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).

2.1 Handling of traverse deck (optical pickup)

 

2.2 Grounding for electrostatic breakdown prevention
