SAFETY CHECK-OUT
After correcting the original service problem, perform the following safety checks before releasing the set to the customer: 1. Check the area of your repair for unsoldered or poorly-soldered connections. Check the entire board surface for solder splashes and bridges. 2. Check the interboard wiring to ensure that no wires are "pinched" or contact high-wattage resistors. 3. Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair. Point them out to the customer and recommend their replacement. 4. Look for parts which, though functioning, show obvious signs of deterioration. Point them out to the customer and recommend their replacement. 5. Check the line cord for cracks and abrasion. Recommend the replacement of any such line cord to the customer. 6. Check the B+ voltage to see it is at the values specified. 7. Check the antenna terminals, metal trim, "metallized" knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below.
LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500 microamperes). Leakage current can be measured by any one of three methods. 1. A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers' instructions to use these instruments. 2. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job. 3. Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The "limit" indication is 0.75V, so analog meters must have an accurate lowvoltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2V AC range are suitable. (See Fig. A)
To Exposed Metal Parts on Set

6. REPLACING OPTICAL PICK-UP
6-1. Handling
1) A red laser diode for DVD requires more attention to static electricity than general infrared laser diodes for CD. Because its durability to static electricity is far weaker than that of infrared laser diodes, always use an earth band when handling the optical pick-up block as service parts. 2) As for the flexible board KHS-180A (RP) packed as service parts, the short lands have been soldered to protect from static electricity. Accordingly, remove solders when replacing optical pick-up. (See Fig. 6)
DVD short land
3) In handling the KHS-180A (RP), do not touch inhibited parts shown in Fig. 7, but grip the slide base bearing and U-shaped guide.

Before checking, the content of address 0 is read for saving, but if it cannot be read, the error is displayed and operation is terminated, and data writing is not executed. In this diagnosis, 16-bit data is checked. 16 kinds of patterns are written by shifting 1 bit each from 0x0001 toward the left. If write/read mismatch error occurred, checking can be repeated. Even if an error occurs after write/read check started, the saved data are written when this diagnosis is quitted, but whether data are written correctly is not guaranteed. (5-3) SSI (Serial) Serial register write Register read matching check Error 05: Write/read data mismatch error 33: SSI serial transfer error 0x00 0xff data are written to the FCCR register for SSI, then they are read to check for matching. If write/read mismatch error occurred, checking can be repeated.
6-4. General Description of Checking Method
This section describes briefly a checking method of each diagnosis item, following the order of menu. The number in ( ) in each item indicates a diagnosis item number. (2) Memory (2-2) Syscon ROM (IC803) Check Checksum calculation Error: Not detected At addresses from 0x00000 to 0xfffff of Syscon ROM (IC803), checksum is calculated by adding 8-bit data, and the result is displayed with 4-digit number in hexadecimal notation. As the error is not detected, compare the displayed result with original ROM checksum. (2-3) Syscon RAM (IC802) Check (DMA used) Syscon ROM (IC803) Syscon RAM (IC802) matching check Error 05: Write/read data mismatch error External RAM (IC802) of IC805 (Syscon) is saved in the stack by 256 bytes each, and ROM data are transferred to the DMA. Then, the data are compared with ROM (IC803) data every byte. In detail check, the bit inverted data are further written, and rechecked. During checking, all interruptions are stopped. Also, variables use only the stacks including save area and bit inverted buffer. As a processing is executed in the closed circuits within this function, the data transfer to stack area also uses the DMA. In the detail check, all areas of external RAM (IC802) are checked twice by inverting the data, but in the simple check, one block is checked, then the subsequent 4 blocks are skipped, and also a check of inverted data is not executed. If write/read mismatch error occurred, checking can be repeated.

(5-4) Servo DSP Download DSP (IC506) code area ROM/RAM discrimination RAM: Program download Revision data read ROM: Revision data read Error 04: Data read error 13: DSP data not ready For the Mask ROM, no download can be executed. Download is possible for the RAM only. ROM/RAM is discriminated by the DBUSY signal of DSP (IC506) pin 4 after hardware reset. The diagnosis provides exclusive download flag. For this flag, download not executed :0 download already executed : 1 download error :2 ROM/RAM is discriminated by the status of DBUSY signal after hardware reset. If RAM, the servo control code is downloaded. If no error is found, the version No. is read from address:200, and displayed. If ROM, the version No. is read from address:200 immediately. Compare displayed data with existing data. If RAM, "DSP Download Rev.=xxxx" is displayed. If ROM, "DSP Mask ROM Rev.=xxxx" is displayed. (5-5) Servo DSP Register (Program download) Data write Read matching check Error 04: Data read error 05: Write/read data mismatch error 13: DSP data not ready 14: DSP download error The download flag is checked, and if 0, the program is downloaded. However, in the case of ROM, it is not downloaded. Unless download error occurs, the content of address 200h of DSP (IC506) is read for saving, then checking starts. In this check, 16 kinds of patterns are written to the address 200h by shifting 1 bit each from 0x0001 toward the left, then they are read. If write/read mismatch error occurred, checking can be repeated. (5-6) Servo DSP Reset Line Register write Hard reset Register read Error 02: Reset error 13: DSP data not ready 14: DSP download error In the case of RAM, this diagnosis checks that the register cannot be read after hardware reset. Unless download error occurs, the content of address 200h of DSP (IC506) is read, and after hardware reset, the data is read again for comparison. The check results in OK, if the register cannot be read, or data are not matched even if it can be read. The reset error occurs if read data are same as that before hardware reset. In the case of ROM, whether the version No. is initialized by the reset is checked. First, the version No. is read, then its complement is written. After hardware reset, the data is read again and if it matches the written data, the reset error occurs.
(6) Data Source (6-2) Register in ARP (IC806) Register write Register read matching check Error 05: Write/read data mismatch error Data from "0x00" up to "0xff" are written to 12 registers where all bits can be written and read, then read to check for matching. If write/read mismatch error occurred, checking can be repeated. (6-3) Reset Line in ARP (IC806) Register write Hard reset Register read Error 02: Reset error 05: Write/read data mismatch error After "0xfe" is written to the INTEN3 register, whether it is initialized to "0x00" by the reset pulse signal is checked. To make sure, the written data is read to check for matching before reset is executed. (6-4) DRAM (IC810) in ARP ROM data ARP (IC806) DRAM (IC810) ARP (IC806) read matching check Error 03: Data write error (ARP (IC806) is not enabled for data writing) 04: Data read error (ARP (IC806) is not enabled for data reading) 05: Write/read data mismatch error ROM (IC803) patterns are copied to all areas to be checked. Each time 256 bytes are copied, the addresses of copy source (ROM) are returned by 254 bytes. In detail check, all areas are checked to verify all bits in DRAM (IC810), then the inverted data are further checked in the same manner. The bus width of ARP (IC806) is 16 bits. This check program displays addresses in 16 bits. Overwriting by the shadow can be detected, as the data are written to all areas, then read. In the detail check, all areas of RAM (IC802) are checked twice by inverting the data, while in the simple check one block is checked, then subsequent 4 blocks are skipped, and also inverted data are not checked. If write/read mismatch error occurred, checking can be repeated. (6-5) Interrupt Line in ARP (IC806) Data transfer request Data transfer stop interruption from ARP (IC806) Error 21: ARP (IC806) interruption is not detected AC-3 audio data stored in ROM (IC803) are transferred to the ARP (IC806), then the designated sector data output stop interruption from ARP (IC806) is detected. To discriminate the Decrypt (IC811) interruption which is also sent in the same line, the Decrypt (IC811) interruption is all masked.
6-3
(6-6) Register in Decrypt IC (IC811) Register write Register read matching check Error 05: Write/read data mismatch error 0x00 0xfc data (lower 2 bits are masked) are written to the interrupt register, then read to check for matching. If write/read mismatch error occurred, checking can be repeated. (6-7) Reset of Decrypt IC (IC811) Register write Hard reset Register read Error 02: Reset error 05: Write/read data mismatch error After "0xfc" is written to the interrupt register, whether it is initialized to "0x00" by the reset pulse signal is checked. To make sure, the written data is read to check for matching before reset is executed. (6-8) Interrupt Line in Decrypt IC (IC811) ROM (IC803) ARP (IC806) Decrypt (IC811) Error 22: Decrypt (IC811) interruption is not detected AC-3 audio data stored in ROM (IC803) are transferred to the Decrypt via ARP (IC806), then the reserved data interruption from Decrypt (IC811) is detected. To discriminate the ARP (IC806) interruption which is alsosent in the same line, the ARP (IC806) interruption is allmasked. (6-9) Reserved Data Head Byte Reading ROM (IC803) ARP (IC806) Decrypt (IC811) reserved data head byte read matching check Error 05: Write/read data mismatch error 22: Decrypt interruption is not detected AC-3 audio data stored in ROM (IC803) are transferred to the Decrypt via ARP (IC806), then the reserved data head bytes are read from Decrypt (IC811) register. As this audio data consists of 5 sectors, 0, 1, 2, 3, 4 data are written at the head of reserved data of respective sectors. Whether these data are matched is checked through every sector interruption. If write/read mismatch error occurred, checking can be repeated. (7) AV Decoder (IC203) (7-2) Register in 64020 Register write Register read matching check Error 05: Write/read data mismatch error "0x00" "0xff" data are written to 51 registers where all bits can be written/read, then they are read to check for matching. If write/read mismatch error occurred, checking can be repeated.
(7-3) Reset Line in 64020 Register write Hard reset Register read matching check Error 02: Reset error 05: Write/read data mismatch error After "0xff" is written to the Capture/Compare Control Register 0, whether it is initialized to "0x00" by the reset pulse signal is checked. To make sure, the written data is read to check for matching before reset is executed. (7-4) DREQ Signal Line in 64020 AV Decoder (IC203) DMA check Error 03: Data write error 04: Data read error 05: Write/read data mismatch error 06: DMA transfer DREQ error 07: DMA transfer address error The connection of DREQ signal line to the AV Decoder (IC203) is checked through DMA transfer. If no error is found in DMA transfer, the transferred data are compared with the DRAM (IC810) data read from the register. (7-5) DRAM in 64020 ROM data AV Decoder (IC203) DRAM (IC810) AV Decoder (IC203) read matching check Error 03: Data write error 04: Data read error 05: Write/read data mismatch error 06: DMA transfer DREQ error 07: DMA transfer address error ROM (IC803) patterns are copied to all areas to be checked. Because of large DRAM (IC810) capacity, each time 256 bytes are copied, the addresses of copy source (ROM) are returned by 255 bytes. In detail check, to verify all bits in DRAM (IC810), the bit patterns are checked again after inversion. DMA is used when writing/reading the data. Though the bus width of AV Decoder (IC203) is 64 bits, the display is given in 8 bits. Namely, actual address is 1/8 of displayed data, and lower 3 bits indicate the byte position. Overwriting by the shadow can be detected, as the data are written to all areas, then read. In the detail check, all areas of RAM are checked twice by inverting the data, while in the simple check one block is checked, then subsequent 4 blocks are skipped, and also inverted data are not checked. If write/read mismatch error occurred, checking can be repeated.

(7-6) Connection from ARP (IC806) to 64020 ROM data ARP (IC806) Decrypt (IC811) AV Decoder (IC203) Error 04: Data read error 05: Write/read data mismatch error 06: DMA transfer DREQ error 07: DMA transfer address error 10: Chip-to-chip data transfer error AC-3 audio data stored in ROM (IC803) are written to the ARP (IC806), then whether they are transferred to the AV Decoder (IC203) is checked. If transfer error is not detected, the address of AV Decoder (IC203) to which data are transferred is displayed on the terminal. A part of data transferred to the AV Decoder (IC203) is read into Syscon RAM (IC802) through DMA, and compared with ROM (IC803) data. (7-7) Interrupt Line in 64020 AV Decoder DRAM (IC201, 202) (DMA COPY) AV Decoder DRAM (IC201, 202) another area Error 31: AV Decoder interruption is not detected Data transfer stop interruption which is generated through DMA copy of DRAM (IC201, 202) data in AV Decoder (IC203) to another area is detected. (8) Video Consumption Concerned (8-2) 1914 (Serial) Color bar output (color bar enable command) from Video Encoder (IC252) Error 11: Serial transfer error Using the Vsync interruption, serial communication to the Video Encoder (IC252) starts, and the color bar enable command is transferred to the 1914. The Vsync interruption and internal serial 1 interruption are used. If no error is found, the message is displayed to prompt for key entry. Check the color bar output. (8-3) 1914 Read ID read Existing data matching check Error 40: 1914 ID error The 1914 device ID is read. Error if the read value is not "1914 (hex)".
(8-4) 1914 Vsync CPU measures the 1914 Vsync interrupt cycle. Error 41: Vsync interruption is not detected 42: Vsync interrupt cycle error The number of interruption for 200 msec is counted, and if it is 11 to 13 times, this check is OK. It should be 12 times exactly, but ±1 errors are allowable. (8-5) Still Picture Output (SDRAM (IC201, 202) direct write) Pattern data AV Decoder (IC203) Video Out Error 31: AV Decoder (IC203) interruption (DMA transfer) is not detected The pattern is directly written to the SDRAM (IC201, 202) in AV Decoder (IC203), then its picture display is checked. First, the brightness signal data are written by the amount of one screen while changing every pixel. For the color difference signals, both Cr and Cb are set to 80h for monochromic pictures, and the display is turned on. Then, color difference signal data are written while changing the data every column. As both brightness signal data and color difference signal data take regular patterns, the processing speed is increased through DMA transfer of the repeated sections. Further, in detail check the color difference signal data written to the out of display area are copied through DAM transfer to change display colors successively. If no error is found, the message is displayed to prompt for key entry. Check the pattern output. (8-6) Still Picture Output (via ARP (IC806)) ROM picture data ARP (IC806) AV Decoder (IC203) Video Out Error 10: Chip-to-chip data transfer error ROM (IC803) data are transferred to the AV Decoder (IC203) via ARP (IC806), and the displayed picture is checked. If no error is found, the message is displayed to prompt for key entry. The output picture is same as the start-up picture. (8-7) DNR (Serial) (IC251) ROM picture data ARP (IC806) AV Decoder (IC203) DNR (IC251) Video Out (outline) Error 10: Chip-to-chip data transfer error Using special diagnostic command, the output still picture is transferred to the DNR (IC251) for checking. If no error is found, the message is displayed to prompt for key entry. This checking is made only for the players with DNR. The output picture used is same as that in (8-6) Still Picture Output. The colors will vary extremely, if DNR (IC251) is effective. For the players without DNR (IC251), the error code 0 is returned.

6-5. Drive Auto Adjustment
The drive can be automatically adjusted, except disc change and tangential skew adjustment. For a disc, use the disc for adjustment. In case of abnormality, press the [stop] key to stop adjustment. If the drive does not stop, prevent secondary failure by taking proper action such as disconnection of the power cable. This adjustment should be made after repair is finished and no trouble is present in the drive. A trouble, if present, causes NG and the adjustment to be aborted. As the secondary failure could occur, perform automatic adjustment after the drive is completely repaired. With the initial menu displayed, press [1] on standard commander, and the screen as shown in Figure 8 will appear.

The tray opens after the ENTER key is pressed and the initialization is finished. Then, place the DVD_SL disc for adjustment. Press the ENTER key to start adjustment. During adjustment, the tangential skew adjustment screen is displayed. Make this adjustment only when the pickup was replaced. As for adjustment, rotate the T-SKEW adjusting screw on the pickup so that the displayed jitter becomes minimum (CCW makes jitter smaller). Avoid extreme rotation or interference of screwdriver with the disc. After adjustment, a message to apply a screw locking agent will be displayed if jitter value is within the specification. Then, apply a drip of locking agent to the recess of screw. Hence, change discs following the given messages on OSD, and the adjustment is finished if there is no problem. Note that if "All" is selected, the data of previous adjustment are erased and initial values are set.
