If turned OFF and then ON again picture is present. Unit will play the rest of the day without any problem. Solution: If the customer should complain of the symptom above please perform the following circuit changes to the BD Board. Note 1: Some BD boards had countermeasures applied at the factory. These boards do not need to be reworked in the field. See illustrations 1 through 3 for identifying the boards that have had countermeasures applied at the factory. Carefully peel up the coper tape on the side edge of the board. Lift up the shield from the board, using the Illustration 3 Reference: SBR9912 PRINTED IN USA TV Products Service Bulletin No. 484R2 Note 2: The specific procedure depends on whether or not the original service bulletin had been performed previously. If R1709 and R1713 are both mounted on the board and are 470 ohms, the original bulletin was not performed previously. If only R1713 is mounted and is 100 ohms, and R1709 is not mounted, the original bulletin was performed previously. New BD boards received from WRPC-AS must also be checked to see if the original bulletin was performed previously. Procedure for BD boards that have not had the original bulletin performed. 1-Change R1709 and R1713 from 470 ohm to 1K ohm. 2-Remove Q1701. 3-Add a 10K resistor to the A-side of the BD board near C1741 as shown in the illustration. 4-Check the solder joints of all pins on IC1718 and touch up if necessary.

Park Ridge, New Jersey 07656 TV Products CSV-1 Model: KW-34HD1 No. 496 Subject: Test Patterns Available From Digital Date: August 11, 2000 Receiver/Decoder Box. Symptom: (****) The digital receiver/decoder box (also known as the set-back box or "SBB") included with the KW-34HD1 can be used to generate test patterns for both standard definition and high definition adjustment modes if the SBB firmware version is 1.51 or higher. The test patterns are viewable on the KW-34HD1 only; they cannot be viewed on any other model TV. Solution: Follow the procedure below to determine the SBB's firmware version and to use the test patterns for adjusting the TV. Identifying the version of firmware in the SBB: a. Enter the service mode (refer to page 36 of the service manual for instructions on using the service mode if necessary). b. Select device item "DTV". c. Select register item "AGCL". d. Set the data to "1". e. Read the SBB firmware version at the bottom of the display. The SBB firmware is displayed in white characters in the following format: "nn.nn/nnnnnn, date of firmware, time of firmware" Example: "02.20/00090 Nov 03 1999 14:23:19" The version of the firmware is the first 4 characters. In the example above the version is 02.20. Do not confuse the SBB firmware version number with the TV's firmware version which also appears on the display at the same time. The SBB firmware version appears in white characters, the TV firmware version appears in green characters. Using The Test Patterns Checking picture size, position, geometry and convergence (NTSC FULL mode) 1- Tune the TV to a DTV channel, then turn the TV off. 2- Enter the service mode and select device item "DTV" and adjustment item "AGCL". 3- Change the data of adjustment item "AGCL" from "0" to "3". This brings up the first of the built-in test patterns (color bars in 1080i full-screen mode). The rest of the patterns are as follows: Reference: PRINTED IN USA Data "4": Cross-hatch with picture size markers, 1080i full-screen mode. Data "5": Cross-hatch with stars, 1080i full-screen mode.

It may turn off within minutes of turning it on, or it may take an hour or more before it turns itself off. The set can usually be turned back on again by cycling the TV's front panel power switch. Solution: This symptom may be caused by a drift of the hold-down adjustment that was set at the factory. As this adjustment in the field requires the replacement of 3 potentiometers on the D-board and the availability of a precision high-voltage meter (0.2 Kv resolution), the recommended solution is to replace the D-board.

This information is required to ensure that your parts account will be credited for the core charge when the original board is returned. IMPORTANT! See note 2 on next page. Reference: PRINTED IN USA TV Products Service Bulletin No. 507R1 NOTE 2: Early production units used a high-voltage block between the flyback transformer and the CRT. In this case, the high-voltage block must be bypassed, and the original high-voltage leads must be removed from the high-voltage block and discarded. New boards received from WRPC-AS require a high-voltage lead that connects directly to the CRT from the flyback transformer. Some D-boards received from WRPC-AS will include the proper HV and focus leads, while other boards received will not include any leads. Therefore, if you do not have a spare HV lead (part number 1-251-715-22) and a new focus lead (part number 1-900-805-19) you must order these leads when you order the D-board. ************************************************************************ .

Symptom: (132X) Topside of the picture is distorted in 1080i/480p when connected to Star Choice satellite receiver into the projection TVs Video 5 input. This symptom will only occur in a component Y, Pb, Pr configuration. Cause: The HDD201 has non-standard sync pulses on the Y output signal during the vertical blanking time. These pulses effect the TVs video processing resulting in picture distortions. Solution: For both Y, Pb, Pr and RGB connection configurations, a separate H & V Sync connection cable must be used between the satellite receiver and the video 5 input on the TV. In order to correct this symptom, a standard type RCA audio patch cable may be used. (See photos below.)

Heater resistor value change may be required. Solution: When replacing the CRT the following changes may be necessary. 1. When replacing the CRT the original may have used a braided wire across the CRT to ground the CRT and CRT Board. The replacement CRT uses a grounding wire that connects to a ground lug. This grounding lug wire should be packed in the replacement CRT box. See picture below. Reference: CRT Group PJA PRINTED IN USA TV Products Service Bulletin No. 513R1 2. Heater resistor value change. When the CRT is replaced it is required to check the heater resistor value. This resistor value will change depending on how many newer CRTs are used. It should be checked even if you are only changing one CRT because one might have been replaced prior to your present repair. Failure to do so may cause the CRT life span to be shortened. In order to determine if the CRT heater resistor is the older value or not, check the color of the CRT plastic pin base stem. (See Fig 1) Black stem indicates an older CRT and the value of the heater resistor was not changed. White stem indicates a newer CRT and the value of the heater resistor may require a different value. 3. Procedure for replacing the heater resistor. 1. After replacing the defective CRT, check the color of the CRT plastic pin base stem of all three CRTs. (See Fig 1) 2. The value of the heater resistor, on the E or G Board depending on the model, will be determined by how many of the CRTs have a white stem base. Refer to the chart below. 3. Check the heater resistor value in the set and confirm if it is the correct value as per the chart below. If not please replace the resistor with the correct value. Replace resistors for the heater circuit with the correct value resistors specified by the number of the new heater CRTs as shown in the following chart.
