CDX-656/656X SERVICING NOTES
NOTES ON HANDLING THE OPTICAL PICKUP BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic breakdown because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic breakdown and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care. NOTES ON LASER DIODE EMISSION CHECK The laser beam on this model is concentrated so as to be focused on the disc reflective surface by the objective lens in the optical pick-up block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens. US/Canadian model: If the optical pick-up block is defective, please replace the whole optical pick-up block. Never turn the semi-fixed resistor located at the side of optical pick-up block.

Magazine assy

DISC MAGAZINE GETTING OUT PROCEDURE ON THE POWER SUPPLY IS OFF
Remove the CASE (LOWER. T) beforehand 1) Press the lever (ML.S) assy in the direction of arrow A. 2) Removal the magazine assy.
Note: Take out the magazine only when the tray is completely within the magazine. If the disk or tray is sticking out, turn on the power and eject the magazine.

CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. Flexible Circuit Board Repairing Keep the temperature of the soldering iron around 270 C during repairing. Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). Be careful not to apply force on the conductor when soldering or unsoldering. Notes on chip component replacement Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be damaged by heat.

Installation

Precautions
Choose the mounting location carefully, observing the following: The unit is not subject to temperatures exceeding 55C (131F) (such as in a car parked in direct sunlight). The unit is not subject to direct sunlight. The unit is not near heat sources (such as heaters). The unit is not exposed to rain or moisture. The unit is not exposed to excessive dust or dirt. The unit is not subject to excessive vibration. The fuel tank should not be damaged by the tapping screws. There should be no wire harnesses or pipes under the place where you are going to install the unit. The spare tire, tools or other equipment in or under the trunk should not be interfered with or damaged by the screws or the unit itself. Be sure to use only the supplied mounting hardware for a safe and secure installation. Use only the supplied screws. Make holes of 3.5 mm (5/32 in.) only after making sure there is nothing on the other side of the mounting surface.

CDX-656/656X SECTION 4 MECHANICAL ADJUSTMENT
Elevator Height (Address) Adjustment
Note: This adjustments is necessary when the system controller (IC201), variable resistor (RV201), slider (R), slider (L), or chassis (ELV) was replaced for any repair.

Connection:

power supply (DC 14.4 V) master unit + GND

BUS cable

Adjustment Method: 1. Connect this set to the master unit (e.g. MDX-C7970/C7970R), load a disc magazine, and place the set vertically as shown below. 2. Connect the regulated power supply to the master unit, and turn the power on. 3. Press the DISC button on the master unit and select DISC 5. 4. At this time, if the elevator shaft does not position between comb teeth A and B at addresses 5 and 6 as shown below, adjust the following. 5. Press repeatedly the DISC + and buttons on the master unit so that the elevator shafts moves from address 6 to address 5, or from 5 to 6. At this time, adjust RV201 on the main board so that the elevator shaft positions smoothly between comb teeth A and B. 6. Further, place the set horizontally and make same adjustment as mentioned above. 7. After adjustment at addresses 5 to 6 is finished, check all operations from addresses 1 to 10 with the set placed vertically and horizontally respectively to confirm that the elevator shaft positions in a range between comb teeth A to B.

CDX-656/656X SECTION 5 ELECTRICAL CHECK
Note: 1. This check is performed with the set placed horizontally. 2. Power supply voltage: DC14.4 V (more than 3 A). 3. Be sure to use the disc YEDS-18 parts code: 3-702-101-01, but only when indicated.
Focus Bias Check Connection: RF Board (Component Side)
oscilloscope (AC range) + TP (VC) IC101

TP (RFO)

Procedure: 1. Connect the oscilloscope to TP (RFO) and TP (VC) on the RF board. 2. Put the set into play mode by loading the disc (YEDS-18). 3. Confirm that oscilloscope waveform is clear and check RF signal level is correct or not.
Note: Clear RF signal waveform means that the shape can be clearly distinguished at the center of the waveform. RF signal waveform VOLT/DIV: 200 mV TIME/DIV: 500 ns (10 : 1 probe in use) level: 1.4 0.3 Vp-p
When observing the eye pattern, set the oscilloscope to AC range and raise the vertical sensitivity so that it may be easily seen.
Tracking Offset Check Connection: RF Board (Component Side)
oscilloscope (DC range) + TP (VC) IC101

TP (TE)

Procedure: 1. Connect the oscilloscope to TP (TE) and TP (VC) on the RF board. 2. Put the set into play mode by loading the disc (YEDS-18). 3. Press the. , > buttons on the master unit, and check the traverse waveform*. 4. Confirm that the oscilloscope waveform is symmetrical on the top and bottom in relation to 0 V dc, and check this level.
