2. Before Repair and Adjustment

1. Turn off the power supply. Using a 10 , 10W resistor, connect

both ends of power supply capacitors (C701-704) in order to
discharge the voltage.

2. Before turning the power supply on, after completion of repair,

slowly apply the primary voltage by using a power supply voltage
controller to make sure that the consumed current at 50 Hz in NO
SIGNAL mode should be shown below with respectto
supplyvoltage230 V/240 V.

3. About the Protection Circuitry

The protection circuitry may have operated if either of the following conditions is noticed:

6

*No sound is heard when the power is supplied.
*Sound stops during a performance.
The functions of this circuitry is to prevent circuitry damage, for example, the positive and
negative speaker connection wires are “shorted”, or if speaker systems with an impedande less
than the indicated rated impedance of thisunitareused.
If this occurs, follow the procedure outlined below:

1. Press the STANDBY /ON button, switch to STANDBY mode.

2. Determine the cause of the problem and correct it.

3. Press the STANDBY /ON button once again, supply the power.

Note:

When the protection circuitry functions, the unit will not operate unless the STANDBY /ON
button is first switched STANDBY and then ON again.

This unit equipped with a self-diagnostic function which, in the event of a malfunction,
automatically displays a code indicating the nature of the malfunction.
Use this self-diagnostic function when servicing the unit.

6.1. To display the malfunction code

U70 DVD: Automatically displays on the

U70 DECK:tuner/amplifier when a

malfunction occurs. Refer to
Fig. 6-1.

F61: Automatically displays on the

tuner/amplifier when a
malfunction occurs. Refer to
Fig. 6-1.

Fig. 6-1

12

6.2. To return to the normal display

1. For U70 DVD/U70 DECK

- Press an any operation button on the tuner/amplifier.

STANDBY button), and then switch power back on again.

2. For F61

- If F61 is displayed, the power will automatically be switched
off and the standby indicator will light up.

- F61 will be displayed for 3 seconds, and then the clock will be
displayed.

- To re-display the code, switch the power on. F61 will be re­displayed, and then after 3 seconds the clock will be displayed
and the power will automatically switch off.

6.3. Display contents

6.3.1. U70 DVD, U70 DECK / (displayed automatically)

- Problem or condition
A bus-line communications error has occurred as a result of the
flat cables being inserted incorrectly, thus preventing the system
from operating.

13

- If U70 is displayed on the tuner/amplifier, the Cassette deck or DVD
Changer cannot be operated by remote control.

- Correction Procedure

1. To check for correct insertion of the flat cables.

- Insert each connectors until you hear a click.

- Insert the flat cables at the back of the unit in the order
indicated. Refer to Fig. 6-2.
Make sure the white side of the cables is on your right side.
Refer to Fig. 6-3.

Fig. 6-2.

Fig. 6-3.

2. Breakage of the flat cables. (Check and replace.)

3. If the problem is not corrected by items 1 and 2 above, this
indicates a faulty IC.
SA-DV290:
IC901 (C2BBFD000404)
SL-DV290:
IC401 (C2BBFD000402)
RS-DV290:
IC701 (M38503M2406F)
Check these ICs and replace.

6.3.2. F61

- Problem or condition
When the power switch is switched on, it automatically switches
back off, making it impossible to switch power on.

14

- Correction procedure
Faulty Tuner/Amplifier (SA-DV290) output IC (IC601).
(When a DC voltage is applied to speaker terminals.)

7. To Supply Power Source

This unit SA-DV290 is designed to operate on power supplied form system connected.
For system connection, refer to Fig. 7-1.

Fig. 7-1.

When the unit SA-DV290 has to test and service alone, use the following method to supply power
source.

1. Short the section between W902A Pin 3 and C740 (-) (GND). (Refer

to Fig. 7-2.)

2. Connect this unit to an AC power supply cord.

(This unit come to stand-by mode.)

3. Turn the unit ON.

Fig. 7-2.
