11、 SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUB- LISHED BY SONY. SECTION 1 SERVICING NOTES The laser diode in the optical pick-up block may suffer electro- static break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repai

12、r, pay attention to electrostatic break-down 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 focu

13、sed on the disc reflective surface by the objective lens in the optical pick-up block. Therefore, when checking the laser diode emis- sion, observe from more than 30 cm away from the objective lens. LASER DIODE AND FOCUS SEARCH OPERATION CHECK Carry out the “S curve check” in “CD section adjustment”

14、 and check that the S curve waveforms is output three times. Notes on chip component replacement Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be dam- aged by heat. Flexible Circuit Board Repairing Keep the temperature of the soldering iron around

15、270 C dur- ing 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 HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT RadioFans.CN 收音机爱 好者资料库 4 POWER SUPPLY DURING

16、SERVICING As this set has not own power supply, it does not operate inde- pendently. Therefore, during servicing, connect it to the Pre-Main ampli- fier Unit (TA-EX880/MS717) of DHC-EX880MD/MD717. Also, connect the Tuner Unit (ST-EX880/MS717) because the POWER switch is not provided to the Pre-Main

17、amplifier Unit (TA-EX880/MS717). If TA-EX880/MS717 and ST-EX880/MS717 are not available, use the Power Feed Jig (PFJ-1). In this case, turn on the POWER switch on the Power Feed Jig, then press button and CLEAR button on the set simulta- neously, so that the power is supplied. Connection: Set Pre-Ma

39、Note: Try to measure several times to make sure that the ratio of A : B or B : A is more than 10 : 7. Take sweep time as long as possible and light up the brightness to obtain best waveform. SECTION 4 TEST MODE SECTION 5 ELECTRICAL ADJUSTMENTS AGING MODE 1.How to Enter AGING Mode 1) Insert a disc in

40、to the CD player. (Multiple discs can be inserted *1) 2) With the set turned on, press button, CD3 button, and (CD2) button simultaneously, and the AGING mode is set. (*1): The AGING mode is active only to the trays where discs exist. 2.How to Exit from AGING Mode Turn off the Power, and normal oper
