Flexible Circuit Board Repairing Keep the temperature of the soldering iron around 270C during repairing. Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). Be careful not to apply force on the conductor when soldering or unsoldering. Notes on Chip Component Replacement Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be damaged by heat. TABLE OF CONTENTS 1. SERVICE NOTE. 3 2. GENERAL Playing a CD right away! . 4 3. DISASSEMBLY 3-1.

During repair, pay attention to electrostatic breakdown and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care. NOTES ON LASER DIODE EMISSION CHECK The laser beam on this model is concentrated so as to be focused on the disc reflective surface by the objective lens in the optical pick-up block. Therefore, when checking the laser diode emis- sion, observe from more than 30 cm away from the objective lens. To Check the Laser Diode and Focus Search Operation Open the upper panel. Turn on the power without a disc while the main board S801 (OPEN) is ON (or TAP802 is shorted). Then, observe the objective lens and check that the following opera- tions are performed. 1.Scatterd light of laser beams is seen. 2.Check for vertical movements (five) of the objective lens (with movement of the PU on the inner circumference). Before Replacing the Optical Pick-Up Block Please be sure to check throughly the parameters as par the “Opti- cal Pick-Up Block Checking Procedures” (Part No.: 9-960-027- 11) issued separately before replacing the optical pick-up block. Note and specifications required to check are given below. FOK output : IC601 eg pin When checking FOK, remove the lead wire to disc motor. When checking FOK value, remove the lead wire to disc motor. RF signal P-to-P value : 0.46 - 0.66 Vp-p The repairing grating holder is impossible.

(Part No. : 3-702-101-01) 3.Press the N button. 4.Confirm that the oscilloscope waveform is as shown in the figure below. (eye pattern) A good eye pattern means that the diamond shape ( ) in the center of the waveform can be clearly distinguished. RF signal reference waveform (eye pattern) Test Points: When observing the eye pattern, set the oscilloscope for AC range and raise vertical sensitivity. 10 11 12 D-E200/E201/E206CK/E251 5-2.
