5 Handling Precautions For Traverse Deck

TOP PREVIOUS NEXT

The laser diode in the traverse deck (optical pickup) may break down due to potential difference caused by static electricity of clothes or human body.

So, be careful of electrostatic breakdown during repair of the traverse deck (optical pickup).

  1. Do not subject the traverse deck (optical pickup) to static electricity as it is extremely sensitive to electrical shock.

  2. The short land between the No.4(LD) and No.5(GND) pins on the flexible board (FFC) is shorted with a solder build-up to prevent damage to the laser diode.To connect to the PC board, be sure to open by removing the solder build-up, and finishthe work quickly.

  3. Take care not to apply excessive stress to the flexible board (FFC).

  4. Do not turn the variable resistor (laser power adjustment). It has already been adjusted.
