The IC5, IC21, and IC60 in the DVD unit (X37-1120-03) are not replaceable components. In case of defectiv

5、e of any of these ICs, replace the DVD mechanism assembly. (The IC5 has a device key, which shall be made consistent with the S/No. of the mechanism assembly after replacement. Thus you cannot replace only the board.) MICROCOMPUTERS TERMINAL DESCRIPTION, TEST MODE, ADJUSTMENT are the same as KVT-719

8、the parts or components that are shown in this document.1. Replacement of motor fl at springWhen mounting the flat spring that shall be in contact with the worm gear, press the spring toward the direction shown with an arrow so that there will be no gap between the tip of the gear and the spring and

9、 then mount the spring. The gear shall be pressure-inserted into the motor. Note that there are two motors. Above operation of mounting the fl at spring is required on both of them.

Insertion of sliderThis subsection describes cautions for inserting the slider (slide section inside of the unit) into the outer chassis. 1) On the rail at the left side of the slider, there is a part called

15、a stabilizer that is used to minimize play in right and left sides.The slide is made of resin. (Note that the rail is shown at the right side of the slider in the picture.) When inserting the slider, press the stabilizer towards the direction shown with a blue arrow and insert it into the groove on

16、the rail.2) PCB holder is pushed out towards the downside of the picture due to the spring force and thus the chassis and photo refl ection sheet may be get caught by the holder during the assembly. Insert the slider while slightly lifting up the holder with a pair of tweezers or any other similar d

17、evice.3) Insert the gear after confirming that the both of D shaft gears at the right and left sides of the slider are aliened with the tip of the right and left racks on the chassis.(Otherwise the slider will be inserted sidelong.(Slider -Slide section inside of the unit)StabilizerPCB HolderThese p
