jig's alligator clip that is connected to the junction of the first 2.2K resistor and the second 2.2K resistor to KR TP7103 on the CR board (this is a pin that is located near the front-left corner of the board). 12-Confirm that the voltage at TP7103 is 175 - 180 Vdc. 13-Turn the red G2 control on the focus pack clockwise until you can see some red retrace lines. 14-Turn the red G2 control counterclockwise to the point where the picture is just barely cut off (the retrace lines just disappear and there is no red tint to the screen). 15-Cover the lenses of the red and blue CRTs. 16-Move the alligator clip from KR TP7103 on the CR board to the KG TP7203 on the CG board (this is a pin that is located near the front-left corner of the board). Leave the other 2 alligator clips attached to CG board. 17-Confirm that the voltage at TP7203 is 175 - 180 Vdc. 18-Turn the green G2 control on the focus pack clockwise until you can see some green retrace lines. 19-Turn the green G2 control counterclockwise to the point where the picture is just barely cut off (the retrace lines just disappear and there is no green tint to the screen). 20-Cover the lenses of the red and green CRTs. 21-Move the alligator clip from KG TP7203 on the CG board to the KB TP7303 on the CB board (this is a pin that is located near the front-left corner of the board). Leave the other 2 alligator clips attached to CG board. 22-Confirm that the voltage at TP7303 is 175 - 180 Vdc. 23-Turn the blue G2 control on the focus pack clockwise until you can see some blue retrace lines. 24-Turn the blue G2 control counterclockwise to the point where the picture is just barely cut off (the retrace lines just disappear and there is no blue tint to the screen). 25-Remove the jig's alligator clips from the boards. 26-Turn off the set’s power, then turn it on again (this cancels the service mode). 27-Select a video input or tuner that has a video signal present. 28-Verify that the black levels and white balance are correct and that the picture quality is good. The convergence may appear to be out of adjustment at this point. If so, press the autofocus button on the set to see if the convergence comes back in. Additional adjustment may not be necessary. 29-Secure the G2 adjustment controls on the focus pack with locking paint; do not to allow the paint to seep inside of the controls. 30-Re-install the front panel and speaker grills. Be sure to connect the three white connectors to the front panel before putting it back in place. This completes the G2 adjustment. G2 Adjustment Jig To TP7103 on CR board (step 11).

Solution: The 32 and 36 inch televisions range from 200 – 240 lbs. and therefore requires at least two people to handle properly. There is a tendency, for one person to place a corner of the TV on a stand (so he can remove his hands) and then to slide the set into place (See Fig. 1). When the weight of the TV is resting on a corner of the cabinet or pressure is exerted to the bottom center of the cabinet, (especially if towards the back of the set) the weight of the TV can cause the bottom of the cabinet to flex upwards, thus damaging the main circuit board. In the handling of these sets, whether during initial installation or during servicing, damage may occur if the following directions are not followed: 1. The set should be lifted from the sides of the set towards the front. The back is used to keep the set from tilting. The set then must be placed over the resting surface (stand, table, etc.) and lowered softly straight down on the flat surface. Also, please avoid placing the bottom of the set on the two front protrusions of the TV stand, during the installation process, as this will damage the board. Fig. 1 Fig. 2 Reference: FPR-U1022 PRINTED IN USA xxx Products Service Bulletin No. xxx 2. Under no circumstance should a hand truck be used to move these TVs. Due to the large size of these TVs, in many cases they must be removed from the box and are brought in via a hand-truck. The use of a hand-truck can cause upward pressure to the bottom of the chassis, thus damaging the main board. If a hand-truck must be used then to prevent damage the set should be placed on a flat board that spans the whole width of the TV. The hand-truck can be placed under the board for safe transporting. See Fig. 3 Fig. 3 3. To prevent the “A” Board from cracking please ensure the set is placed down on a flat surface completely. See Fig 2. 4. If the board can be repaired it should not contain excessive circuit board patching, no more than 5 jumpers. The board repair should not cause additional failure or safety hazard due to the repair of the board, especially in the High Voltage Horizontal Output Circuit. ************************************************************************ Sony Service Company Service Bulletin National Technical Services A Division of Sony Electronics Inc. Park Ridge, New Jersey 07656 TV Products CSV-1 Model: KWP-65HD1 No. 448 Subject: Service Mode Adjustment Procedures Not Date: December 29, 1999 Working Properly Due To Incorrect Mode Setting Of Remote Control. Symptom: (****) The set may not enter the service mode after following the remote control button sequence shown in the service manual. In other cases, the service mode can be entered, but some or all of the adjustment procedures do not appear to work as described in the manual. For example, when using the number buttons to change data, the digital TV channel changes and the new channel number appears on the screen. Solution: These problems are most likely caused by the remote control not being set to the correct mode for the adjustments. The remote control actually acts as 2 separate remote controls in one package: one for controlling the analog TV functions and one for controlling the digital TV receiver/decoder box functions (the digital TV receiver/decoder box is mounted in the bottom right rear of the set). The problem occurs when the remote control is actually in the digital TV control mode when it should be in the analog TV control mode. Identifying the current mode of the remote control. Observe the color of the LED near the top right corner of the remote control while pressing any one of the number buttons. If the LED illuminates red, the remote control is in the analog TV control mode. The analog TV control mode is the correct mode for making adjustments. If the LED illuminates green, the remote control is in the digital TV control mode. Changing the mode of the remote control. Press the button marked " TV" that is found directly below the LED. Each time this button is pressed the control mode toggles between the analog TV control mode the digital TV control mode. Making geometry and convergence adjustments. The geometry and convergence adjustments shown in the service manual must be made separately for each of the different display modes (FULL, ZOOM, WIDE ZOOM, and HD). When making the adjustments for the HD (high definition) mode, the set must be operating at high definition scan rates. Simply watching a digital TV program does not guarantee that the set is operating at high definition scan rates. The easiest way to make sure that Reference: PRINTED IN USA AUTOFLAGGED -YES TV Products Service Bulletin No. 448 the set operates at high definition scan rates while making the adjustments in the HD mode is to follow this procedure: 1- Remove the antenna cable from the digital receiver box at the bottom right corner of the back of the set. 2- Turn the set on. 3- Press the "DTV ANT" button on the remote control (it is located right above the number "2" button. 4- Make sure that "DTV" appears briefly at the top left corner of the screen and "No Program" is displayed at the bottom left corner of the screen. 5- Turn the set off. 6- Press the " TV" button ( located directly below the LED). This puts the remote control back to the analog TV control mode. Confirm that the remote is in the analog TV control mode by pressing any number button: the LED should illuminate in red (not green). 7- Enter the service mode by pressing the following buttons in the order shown: "DISPLAY" > "5" > "VOL +" > "TV" power button. At this point, the service mode should be active and the set will be operating at the high definition scan rates. Be careful not to accidentally switch from high definition mode to standard definition mode; if you do, you cannot re-enter the high definition mode unless you start over again from step 2. 8- Use the number buttons and joystick control button as shown in the service manual to make the geometry and convergence adjustments in high definition mode. 9- Be sure to press the auto-focus button on the top right side of the TV immediately after writing the final adjustment data to memory before exiting the high definition mode! This step ensures that the convergence adjustments you just made can be automatically be made by the customer in the future if the convergence should drift. 10-Don't forget to reconnect the antenna cable to the digital receiver/decoder box after the high definition adjustments are finished. The adjustments for the analog TV modes are made when the set is operating at standard-definition scan rates. Ensure that the set is operating at standard­definition scan rates by pressing the "TV ANT" button before starting the adjustments (it is located right above the number "3" button). Be sure to press the auto-focus button on the top right side of the TV immediately after writing the final adjustment data to memory before exiting each screen mode! ************************************************************************ S Sony Service Company National Technical Services Service Bulletin A Division of Sony Electronics Inc.

PLEASE NOTE: Power and GND are provided from the JIG. The RESET pin on the Microcontroller will need to be tied LOW. A test clip is provided on the connector for this purpose. There is a special note at the end of the manual for RA-3 suffix 12 & 13, RA-4 XBR models. The READ and WRITE should take only a maximum of 12 seconds. The RA-4 XBR BD Board will take approximately 10 Seconds. READ To read from the NVM chip on the original board, clip the test clip to the NVM chip and press the read key. The NVM JIG will read contents of the original memory and program the JIG memory with this information, the read (green) LED will then light up until the next key press. WRITE To write to the new board, after reading from the original board, clip the test clip to the new NVM chip and press the write key once. When the JIG has completed the write, the yellow LED will light. ERROR INDICATION If the JIG encounters a problem with communication to the NVM chip (i.e. no acknowledgement on the line that a chip is there), the power LED will blink. AFTER GETTING AN ERROR INDICATION Press one of the keys once for a duration of approximately second. This will take you out of the blinking RED LED mode and a solid RED LED will again light. At this point you are back at the starting point and may press either Write or Read buttons. POWER DOWN If the unit is powered for a period of time equal or greater than 5 minutes the JIG will power down. By turning the unit off and then back on again, you may restart your process. DIP SWITCH 1 AND 2 designated for XBR toggle. 3 AND 4 designated for pull up resistors connected with the I2C lines. SHIP TO MODE DIP (Regular NVM mode, NO pullups) RA-4 XBR BD board NVM MODE, PULLUPS REGULAR NVM MODE, PULLUPS FOR BOTH SCL AND SDA This option will be needed for A board and BM board on RA-4 XBR. As well as for NVMs on earlier models that require pullups. NOTES If you press either key the software will start the process of either writing or reading. RA-4 XBR OPTIONS With the RA4 you will need to ground the WP lines. BD Board pin 55 IC1703 PJED-CPU A Board pin 55 IC1008 Main CPU BM Board Grounding 55 IC1009 Pull ups will be needed with the RA-4 model on all boards. There are no pullups close to the NVM chip on any of the boards. On earlier models of Rear Projection you will still need to Ground the RESET line of the Microcontrollers. RA-3 suffix 12 & 13 OPTIONS With the RA3 PJED NVM you will need to ground the WP line pin 55 IC805 PJED-CPU and supply +5 from the NVM reader/writer to pin 41 and 58 IC805 PJED-CPU. With the RA3 Main CPU NVM you will need to ground the CPU crystal pin 12 IC002 Main CPU. Also it will be necessary to use the NVM reader/writer +5 supply for +5 standby pin 41 IC002 Main CPU. ************************************************************************ .
