LASER BEAM SAFETY PRECAUTIONS

CLASS 1 LASER PRODUCT

CAUTION
Invisible laser radiation when the unit is open.
Do not stare into beam.

CAUTION: USE OF ANY CONTROLS, ADJUSTMENT, OR
PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN
MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.

Do not look directly at the laser beam
coming from the pickup or allow it to

FL8550

strike against your skin.

This compact disc player uses a pickup that emits a laser beam. The laser beam is emitted from the
location shown in the figure. When checking the laser diode, be sure to keep your eyes at least 1 foot away

from the pickup lens when the diode is turned on. Do not look directly at the laser beam.

CAUTION:

Using controls and adjustment, or doing procedures other than those specified herein, may result in
hazardous radiation exposure.

This symbol is intended to alert the user to
the presence of uninsulated "dangerous
voltage" within the product's enclosure that
may be of sufficient magnitude to consti­tute a risk of electric shock to persons.

This symbol is intended to alert the user to
the presence of important operating and
maintenance (servicing) instructions in the
literature accompanying the appliance.

Caution: To p re v e nt e l e ct r i c s h o ck d o not use this

(polarized) plug with an extension cord, recep­tacle or other outlet unless the blades can be
fully inserted to prevent blade exposure.

expose the unit to rain or moisture.

HANDLING LASER PICKUP

The laser diode in the optical system of this player can be damaged by electrostatic discharge from
your clothes or your body. Proper electrostatic grounding for service personal is required during servicing.

BEFORE REPAIRING THE COMPACT DISC PLAYER

Preparation

Human Body Grounding:
Many of the components used in this compact disc player, including the laser pickup, are sensitive to
electrostatic discharge. Service personal should be grounded with an electrostatic armband (1 Mohm).

Caution:
Static charge on clothing does not escape through a body grounding wrist band.
Be careful not to contact the pickup or electrical components with your clothing.

Workbench and Tool Grounding:
A properly-grounded electroconductive plate (1Mohm) or metal sheet should be fitted to the workbench
surface. Tools and instruments (such as soldering irons and scopes) should be grounded to prevent AC

leakage.

Note: Laser diodes are so susceptible to damage from static electricity that, even if a static discharge does
not ruin a diode, it can shorten its life or cause it to work improperly.

Service Bulletin

Service bulletin # H/K9901 Rev1 November 2002

Warranty Labor Rate: Major Repair
To: All harman/kardon Service Centers
Models: FL8350/FL8550
Subject: “No disc” reading in display

When a CD is in the carousel at the play position, Infra red light emitted by IR LED D3 is reflected onto IR Photo
sensor D2. D3 and D2 are on the PCB located underneath the carousel. When the amount of IR light received
by D2 is insufficient, D2 will not saturate and the display will read “No disc”.

In the event you receive an FL8350 or FL8550 with the complaint: Display reads “No disc” but a disc is in
the tray, perform the modification as listed below:

Lay the unit on a padded surface.

1)

2)

Remove the (7) Black Philips screws holding the Top Cover on; remove cover.

3)

Lay unit on its side and remove (5) Black screws on bottom which hold front panel to chassis.

4)

Lay unit upright, remove (2) Black screws at top front section holding front panel to the front tray retainer brackets.

5)

Pull front panel away, cut plastic cable ties if necessary, and lay the front panel face down on the table.

6)

Remove (4) tray retainer brackets, (1) Plated screw each. (Bracket on left side may have a ground terminal).

7)

Pull the carousel tray up and out of the unit; turn upside-down to expose the sensor board.

8)

Remove the (2) Plated screws holding the sensor board to tray.

9)

Lift the board and unplug either molex connector CN1 or CN2 to be able to turn board upside-down.

10)

Locate R1 and change from a 470Ω to a 750Ω resistor - h/k part# 1007-501316-000.

11)

Locate R2 and change from a 750Ω to a 470Ω resistor - h/k part# 1004-701316-000.

Alternately, the two above parts may just be “swapped”, as this will result in the correct values.

12) Locate D3 and replace with new infra-red LED - h/k part# 3100-204000-002.
REASSEMBLY:

13) Replace sensor board, screws, and CN1 or CN2 connectors.

14) Turn the carousel tray over and replace back in the track; tray must be positioned all the way at the rear of the unit.
When placed correctly, tray should not glide back & forth on the track.

15) Replace and attach the (4) tray retainer brackets with single screws - ground wire (if present) is re-attached to left
front bracket.

16) Replace the front panel, both with the (5) bottom screws and the (2) screws at the top. Note: Make sure any
washers that were present between the various brackets and the chassis are reinstalled. Replace cable ties as
necessary.

17) Test the player by inserting one or more compact discs, assure unit reads discs in all slots.

18) Locate MCU board, which is mounted vertically on right side of unit. Connect DC Multimeter to Pin 8 (gray wire) of
CN705 (10 pin plug, labeled 'DSNS'), and Pin 2 (red wire) of CN701 (2 pin plug). While playing a disc, DC Multimeter
reading must be between 4.7 V and 5.0 V.

19) Replace top cover and screws.

To: All harman/kardon Service Centers

Models: FL8350/FL8550

Subject: Carousel does not stop

In the event you receive an FL8350 or FL8550 with the complaint: “The carousel does not stop at a given
disc position, …or passes disc positions intermittently”, perform the modification listed below:

1) Lay the unit on a padded surface.

2) Remove the (7) Black Philips screws holding the Top Cover on; remove cover.

3) In the center of the carousel are a single screw and plated washer; remove these.

4) Underneath the larger plated washer are two smaller fiber washers. These are to be removed permanently.

5) Examine the larger plated washer carefully. Upon replacement of the larger plated washer and screw, make
sure the slightly sharper, stamped edge of the washer is facing upwards.

6) Test the player by inserting one or more compact discs, assure the unit reads discs in all slots, and stops at
all positions.

IF THIS MODIFICATION DOES NOT CORRECT THE PROBLEM

7) Lay unit on its side and remove (5) Black screws on the bottom, which hold the front panel to the chassis.

8) Lay unit upright, remove (2) Black screws at top front section holding front panel to the front tray retainer
brackets.

9) Pull front panel away, cut plastic cable ties if necessary, and lay the front panel face down on the table.

10) In the center of the carousel, once again remove the single screw and plated washer.

11) Lift the carousel up and off the chassis, towards the front of the unit.

12) Turn the carousel upside-down; in the center is a hollow plastic post. Remove any excess lubricant with a
clean dry cloth or paper towel, saving it for re-application. The end of this post must be filed down
approximately 0.020” (0.5mm) with a file, Dremel tool, or similar tool. Be sure not to remove too much
material and keep the surface even (flat). Remove any debris or shavings when finished.

13) Spread and replace the saved lubricant on the new surface of the center post.

Troubleshooting tips and solutions to common service problems

For models: FL8350/FL8550/FL8380 TIP# HKTT2003-06

Complaint: Unit Will Not Play or Recognize a Disc, “Skipping”.

Possible Problem: Misalignment of the top cover and rear panel.

To test, attempt to play the unit with the top cover OFF. If symptoms persist, troubleshoot further. If the
unit will play with the cover OFF, the problem is caused by a misalignment of the top cover and the rear
panel. When the screws are tightened on the top cover, at the rear of the unit, the CD mechanism may
“warp” upward in the area of the clamper arm, which causes a “Will not Play” symptom, which shows up as
an unusual delay, with the word “Disc” in the display, after the “Play” button is pressed.

TECH TIPS

Solutions:

Washers can be added to the top rear screws to fill the gap between the top cover “lip” and rear panel.
Alternately, a spacer can be constructed of fish paper, plastic sheet, or similar material, that will fit
between the Disc Clamper and the inside of the rear panel. Choose thickness as necessary.

Circuit Description

1. RF AMP BLOCK

The KA9220 is designed for 3-spot type optical pick-up assembly. The photo detector is composed of 6
light sensor (A through F). The photo detector A, B, C and D detect audio modulation signal on the disc
and generate focus error signal.

RF I-V AMP (1) and RF I-V AMP (2) are converted current of PD1 (A + C) and PD2 (B + D) through the
58 Kohm Internal resistor into Voltage.
Furthermore, they are added to RF Summing amplifier.
This signal (A + B + C + D) is outputted from RFO (Pin66).
The output Voltage is as follow.

The output of photo detector F is directed to the (-) Input of F I – V AMP and out of photo detector E is
directed to the (-) input of E I – V AMP.
These input signals are current.
E I – V AMP and F I – V AMP are converted into voltage from the current signal. When correct tracking,
two input (V

3. FOCUS ERROR AMPLIFIER

The focus error amp is the difference between RF I – V AMP (1) output VA and RF I – V AMP (2) output
V

. This two (VA, VB) signals are each applied to the (-) and (+) input of focus error amp. As the result of

B

differential voltage, Focus error signal is appeared at FE1 Pin (Pin57). This FE1 Output Voltage (low
frequency) becomes (A + C) – (B + D), as follow V
The focus error voltage is directed to the focus servo Block, to maintain optimum focusing at all times.

= R1/R3 (VB – VA)

FE1

4. FOCUS OK GENERATION CIRCUIT

The focus OK circuit generates a timing window to monitor focus search status of focus servo. When
RFO (Pin 66) Voltage is more than –0.37V, the focus OK circuit is inverted. Time constant of HPF in EFM
comparator and in mirror circuit and that of LPF in focus OK circuit are determined bu capacitor (0.01µF)
between RFI and RFO.

5. MIRROR CIRCUIT

30

FL8550

After RF input signal is amplified by Mirror amp, it is held in Bottom and Peak hold circuit. Such a hold is
determined by the time constant. Envelope signal A (demodulated to DC) is two-thirds of the peak value
of this signal. The time constant of A signal is held when it is larger than that of B signal. Therefore,
mirror output is; Low at track on disc, High at between tracks on disc, High when defect is detected.

6. DEFECT CIRCUIT

FL8550

31

The bottom hold has had two time constant of long and short, after than the RFI signal inverted. The
short time constant of bottom hold is generated shorter than 0.1m sec of disc mirror defect, and long time
constant is generated by previous mirror level. Mirror defect detection signals are generated by
differentiation on Capacitor Coupling, and then transfer level.

7. EFM COMPARATOR

The EFM Comparator converts a RF signal into a binary signal. A processing of disc production is
occurred disproportion because of modification of disc. That is not reduced by only AC coupling. The
reference voltage of EFM comparator is controlled utilizing the fact that the generation-probability 1, 0 is
50% (duty) in the binary EFM signal.

8. APC (AUTOMATIC POWER CONTROL) CIRCUIT

As the Laser diode has had large negative temperature characteristic when it does something for
regularly supply current on laser diode. Therefore, the output on processing monitor photo diode must be
controlled current for getting regularly output power.

SERVO BLOCK

32

FL8550

1. FOCUS SERVO

When the defect signal is detected, the focus servo Loop is isolated. At this time, the focus servo error
output is outputted through low pass filter formed by connecting a capacitor (0.1µF) between the built-in
470KΩ resistor and FDFCT Pin (Pin58). Accordingly, the focus error output is held as just before error
value during the defect.
The peak frequency of the focus phase compensation is at about 1.2KHz when the resistor connected to
PFSET(Pin7) is 510KΩ. It is inversely proportional to the resistor connected to the Pin 7.

FL8550

33

While the focus search is operating, the FS4 switch is ON and then focus error signal is isolated,
accordingly it is outputted by FSEO Pin (Pin48). When the FS2 switch is ON, the focus servo Loop is on
and then focus error is outputted through the focus servo Loop.

2. TRACKING AND SLED SERVO LOOP

The capacitor across RTG (Pin16) and TGSW (Pin15) reduces high frequency gain when the TG2 switch
is OFF. The Peak frequency of the tracking phase compensation is at about 1.2KHz when the resistor
connected to PFSET (Pin7) is 510KΩ. It is inversely proportional to the resistor connected to the Pin 7.
The tracking error signal is switched into low pass filter route formed by connecting a capacitor between
the built-in resistor at DFCT (470KΩ) and TDFCT (Pin54) as for tracking error signal.

3. SPINDLE SERVO AND LOW PASS FILTER

34

FL8550

The 0.033nF and 20KΩ connected to SMEF (Pin 25) form the 200Hz low Pass filter. And the carrier
component of spindle servo error signals is eliminated. In the CLV – S mode, SMEF becomes L and
Pin25 LPF fc lowers, strengthening the filter further.

PMD-100

PMD-100 Process Decoder

General Description

The PMD-100 HDCD® Process Decoder is a sophisticated

0.6 micron CMOS Integrated Circuit that performs pre­cise decoding of HDCD encoded recordings. The D ecoder
also functions as a state-of-the-art digital filter when fed
data from non-HDCD recordings. It is designed to inter­face directly with popular data receivers and DAC’s, elimi­nates the need for conventional monolithic digital filters.
The PMD-100 has been carefully designed to maximize per­formance and ease of use in a wide variety of applications.

HDCD Process Information

Data encoded with HDCD process information carries pre­cisely encrypted signals, hidden within the LSB of the 16­bit data word. Over time, only 1 to 5% of the LSB is used
for this hidden code. The encoded information is inau­dible and causes no perceptible loss of information. The
PMD-100 recognizes the encrypted signals as HDCD pro­cess information, and directs the decoding function to pre­cisely reconstruct the high resolution signal in a form ap­propriate for output to the D-A converter being used.

Note: To preserve HDCD process information, no alteration
of the encoded data is allowed prior to processing by the PMD-

100. Digital data processing including phase inversion prior to
the PMD-100 input will result in the loss of HDCD process
information encoded in the data.

SPECIAL FEATURES

Automatic HDCD Process Decoding

When the PMD-100 detects HDCD® process infor­mation in the input data, it automatically switches to

®

HDCD
an LED indicator. When non-HDCD
data is received, the decoder automatically operates
as a high performance digital filter.

Excellent Filter Characteristics

When operating as a digital filter, the PMD-100 ex­hibits passband characteristics that have been care­fully optimized to provide extremely accurate sound
quality. Passband ripple from 0 to 20 kHz is within
±.0001 dB and stopband attenuation is greater than
120 dB.

Two Operating Modes

Stand-Alone
In Stand-Alone Mode, the PMD-100 requires no

external controller, allowing for the most cost
effective designs.

Program

In Program mode, an external processor controls
the PMD-100’s many advanced operating modes

and features.

SPECIAL FEATURES (Cont.)

DAC Optimize Operating Modes

To achieve the best possible performance from a variety of
different DAC types, adjustable parameters are provided in­cluding eight different levels of dither and Patented “Silent
Conversion” variable clock timing.

Constant Clock Output

The PMD-100 constantly provides output clocking to the DAC,
even if input data and master clocks are lost. This feature elimi­nates the possiblility of spikes or DC offsets at the DAC’s out­put.
