picture and return picture. The processing includes the phase adjustment using the line memory and  
exchange of the clock signal with another desired clock.  
The DPR-163 board has a built-in color bar generator and performs the processing of the marker and  
skin gate for the monitor.  
It also performs embedding of the prompter signal into the signal of the return video signals and the  
interface processing with the digital audio system.  
. SDI-54A/SDI-82 board

1-10. Circuit Protective Elements  
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.

forcibly, disconnection may result. Handle the cable  
carefully.  
The fans that are used in the unit of the rear panel are  
recommended replacement parts.  
The lifespan of these fans is about 30,000 hours, which  
means that the fans can be used for about three and a half  
years if the power is on all the time, so as a guideline the  
fans should be replaced every three and a half years.

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)
