General Items 1) Be careful not to have your eyes or a part of body touch withlaser diode at repair because this product uses laser diode. 2) Do not disassemble Pick-up at repair. If the laser diode is bad, replace the entire Pick-up. 3) Keep away from TV or other electrical units at repair to prevent influence from surrounding units. 4) If you replace the parts during repair, be sure to unplug the power cable before replacement. 5) If you insert a disc into the drive, be sure to load it corectly. 6) IThis tool is essential to check actions after installing PC hardware(more than CPU-Pentium ), using exclusive "Device Drive Instruction" supplied by CD, because this tool donsn't work, individually 7) This unit has many parts with features related to safety and especially, for essential parts, the importance is indicated on circuit diagram and part list. Be certain to use the parts with same specifications at replaing these parts. 2. Earthing cautions at handling Pick-up - Because the laser diode in optical Pick-up is subject to get out of order due to the potential difference occurring by electricity load charged in clothes or bodies, observe the following earthing items at handling. 1) Body earthing(hand) : Be sure to wear a wrist strip with one side earthed.(Impedance : Below 104). It removes the electricity formed in body. 2) Work table earthing : Put the earthed conductive plate (Impedance : Below 104) such as copper plate on work table. 3) Cautions for clothes : Do not have any clothes touch with Pick-up because the electricity formed in clothes is destroyed easily. 1

TroubleShooting Check the power source and initial state. Is electrity of 5V and 12V normally input after the connecting the power cable ? Y Do Y302 oscillate ? Y Dose the voltage of the 158pin of IC304 (initial power on) change from 5V to 0V ? Y Dose the voltage of the 58pin of IC304 change from 0V-5V-0V ? Y Is electricity of 3.3V normally output from the 3pin of IC103 ? Y When you transfer the P/U to the outer cycle, and turn the power on, dose it move to the inner one? Y TRAY IN/OUT ? Y LASER DIODE ON ? Y FOCUS UP/DOWN ? Y FOCUS LOCK ? Y DISC rotation? Y SPINDLE LOCK ? Y AUDIO OUTPUT ? N Refer to `NO AUDIO OUTPUT' N Refer to `NO SPINDLE MOTOR ROTATION' N N N Refer to `NO FOCUSE LOCK' N Refer to `NO LASER DIODE ON' N Refer to `Check TRAY OPEN / CLOSE' N N If the power of IC103(1pin) 5V is normal when you check, replace IC103. N Check out IC304(58pin) change from 0V-5V-0V. C201(11pin). N If the power of IC304(158pin) is normal when you check circuit. N If the power of Y302 is normal when you check, replace X-TAL. N Check the connection of the power short and cable. Refer to `NO SLED OPERATION' 18 No sled operation When you transfer the pick-up to the outer cycle and turn the power on, dose the P/U move to the inner one ? N The below waveform is outputted in IC304 14, 15pin, R339(PWMOUT1) R303(PWMOUT2) ? Y N If the constant of IC304 and GND, pattern's when you check, replace. Y SLED operation of normal. The below waveform is outputted in IC505 5, 6, 9, 10pin ? Y N If the constant of IC505 and GND, pattern's when you check, replace. Y Replace stepping Motor.
