    (4)Flap adjustment of the Pick-up guide shaft Attention !! RDV-985 is adjusted from issue machine because of the FL display on the way. Please go in the adjustment method before changes according to the following procedures. Mode Measurement Disc Adjustment point CN104 pin"1"...
  • Page 5 Confirmation after adjustment. Confirm to reproduce video CD and CD after the DVD test disc is adjusted and to find abnormality. Fig.2 (5) About keeping the disc As for the DVD test disc, plane accuracy is demanded.Please note the keeping place on the disc. Please do not put the disc directly on the work desk etc.
  • Page 6: Check Points For Each Error

    Check points for each error (1) Spindle start error *Defective spindle motor Are there 10ohms resistance between each pin of CN101 "29~31"? (The power supply is turned off and measured.) *Hall element: Is sine wave output between CN101 "23" and "24", between "25" and "26", and between "27"...
  • Page 7 (3) Traverse movement NG * For automatic adjustment, traverse movement occurs only when the position is changed to retry judging the disc type after the 1st judgment resulted in an error. Therefore, traverse movement rarely occurs because, in most cases, disc judgment at the current position (1st time judgment) is executed successfully.
  • Page 8 (6) Spindle CLV NG * When the spindle cannot be shifted to CLV Servo, does not become "H" between IC301 "69" and IC201"37". * IC201 Is signal output from CN103 "1" (RFOP)? * IC201 Is signal output from CN103 "11" (DSLIP)? * IC201 Is signal output from CN103 "6"...
  • Page 9 (9) Neither picture nor sound is output * Cannot search a) Can the feed system be driven? Chec k the waveform of TRSDRV signal (R273). --- Waveform between R274 and C271. Search results in a change of duty (three v alues with 2.5V at the center) (The figure is e xaggerated.)
  • Page 10 (10) Picture is distorted or abnormal sound occurs at intervals of several seconds. Does JITOUT change periodically? Some system other than servo may be (2V or more in peak defective. value, except during kick) Feed system is defective (drive gain is defective: too large). Check the waveform according to a) in (9).
  • Page 11: Precautions For Service

    Precautions for Service Handling of Traverse Unit and Laser Pickup 1. Do not touch any peripheral element of the pickup or the actuator. 2. The traverse unit and the pickup are precision devices and therefore must not be subjected to strong shock.

    2. Power Supply Volume With all the wiring removed, check unit power board. (1) Remove all flat wires and wire assemblies which are connected to CN801, CN805, CN806. (2) Short -circuit CN805"4" (POWER ON:B168) and "5" (B5V:B167). (Set each regulator to ON.) The load resistance is connected between CN805"5"(B5V:B167) and "8,9"(D.GND:B164).
