Subject: NVM User Manual Rev.2 Date: January 10, 2002
Symptom:
(xxxx) The NVM Jig User Manual was updated, to Revision 2.
NOTE: Please refer to the updated General Bulletin 31 for the connection and
switching information. This can be found under model GENTVP.
Solution: Revision 2 of the NVM Manual is below. This Non Volatile Memory jig allows the
servicer to read and write adjustment information from an EEPROM. This is
especially useful when a board from a projection TV containing the convergence
information is replaced. If the memory chip is not changed or read the entire unit
would have to be re-converged from scratch.
The part number for the NVM Jig is T-935-010-91 (List price is $160.00)
HARDWARE
Green LED: Read light indicator
Yellow LED: Write light indicator
Red LED: Power light indicator
Read Switch: Toggle push button Switch for Reading from Target NVM
Write Switch: Toggle push button Switch for Writing to Target NVM
Toggle switch: Power switch
Connector: RJ45 connector for both the SOIC and DIP cables
Test clip provided for connection to the RST pin on the Microcontroller.
9VB: 9 Volt Battery
SOIC Connector: For use with NVM chips that are Surface Mount
DIP Connector: For use with NVM chips that are Through Hole.

SETTING THE DIP SWITCH
Pins 1 and 2 will be dedicated to selecting between RA-4 XBR models and all other models due to NVM
differences.
Pins 3 and 4 will be dedicated to allowing pull up resistors for the target NVM chip if the chip is not getting
power on board.
There are diagrams for these selections located on page 5 of this manual.
CONNECTION TO THE NVM CHIP
For the prototype, the following color wires should be connected to the following pins:
PIN1 A0 BLUE/WHITE
PIN2 A1 BLUE
PIN3 A2 GROUNDING WIRE FOR RESET PIN
PIN4 GND ORANGE/WHITE
PIN5 SDA BROWN/WHITE
PIN6 SCL BROWN
PIN7 WP GREEN
PIN8 VCC GREEN/WHITE
Plug in bus connector headshell and select first bus by moving switch in the up position, second bus is
selected by placing switch in the down position. +5 volts and gnd are supplied by the jig for power and signal
setting purposes.
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
TV Products Service Bulletin No. 449R1
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.
If there is an error indication ensure that the connector is attached properly.
That the Microprocessor on the board is disabled.
Try added or subtracting the pullup resistors on pins 3 and 4 of the DIP switch.
Turn the unit on and then back off again and try reading again.
This error will occur when the NVM has not acknowledged any of the addresses for our
NVMs. These addresses range from A0 hex to AE hex.
When communication has been interrupted between the JIG and NVM
And when the data does not compare properly between the JIG and Target NVM.
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)
1 2 3 4
OFF OFF OFF OFF
RA-4 XBR BD board NVM MODE, PULLUPS
1 2 3 4
ON OFF ON ON
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.
1 2 3 4
OFF OFF ON ON
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.
TV Products Service Bulletin No. 449R1
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.
