SAFETY PRECAUTIONS
The following check should be performed for the continued protection of the customer and service technician.
LEAKAGE CURRENT 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 460 kohms, the unit is defective.

DIAGNOSTICS OF OPTICAL PICKUP AND REPLACING TRAVERSE UNIT
Make failure diagnostics of the Optical Pickup as follows.
If the laser drive current becomes more than 1.5 times of the initial value, the Optical Pickup should be replaced.
The laser drive current is registered on the seal attached to the rear of the Mecha. Unit.
In case of replacing the Pickup, change the whole part of the Traverse Unit.
No mechanical adjustment is necessary after the replacement.
Disc no read,

Note for Handling the Laser Pick-up
The protection for the damage of laser diode.
If you want to change the optical device unit from any other units, you must keep the following.
(1) It should be done at the desk already took measures the static electricity in care of removing the OPU's
(Optical device unit) connector cable.
(2) Workers should be put on the "Earth Band".
(3) It shold be done to add the solder to the short land to prevent the broken Laser diode before removing the
24P FFC cable.
(4) Don't touch OPU's connector parts carelessly.
Replacement of the Laser Pick-up (Traverse Unit)
Check the Iop (Laser drive current).
If the present Iop (current) value exceeds +50% of the initial value, replace the Traverse unit (Laser Pick-up) with a new
one.
Iop Measurement Method
When measureing Laser drive current (Iop), playback the discs (CD, DVD) described below, measure Iop for CD Laser and
DVD Laser by the test point (LD1 ~ LD4) on the DVD Main P.W.B.
Test Disc : DVD/DVDT-S01 or commercially available discs.
: CD/TCD-784 (manufactured by ALMEDIO INC) or commercially available discs.

Optical Pick-up Diagnostics and Replacement
When repairing, carry out failure diagnostics by following the procedure described below.
If the present value of the laser drive current is 50% up to initial value, it is the point of the pickup replacement.
In case of the pickup replacement, replace the Traverse Unit with no adjustment.
The initial value is indicated on the label on back side of Mecha.
NO DISC indicated, Playback not smooth, etc.

If the present value is less than 80mA, write on
the new label by hand, put on the new label over
the old label.
If the present value exceeds 80mA,
replace the Traverse Unit with a new one.
Cause: Damaged electrostatically when replaced.
