Preventing static electricity 1.Grounding to prevent damage by static electricity Electrostatic discharge (ESD), which occurs when static electricity stored in the body, fabric, etc. is discharged, can destroy the laser diode in the traverse unit (optical pickup). Take care to prevent this when performing repairs. 2.About the earth processing for the destruction prevention by static electricity Static electricity in the work area can destroy the optical pickup (laser diode) in devices such as CD players.
Safety precaution ! CAUTION Burrs formed during molding may be left over on some parts of the chassis. Therefore, pay attention to such burrs in the case of preforming repair of this system. ! CAUTION Please use enough caution not to see the beam directly or touch it in case of an adjustment or operation check.

Adjustment method Caution : Replacing the pickup To prevent damage to the laser diode Caution : static electricity destroys the laser diode. Solder rejection or cuts a pattern with nipper at shortstop point after short Always take countermeasure performing repairs around the laser circuiting with clip with terminal face of pickup.
Maintenance of laser pickup (1) Cleaning the pick up lens Before you replace the pick up, please try to clean the lens with a alcohol soaked cotton swab. (2) Life of the laser diode When the life of the laser diode has expired, the following symptoms will appear.
Extension cord connecting method Using the extention cords to connect the front panel with the main board Remove the main board follwing the disassembly methode. Then reattachi the heat sink to main board. Using the 2pin extention cord (EXTLX001-2p), Using the jig board (EXTLX002-SWPWB), its connect the harness of the feed motor (L) assembly installing to the chassis, then using 4pin extention with the connector CN503 on the main board.
