Notice that the minus side of a tantalum capacitor may bedamaged by heat.Flexible Circuit Board Repairing Keep the temperature of the soldering iron around 270 Cduring repairing. Do not touch the soldering iron on the same conductor of thecircuit board (within 3 times). Be careful not to apply force on the conductor when solderingor unsoldering.This appliance is classified as a CLASS 1LASER product.This label is located on the rear exterior.CAUTIONUse of controls or adjustments or performance of proceduresother than those specified herein may result in hazardous radiationexposure.SAFETY-RELATED COMPONENT WARNING!COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINEWITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND INTHE PARTS LIST ARE CRITICAL TO SAFE OPERATION.REPLACE THESE COMPONENTS WITH SONY PARTS WHOSEPART NUMBERS APPEAR AS SHOWN IN THIS MANUAL ORIN SUPPLEMENTS PUBLISHED BY SONY.RadioFans.CN 收音机爱 好者资料库3CX-JN331/JPK331TABLE OF CONTENTS1.SERVICING NOTES.42.GENERAL.73.DISASSEMBLY3-1.Disassembly Flow .93-2.Case (Side-L/R) . 103-3.Case (Top) . 103-4.Tray Panel. 113-5.CD Mechanism Deck (CDM74KS-F1BD81C). 113-6.Front Pack Block . 123-7.Back Panel Section . 123-8.MAIN Board. 133-9.Tape Mechanism Deck(CWM43FF13: JPK331)/(CWM43FR34: JN331) . 133-10.

Therefore, when checking the laser diode emission,observe from more than 30 cm away from the objective lens.LASER DIODE AND FOCUS SEARCH OPERATIONCHECKCarry out the “S curve check” in “CD section adjustment” and checkthat the S curve waveforms is output three times.SECTION 1SERVICING NOTESNOTES ON HANDLING THE OPTICAL PICK-UPBLOCK OR BASE UNITUNLEADED SOLDERBoards requiring use of unleaded solder are printed with the lead-free mark (LF) indicating the solder contains no lead.(Caution: Some printed circuit boards may not come printed withthe lead free mark due to their particular size): LEAD FREE MARKUnleaded solder has the following characteristics. Unleaded solder melts at a temperature about 40 C higherthan ordinary solder.Ordinary soldering irons can be used but the iron tip has to beapplied to the solder joint for a slightly longer time.Soldering irons using a temperature regulator should be set toabout 350 C.Caution: The printed pattern (copper foil) may peel away ifthe heated tip is applied for too long, so be careful! Strong viscosityUnleaded solder is more viscou-s (sticky, less prone to flow)than ordinary solder so use caution not to let solder bridgesoccur such as on IC pins, etc. Usable with ordinary solderIt is best to use only unleaded solder but unleaded solder mayalso be added to ordinary solder.MODELPART No.CX-JPK331: Mexican model4-252-231-2CX-JN331/JPK331: Chilean and Peruvian models4-252-231-3 MODEL IDENTIFICATION+RLRL Rear View PART No.RadioFans.CN 收音机爱 好者资料库5CX-JN331/JPK331HOW TO OPEN THE DISC TRAY WHEN POWER SWITCH TURNS OFF.SERVICE POSITION CD MECHANISM DECK CD mechanism deckstandCDMP3 CONNECT board1Remove the case (side-L).2Turn the loading gear in the direction of arrow A.A3Pull-out the disc tray.RadioFans.CN 收音机爱 好者资料库6CX-JN331/JPK331 FRONT PANEL SECTION AMP BOARD MAIN boardPANEL boardfront panel sectiontape mechanism deckSUB TRANS boardTRANS boardAMP boardMAIN boardfront panel sectionRadioFans.CN 收音机爱 好者资料库7CX-JN331/JPK331SECTION 2GENERALThis section is extracted frominstruction manual.
