Maintenance of DVD pickup

1. Cleaning of pickup lens

(1) Prior to changing the pickup, clean the pickup lens.

2. Confirmation of the service life of laser
diode when the service life of the laser
diode has been exhausted, the following
symptoms will appear.

(1) The RF output (EFM output and eye pattern amplitude)
will become lower.

(2) The drive current required for light emitting of laser diode
will be increased.

Confirm the service life according to the following flow chart:

Is the RF output

1.25 0.22VP-P?

Change the pickup

NO

YES

OK.

3. Semi-solid state resistors on
the APC P.C. board

The semi-solid state resistor on the APC P.C.board

attached to the pickup is used for adjusting the laser
power. Since these resistor should be adjusted in
pair according to the characteristics of the optical
block, be sure not to touch on the resistors.

Since the service life of the laser diode will be
exhausted when the laser power is low, it is
necessary to change the pickup. Meanwhile, do not
pickup. Otherwise, the pickup will be damaged due
to over current.

Procedures of changing
the DVD pickup

The power switch is turned off,

and the power code is pulled out from the outlet.

Change the DVD pickup by referring

to "Removing the DVD pickup" in the

Disassembly Method.

The power code is inserted, and the power switch is
turned on. It is confirmed that the laser emits light
for about three seconds at that time, and object lens
moves vertically.

Completion the disc.

It is confirmed to be able to observe the shape of
waves of the eye pattern to TP602.

Completion of changing the DVD pickup.

Therefore, besure to perform not only adjustment and

operation of this system so carefully as not to directly

look at thelaser beam or touch on the body.
