batteries during initial check out procedures.
Leakage Current Check/Resistance Check
Before returning the unit to the customer, make sure you make either (1) a leakage current check or
(2) a line to chassis resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance
from chassis to either side of the power cord is less than 240 K ohms, the unit is defective.
WARNING: DO NOT return the set to the customer until the problem or located is corrected.
Protection of Eyes from Laser Beam
To protect eyes from invisible laser beam during servicing

Precautions
1. ESD Precautions in Repairing
1.1 Do not apply excessive pressure on the mechanical parts (moving parts), including the Pickup
Block, as extremely high mechanical precision or required in these parts.
1.2 When soldering the microprocessor and signal processing IC’s, use a ceramic soldering iron or
a soldering iron whose metal part is grounded since they are not resistant to static electricity.
1.3 When removing the solder or soldering the laser shorting lands for the Pickup Block, use a
ceramic soldering iron or a soldering iron whose metal part is grounded since the laser diode or not
resistant to static electricity.
2. DVD Loading Unit Precautions when handling the Mechanism Block

the part with the liquid that contains 50% each of alcohol and water.
When removing the Mechanism P.C.B. Ass’y, you need to short-circuit the laser diode shorting
lands beforehand.
