1. CONTRAST OF MISCELLANEOUS PARTS
NOTES: Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List. The mark found on some component parts indicates the importance of the safety factor of the part. Therefore, when replacing, be sure to use parts of identical designation. Screws adjacent to mark on product are used for disassembly. Reference Nos. indicate the pages and Nos. in the service manual for the base model. When ordering resistors, first convert resistance values into code form as shown in the following examples. Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%, and K=10%). 56 x 101 RD1/4PU 1 J 47 x 47k RD1/4PU 3 J R50 0.5 RN2H R K 1RRS1P 1 R 0 K Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 5.62k 562 x RN1/4PC F

See to following page

SYMPTOM
DETAIL No power. There is a possibility that it may smoke.
When the power MOSFET is damaged,protection circuit works and then the power condition turn into Stand-by. When the power is turned on in this condition, it will return to Stand-by after a few seconds.If the power is turned on repeatedly,smoke come out due tothe explosion of the capacitor, because 100V will be supplied to the capacitor during power on. 1 1) Change of AMP Assy (AZW7262) 2) Change of capacitors (C2013,C033,C053,C113,C2113) in V-AMP Assy 3) Paste of the white round label to around the serial label. (Difference by each model) Paste the Speaker sheet and Cushion circle on the rear panel. Circuit change of F-AMP Assy, R-AMP Assy and V-AMP Assy.

AMP ASSY(AZW7262)

R2526 See picture 8
Check if the above 3 resistors(R2526, R2546, R2510) are not close to B line Jumper wire in new AMP ASSY. If close, bend the registers to keep away from the Jumper wire.

Bend resistor to keep away from Jumper wire
Check if 3 resisters are not close to B line Jumper wire.
How to replace the capacitors in V-AMP ASSY
Since the foil pattern is easily damaged, cut the legs of the capacitor
before removing the solder.
Cut the legs of the capacitors by the wire cutter.
Note: Actually, the legs are shorter than shown in the picture.
If the solder is not removed well and try to remove the capacitor, the foil pattern is easily damaged.
Caution It is hard to recognize the damaged foil pattern visually. After cutting the legs of the capacitor, remove the solder and take out the legs carefully. Check the contact of the foil pattern by using multi-meter after replacing capacitors. (If foil pattern is damaged, replace V-AMP ASSY.)
4 Idle current adjustment procedure
<Adjustment point and preparation>
1 Since it is necessary to perform the Initial adjustment within 1.5 minutes after power on, confirm the procedure before the adjustment. 2 Perform the idle adjustment with no dummy load and no input signal. 3 Since adjustment value is different depending on the room temperature, confirm the adjustment value before the adjustment. 4 Make sure that the AC outlet is within +5% of AC power supply. ( If not, use variable AC power supply.) 5 Set up the remote control unit for Test Mode 1) Set USE-SETUP-SW to "SETUP" 2) Press [1] while pressing [INPUT/ATT] 3) Press [CD] ->[5]->[5]->[6]->[INPUT/ATT] 4) Set USE-SETUP-SW to "USE" Then the remote control unit can transmit the test mode command.

5 Check procedure after modification
* The following procedure is mentioned to check by one channel. However if the AC power supply is with in +5% and the capable of dummy load is enough, it is possible to check by 2 channels.
7 1) Performance Check Connect the Dummy Load (8ohm) to front Lch Connect the Oscilloscope to the Dummy Load Connect the signal generator to the Multi ch Input( Front L ch) * Signal Generator output signal : 1KHz Sine wave , approx. 400mVrms Turn the power on Make sure FL is displayed. Minimize main volume By using jog dial, select "Assign Set Up"--> "Multi Channel In" Select "MULTI CHANNEL IN" and Press MULTI JOG Select "BYPASS" by rotating MULTI JOG and then press MULTI JOG Press speaker button for 3 seconds. Check FL if the speaker impedance is set to 8ohm. If 6ohm is displayed on FL, switch to 8ohm Check the output Signal Select MULTI mode by pressing MULTI Channel In. Input the sine wave signal (1kHz, Approx. 400m Vrms) Turn the main volume gradually up and make sure to be clipped at nearly 28Vrms(80Vp-p) by oscilloscope. Also check if there is no distortion in wave form.
Note) Clip point is changed depending on the power supply voltage. If the Clip point is changed a lot, check the power supply voltage. 10 Check the remaining noise Connect the Milli Volt Meter to Dummy load. Turn the main volume to minimum and measure the remaining noise by the Milli Volt Meter. Standard : Less than 1.5mV 11 Perform the above procedure for Center ch, Front Rch, Surround Lch, Surround Rch Cancel the Multi mode by pressing MULTI Channel In. Operation check Connect Front L&R ch, Center ch, Rear L&R to speakers Connect digital output of DVD player to digital input (DVD) Turn the power on Play DVD (with source of Dolby digital software) Set STANDARD by pressing DSP mode button Turn main volume up and check if sound from speakers of all the speakers.
