1. HandlingPrecautions
o Since the heat sink and transistor metallic parts are connected to the Front Amp output, make sure they do not contact the GND (chassis)or other circuits. o Since there is residual high voltage in the Power Amp Module Assy +31 (FRONT ASSY FOR 100W) and +B2 (REAR, PWR, PRTEC ASSY) even when the power is OFF, caution should be exercised.(If necessary, the voltage should be discharged). a When handling the Power Amp Module Assy, make sure you do not touch the fan motor blade. I Front Amp Side (FRONTASSY FOR 1OOW)
itep I Measurement
2. Adjustment and Confirmationof ldle Current
o Basically, the idle crurent needs to be confirmed when replacing a power transistor, driver transistor, or bias transistor, or when the entire split board Assy of the Power Amp Module Assy has been replaced. o Make sure the heat sink has cooled sufficiently before measuring the idle current. (Temperature should be the same as room temperature; 25oC is ideal, if possible.) o Idle current stipulated value: 3-50mA.
Item
Short both sides of C7L23 afi C7L24 on the Rear Amp side. Insert a resistor (0.220, 3W or more) in series in the connector CN7502 *81 (or -81) line (terminalNo. 5 or 6). (Referto FiS.2-2.\

Short between the Point A pattern in Fig. 2-3 using solder. Short between the Point B pattern in Fig. 2-3 using solder. After performing Steps 8 and 9, remeasure the idle current and confirm that it is below 50mA.
Connect R7517 to R7515 in a parallel circuit. Connect R7518 to R7516 in a oarallel circuit.

NOTE:
If the idle current is below 3mA, support a resistor(33kQ) between the emitter and the Q7501(Lch) and Q7502(Rch) bias transistor base,and confirm that the idle cunent is within 3-50mA. 1-21

AJter performing Steps 8 and 9, remeasure the idle current and confirm that it is below 50m-{.
NOTE:
If the idle current is below 3mA, support a resistor (15kQ) between the emitter and the Q7101 (Center-ch) and Q7102 (Surroundch) base. and confirm that the idle current is within 3-50mA.
3. Adjusting the OperatingTemperatureSetting of the Fan Motor (VR77O1l
This adjustment is necessary when IC7403 (+12V regulator), Q7301 and Q7302 (temperature sensors), or VR7701 has been replaced, or when the entire split board Assy of the Power Amp Module Assy has been replaced. I Adjustment-Related Cautions a Make sure the heat sink has sufficiently cooled (is the same as room temperature Ta.) a Once the power has been turned ON, make measurementsand adjustments as quickly as possible, (If too much time is taken, the heat sink temperature will rise, and the measurementswill deviate from the Ta measurementpoint.) I Adiustment 1. Connecta voltmeter between TEMP and TP (or between IC7702 terminals No.3 and 2). (Refer to Figs. 2 3 and 2-6.) 2. Determine the fan motor operating temperature setting by means of the following formula. (Tolerance is within t30mV.) (85oC- Ta) x 19 (mV) Formula: ("C) Ta: ambient lemprature 3. Adjust VR7701 so that the voltage between TEMP and TP is the value obtained from the above Iormula.

1. Use a 10 : 1 probe for the oscilloscope. 2. All the knob positions (settings) for the oscilloscopein the adjustment procedures are for when a 10 : 1 probe is used.
O Test Mode
These models have a test mode so that the adjustment and checks required for service can be carried out easily. When these models are in test mode, the keys on the front panel work differently from normal. Adjustments and checks can be carried out by operating these keys with the correct procedure. For these models, all adjustments are carried out in test mode. lSetting these models to test model How to set this model into test mode. 1. When the Power switch to activated, set the FUNCTION button to CD. 2. Short-circuit between both CD TEST points. (See Fig. 1) When the test mode is set correctly, the display is different from vrhat it usually is when the power is turned If the display is still the same as usual, test mode has not been set correctly, so repeat Steps 1-2.

loperations of the keys in test model Code Key Name Function in Test Mode Focus servo close Explanation The laser diode is lit up and the focus actuator is lifted up, then lowered slowly and the focus servo is closed at the point where the objective lens is focusedon the disc. With the player in this state, if you lightly rotate the stopped disc by hand, you cao hear the sound the focus servo. If you can hear this sound, the focus servo is operating correctly. If you press this key with no disc mounted, the laser diode lights up, the focus actuator is pulled up, then the actuator is lowered and raised three times and returned to its original position. Starts the spindle motor in the clockwisedirection and when the disc rotation reachesthe prescribed speed(about 500rpm at the inner periphery), sets the spindle servo in a closed loop. Be careful. Plessing this key when there is no disc mounted makes the spindle motor run at the maximum speed, If the focus servo does not go correctly into a closedloop or the laser light shineson the mirror section at the outermost periphery of the disc, the same symptom is occurred. Pressingthis key when the focus servo and spindle servo are operating correctly in closed loops puts the tracking servo into a closed loop, displays the track number being played back and the elapsedtime on the front panel, and outputs the playback signal. If the elapsedtime is not displayedor not counted correctly or the audio is not played back correctly, it may be that the laser is shining on the sectionwith no sound recordedat the outer edge of the disc, that something is out of adjustment, or that there is some other problem. This key is a toggle key and open/close the tracking servo alternately. This key has no elfect if no disc is mounted.

Moves the pickup position tov/ard the outer diameter of the disc. When this key is pressed with the tracking servo in a closed loop, the tracking servo automatically goes into an open loop.

The pickup and disc remain where they are when this key is oressed. Stores Disc I in the CD magazine,then ejects the CD magazine. However, even tlough the CD magazine is ejected, the pickup does not return to the park position. Eveo if the CD magazineis mounted again, the pickup remains where it is. Open/close the disc tray.
