The write/rewrite method of the PLD (Programmable Logic Device) that is mounted on the DPR-163  
board (board suffix: -22 and later) supports the e-Production (EPR) system.  
If the parts listed below needs to be replaced and if PLD needs to be upgraded, contact your local Sony  
Sales Office/Service Center.  
n
The PLD that is mounted on the DPR-163 board (board suffix: -11 through -14) does not support the e-  
Production system. If you want to write/re-write the internal data of the PLD, contact your local Sony  
Sales Office/Service Center.  
n
The part number of PLD (or ROM for PLD) in which data is not written yet, is shown in Spare Partsof  
e-Manual.  
Therefore, if part replacement is required, write the data by the following procedure.  
In the case of the PLD type that runs on the program stored in external ROM, data needs not to be written  
only by replacing the part if the specific PLD only is defective.  
e-Production system has the advantages shown below.  
. To write/rewrite the PLD internal data:  
1. The standard fixture (cable) can be used.  
2. The standard software (PLD Download Tool) can be used.  
. The PLD internal data is controlled in the Sony Database Server under the name Project file  
(E_xxx_xxx_xx_xx).  
. The printed circuit board is equipped with the standard connector (EPR connector) to write the PLD  
internal data. The indication EPRis shown on the printed circuit board.

1-10. Circuit Protective Elements  
The positive characteristic thermistor (for power supply) functions as a circuit protective element on the  
AT-141, DPR-163, RC-86, IF-789A/789P (HKCU-901), FC-83 (HKCU-903) and LC-41 (HKCU-904)  
boards of the unit. The thermistor increases the internal resistance and limits the current flowing to the  
circuits when an overcurrent flows or when the ambient temperature increases and the element reaches  
the specified temperature. If the elements operates, turn off the main power and inspect the HDCU  
internal circuit. After removing the cause of the equipment abnormality and the temperature of the  
element decreases, turn on the power again and operate the unit correctly. It takes about 1 minute for the  
elements to cool down after the main power is turned off.

SAFETY CHECK-OUT  
After correcting the original service problem,  
perform the following safety checks before  
releasing the set to the customer :  
Check the 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 3.5 mA. 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 5.25 V, so  
analog meters must have an accurate low-  
voltage 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 20 V AC range  
are suitable. (See Fig. A)
