1. Before Repairs
1. Turn off the power supply. Using a10 , 10 Wresistor, connect
both ends of power supplycapacitors (C717) inorder to discharge
the voltage.
2. Before turning the power supplyon, after completion of repair,
slowlyapplythe primaryvoltage byusing apower supplyvoltage
controller to make sure that the consumed current at 50 HzinNO
SIGNALmode (VOL: except for infinity, SELECT:DVD)shouldbe
shownbelow with respect to supplyvoltage 230/240 V.
Powersupply

2. Protection Circuitry
The protection circuitrymayhave operatedif eitherof the following conditions is noticed:
-Nosound isheard when the power isswitched ON.
-Sound stops during aperformance.
The functions of this circuitryis toprevent circuitrydamage if, forexample, the positive and
negative speakerconnection wires are shorted, orif speakersystems withanimpedance less
thanthe indicatedratedimpedance of this unit are used.
If this occurs, followthe procedures outlinedbelow.
1. Switch OFF the power.
2. Determine the cause of the problem and correct it.
3. Switch ONthe power once again.
Note:
Whenthe protection circuitryfunctions, the unit will not operate unless the poweris first
switchedOFF and thenON again.

6. Self-Diagnostic Function
This unit is equippedwitha self-diagnostic function which, inthe event of a malfunction,
automaticallydisplays a code indicating the nature of the malfunction.
Use this self-diagnostic function whenservicing the unit.
6.1. To displaythe malfunction code
U70 DVD:
Automaticallydisplayson the AVcontrol receiver when a
malfunction occurs. Refer to Fig. 6-1.
F61: / F76:
Automaticallydisplayson the AVcontrol receiver when a
malfunction occurs. Refer to Fig. 6-1.
Fig. 6-1.
6.2. To redisplaythe malfunction code
1. For U70 DVD
-Press some operation buttons on the AVcontrol receiver.
-To redisplaythe code, switch the power off (Standby/on
button), and then switch power back on again.
2. For F61/F76
-IfF61/F76 isdisplayed, the power will automaticallybe
switched off and the standbyindicator will light up.
-F61/F76 will be displayed for asecond, and then the clock will
be displayed.
-To redisplaythe code, switch the power on. F61/F76 will be
redisplayed, and then the clock will be displayed and the
6

power will automaticallyswitch off.
6.3. Displaycontents
6.3.1. U70 DVD
-Problem or condition
Abus-line communications error has occurred as aresultof flat
cablebeing inserted incorrectly, thus preventing the system from
operating.
-IfU70 isdisplayed on the AVcontrol receiver, DVD/CD player
cannot be operated byremote control.
-Correction Procedure
1. To check for correct insertion of flat cable.
-Insert connector until you hear aclick.
-Make sure the white side of the cableison your right side.
Refer to Fig. 6-2. Fig. 6-2.
2. Breakage of flat cable. (Check and replace.)
3. Ifthe problem isnot corrected byitems 1and 2above, this
indicates afaultyIC.
SA-DT310:
IC502 (C2CBKJ000061)
SL-DT310:
IC402 (C2BBFD000394)
Check these ICsand replace.
