PCB PARTS LIST 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. ÷ 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%). 560 Ω = 56 × 10 1 = 561 ................................................... RD1/4PU 5 6 1 J 47k Ω = 47 × 10 3 = 473 .................................................. RD1/4PU 4 7 3 J 0.5 Ω = R50 ...................................................................... RN2H Â 5 0 K 1 Ω = 1R0 ......................................................................... RS1P 1 Â 0 K Ex. 2 When there are 3 effective digits (such as in high precision metal film resistors). 5.62k Ω = 562 × 10 1 = 5621 ...........................................

User display None A0 None A1 A3 Description • A disc couldn’t be detected for playback after loading because; No disc existed. A disc was turned upside down. A disc was dirty. A disc was loaded incompletely. • The focus got out of place during playback due to the crack and stain on the disc. • The servo mechanism couldn’t move to the desired tune position within a fixed time during selection of a tune from playback or during playback. • A disc couldn’t be loaded within a fixed time. (A disc couldn’t be carried from the rack block.) U1 A4 • A disc couldn’t be unloaded within a fixed time. (A disc couldn’t be returned to the rack block.) A2 • The LOADING mechanism couldn’t move to the desired disc position within a fixed time during selection of a disc from playback or during playback start from stop. User display None A7 None A8 None A9 None AA Description • Mechanism position just before the LOADING mechanism shifts to the disc selection operation when the DCNT pin is low. (The DCNT pin is usually high when the LOADING mechanism is in the stop state. The mechanism position is thus judged to have been shifted for some reason. The shifted mechanism position may cause a failure.) • Discrepancy has occurred between the detected disc position and the current disc position during movement of the loading mechanism. (The system may incorrectly counted the waveforms of the DCNT and DPOS terminals. If counting is incorrect, the position of the disc No. displayed does not match the disc position counted.) • Mechanism position during disc loading when the DCNT pin is low. (The DCNT pin is usually high when the LOADING mechanism is in the stop state. The mechanism position is thus judged to have been shifted for some reason. The shifted mechanism position may cause a failure.) • The pickup block cannot return to the innermost circumference when the playback is completed or another disc is shifted. U2 A5 None A6 • The LOADING mechanism couldn’t be forcibly returned to the home position (left position when viewed from the front) within a fixed time after it is initialized or becomes NG. • A disc couldn’t be normally rotated for playback after loading because; A disc was turned upside down. A disc was dirty A disc was loaded incompletely. • A disc couldn’t be normally rotated during playback due to the crack and stain on the disc.
