FAULT FINDING TIPS SONY KV32XBR45

SONY KV32XBR45

FAULT FINDING TIPS 

1. CONVERGENCE
SYMPTOM : KV32XBR45 convergence is way off in the horizontal direction
CURE : Unit has an open R789 a 18 meg 1/2 watt resistor for the Horizontal static convergence. The tech will have to make a resistor out of 3, 6.2 meg resistors.
2. CONVERGENCE
SYMPTOM: KV32XBR45 Unit has convergence of all vertical lines are displace horizontally. Tech replaced the CRT without authorization. This did not solve the symptom
 CURE: Suggest tech look for R789 and see if it is open It is on the on "C" board. It The value is around 10 meg. There are two different chassis and CRTs used for this model. If they have the older chassis type that requires H stat convergence (CRT board has H stat control) they need to order the older CRT as per the manual. If newer type (No H stat) then the new CRT as per Service Manual supplement -1 is needed. CRT 8-733-743-05 The H Stat is done using the Yoke ring magnets. I have attached the two Service Manual supplements, and the SB325R1.
3. CONVERGENCE
SYMPTOM: KV32XBR45 Unit has sever Horizontal static convergence error. TV cae to us from another shop where the CRT and flyback was replaced. Customer call us for secont opinion.
 CURE: Suggest tech look for R789 and see if it is open It is on the on "C" board. It The value is around 10 meg. There are two different chassis and CRTs used for this model. If they have the older chassis type that requires H stat convergence (CRT board has H stat control) I have attached the two Service Manual supplements, and the SB325R1. However none of them have show this resistor. We were able to install a resistor in this unit that was a two 10 megs in series. Trimming the value by adding another 10 meg in parallel with one of the other 10 megs. we were able to converge the set. Original part was not available.
4. CONVERGENCE
SYMPTOM: Unit has mis-convergence of red and blue vertical lines. They are displace horizontally. Tech replaced the CRT without correcting the symptom.
 CURE: R789 open H-state not operational. What I'm finding is a resistor that appears to be open on this "C" board It is R789 The value cannot be read nor is it listed in the ESI software parts list. Trying another value from 10 to 20 megohms. This resistor is in the ground return of the H-stat resistor that is installed in the CRT. Tech needs to try different values to try and make this set converge horizontally. This TV converged with a 10 megohm resistor.
5. CONVERGENCE
SYMPTOM: Unit has nis-convergence of red & blue vertical lines which are displaced horizontally. Tech replaced the CRT. This did not solve the problem.
 CURE: Suggest tech look for R789 and see if it is open It is on the on "C" board. The value is around 10 meg. There are two different chassis and CRTs used for this model. If they have the older chassis type that requires H stat convergence (CRT board has H stat control) they need to order the older CRT as per the manual. If newer type (No H stat) then the new CRT as per Service Manual supplement -1 is needed. CRT 8- 733-743-05 The H Stat is done using the Yoke ring magnets.
6.DEAD
SYMPTOM: Unit was dead. has shorted horizontal output and shorted Q601, & Q602 components in power supply replaced. After replacement unit will turn on but still has no secondary voltage output of power transformer. All relays click but no high voltage. Has sound.
 CURE: Tech needs to check the condition or RY602. RY602 is the switching relay that turn on and off the set. The relay is "HOT" switched. In other words one side of the relay is connected to power oscillator output that runs nearly 350 vac Peak to Peak at 90Khz. Once the relay is closed this energy is placed across the power output transformer and provides the drive necessary to produce the B+.Measuring the input voltage of the relay to "HOT' ground found it to be 150 volts DC mode. But on the other side of relay we has 3 volts DC mode. Unit has defective RY602 relay.
7 .GEOMETRY
SYMPTOM : Unit is trying to constantly adjust the vertical height and horizontal size intermittently.
CURE : When monitoring the E/W Pin output of the M board the signal was very instable. It was decided to replace IC351 the Jungle IC. This corrected the trouble.
8 . WEAK VIDEO
SYMPTOM : Sony KV32XBR45 Unit has a very faint picture But the OSD is fine. Problem shows up in the tuner and video input mode. Tech ordered Q401 but did not correct the symptom

CURE : There is video at the base of Q401 but not at the emitter. Q401 measures 9 volts on all elements. Base must be 4.5 volts. Transistor is in cut off. Bases and emitter are the same 9 volts. Unit has open R617 a 680 ohm resistor.

(2-2) Revision ROM revision number is displayed.- Error: Not detected. The revision number defined in the source file of ROM (At the beginning of mass production, the Flash ROM of IC205 is used, but midway it is replaced by the IC206 OTP ROM. IC205 or IC206) is displayed with four digits. Below IC205 are all IC205 or IC206.
(2-3) ROM Check Sum Check sum is calculated. Error: Not detected. The 8-bit data are added at addresses 0x000F0000 ~ 0x002EFFFF of ROM (IC205) and the result is displayed with 4-digit hexadecimal number. Error is not detected. Compare the result with the specified value.
(2-4) Model Type Model code is displayed. Error: Not detected. The model code read from EEPROM (IC201) is displayed with 2-digit hexadecimal number.
(2-5) Region Region code is displayed. Error: Not detected. The region code determined from the model code is displayed.
3. Peripheral
(3-2) Gate Array Check
Data write > read, and accord check Error 02: Gate array write/read discord Data 0x00 > 0xFF are written to the address 0xF of GA (IC601), then read and checked if they accord.
(3-3) EEPROM Check Data write > read, and accord check Error 03: EEPROM write/read discord Data 0x9249, 0x2942, 0x4294 are written to addresses 0x00 > 0xFF of EEPROM (IC201), then read and checked. Before writing, the data are saved, then after checking, they are written to restore the contents of EEPROM.
4. Servo
(4-2) Servo DSP Check Data write >  read, and accord check Error 12: Read data discord Data 0x9249, 0x2942, 0x4294 are written to the address 0x602 of RAM in the Servo DSP (IC701), then read and checked.
(4-3) DSP Driver Test Test signal data → DSP Driver Error: Not detected. Caution: Do not conduct this test with a mechanical deck connected. The maximum voltage is applied to the Servo Driver IC (IC801, IC802). If mechanical deck is connected, the motor and optics could be damaged. Disconnect mechanical deck following the output message, then enter specified 4- or 5-digit number from the remote commander, and press the [ E N T E R ]. The test is conducted only when the input data accord. Check the output level, then press the [ N E X T ] to finish the test. This test is skipped if “All” is selected. Supplement: How to disconnect mechanical deck Disconnect flat cables connected to the CN002 and CN003 of MB-82/85 board. Also, disconnect harness from the CN011.
5. Supply
Caution: Do not conduct this check with a mechanical deck connected. An access is made to the stream supply and servo control IC (IC303) and external RAM (IC304) using check data. If mechanical deck is connected, the motor and optics could be damaged. This check is also executed by the “All” menu item. Supplement: How to disconnect mechanical deck Disconnect flat cables connected to the CN002 and CN003 of DVD board. Also, disconnect harness from the CN011.
(5-2) ARP Register Check Data write >  read, and accord check Error 08: ARP register write, and read data discord Data 0x00 to 0xFF are written to the TMAX register (address 0xC6) in ARP (IC303), then they are read and checked.
(5-3) ARP to RAM Data Bus Data write > read, and accord check Error 09: ARP < > RAM data bus error Data 0x0001 to 0x8000 where one bit each is set to 1 are written to the address 0 of RAM (IC304) connected to the ARP (IC303) through the bus, then they are read and checked. In case of discord, written bit pattern and read data are displayed. If data where multiple bits are 1 are read, the bits concerned may touch each other. Further, if data where certain bit is always 1 or 0 regardless of written data, the line could be disconnected or shorted.
(5-4) ARP to RAM Address Bus Data write > other address read discord check Error 10: ARP > RAM address bus error Caution: Address and data display in case of an error is different from the display of other diagnosis (described later). Before starting the test, all addresses of RAM (IC304) are cleared to 0x0000. First, 0xA55A is written to the address 0x00000, and the address data are read and checked from addresses 0x00001 to 0x80000 while shifting 1 bit each. Next, the data at that address is cleared, and it is written to the address 0x00001, and read and checked in the same manner. This check is repeated up to the address 0x80000 while shifting the address data by 1 bit each. If data other than 0 is read at the addresses except written address, an error is given because all addresses were already cleared to 0. In this check, the error display pattern is different from that of other diagnosis; read data, written address, and read address are displayed in this order. However, the message uses same template, and accordingly exchange Address and Data when reading.
(5-5) ARP RAM Check Data write >  read, and accord check Error 11: ARP RAM read data discord The program code data stored in ROM are copied to all areas of RAM (IC304) connected to the ARP (IC303) through the bus, then they are read and checked if they accord. If the detail check was selected initially, the data are written to all areas and read, then the same test is conducted once again with the data where all bits are inverted between 1 and 0. If discord is detected, faulty address, written data, and read data are displayed following the error code 11, and the test is suspended.
6. AV Decoder
(6-2) 1930 RAM Data write > read, and accord check Error 13: AVD RAM read data discord The program code data stored in ROM (IC205) are copied to all areas of RAM (IC402, IC403) connected to the AVD (IC401) through the bus, then they are read and checked if they accord. Further, the same test is conducted once again with the data where all bits are inverted between 1 and 0. If discord is detected, faulty address, written data, and read data are displayed following the error code 13, and the test is suspended.
(6-3) 1930 SP ROM > AVD RAM > Video OUT Error: Not detected. The data including sub picture streams in ROM (IC205) are transferred to the RAM (IC402, IC403) in AVD (IC401), and output as video signals from the AVD (IC401). They are output from all video terminals (Composite, Y/C).
7. Video
(7-2) Color Bar AVD color bar command write > Video OUT Error: Not detected. The command is transferred to the AVD, and the color bar signals are output from video terminals. They are output from all video terminals (Composite, Y/C).
8. Audio
(8-2) ARP > 1930 Error 14: ARP > 1930 video NG 15 : ARP > 1930 audio NG
DRIVE AUTO ADJUSTMENT
On the Test Mode Menu screen, press [ 1 ] key on the remote commander, and the drive auto adjustment menu will be displayed. Normally, [ 0 ] is selected to adjust DVD (single layer), CD, DVD (dual layer), and SACD in this order. But, individual items can be adjusted for the case where adjustment is suspended due to an error. In this mode, the adjustment can be made easily through the operation following the message displayed on the screen. The disc used for adjustment must be the one specified for adjustment. However, for SACD disc, use the player with initial data if the disc is not available.
0. ALL
Select [ 0 ] and press [ E N T E R ] key, and the servo set data in EEPROM will be initialized. Then, 1. DVD-SL disc, 2. CD disc, 3. DVD-DL disc, and 4. SACD disc are adjusted in this order. Each time one disc was adjusted, it is ejected. Replace it with the specified disc following the message. Though the message to confirm whether discs other than SACD disc are adjusted is not displayed, you can finish the adjustment if pressing the [ S T O P ] button. During adjustment of each disc, the measurement for disc type judgment is made. As automatic adjustment does not judge the disc type unlike conventional models, take care not to insert wrong type discs. Also, do not give a shock during adjustment
