The electric parts mounted on the RX-53 board cannot be replaced or adjusted.

If the electric parts need to be replaced or adjusted, replace the entire unit.

1-9. Writing and Rewriting the PLD Internal Data

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.

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.

The part number of PLD (or ROM for PLD) in which data is not written yet, is shown in “ Spare Parts” of

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 “EPR” is 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)
