SAFETY CHECK-OUT
(US model only)
After correcting the original service problem, perform the
following safety checks before releasing the set to the customer:
Check the antenna terminals, metal trim, “metallized” knobs, screws,
and all other exposed metal parts forAC leakage. Check leakage as
described below.
LEAKAGE
TheAC leakage from any exposed metal part to earth ground and
from all exposed metal parts to any exposed metal part having a
return to chassis, must not exceed 0.5 mA (500 microampers).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA
WT-540A. Follow the manufacturers’instructions to use these
instruments.
2. A battery-operated AC milliammeter. The Data Precision 245
digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a
VOM or battery-operatedAC voltmeter. The “limit” indication
is 0.75 V, so analog meters must have an accurate low-voltage
scale. The Simpson 250 and Sanwa SH-63Trd are examples of
a passive VOM that is suitable. Nearly all battery operated
digital multimeters that have a 2VAC range are suitable. (See
Fig. A)
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic
breakdown because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic breakdown and also use
the procedure in the printed matter which is included in the repair
parts.
The flexible board is easily damaged and should be handled with
care.
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused on
the disc reflective surface by the objective lens in the optical pick-
up block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.

SECTION 3
TEST MODE
1ADJ Mode
When the main power is turned on while the ADJ terminal is set to
LOW, the CDP-C591/CE235/335 enters theADJ mode that enables
to implement the servo related checks.
The disk tray is not loaded or rotated.
The fifth program is automatically played back.
The following items are valid even when the main power is turned
on first and the ADJ terminal is then set to LOW.
The high speed search cannot be performed.
The focus servo gain is not decreased.
CLV servo gain is not decreased.
GFS is ignored even if it is set to the LOW.
Q data is ignored even if it cannot be read.
Switching of the monitor terminal is possible.
Every pressing of the FADER key advances the MONITOR
terminal in the following order.
RFCKnGFCnError rate
When “3” of the remote controller is pressed, the tracking servo
is turned off.
When “8” of the remote controller is pressed, the tracking servo
is turned on.
* The servo related items cannot be checked in the CDP-C591/
CE235/335.
2Key Check and Display Check Mode
When the main power is turned on while the AFADJ terminal is set
toLOW, the CDP-C591/CE235/335 enters the keycheck and display
check mode in which keys and displays can be checked.
First, all display tubes turn on.
When any key is pressed after display tubes are turned on, the
number of the keys that have been pressed appear on the left
and the key number appears on the right.
(Pushing the JOG key is counted as one of the keys.)
However, the following keys are treated as the special keys
that show the different operations.
STOP : All display turn-on check
PLAY : Grid check
PAUSE : Segment check
JOG : Calendar check
When receiving a signal from remote controller, the display
“ []– ** ” appears.
(Number of asterisks ** changes depending on the pressed
key. For example, ** is 50 when the PLAY key is pressed.)
3Default Shipment Mode
When the main power is turned on while pressing the DISCSKIP
and the PROGRAM keys, the CDP-C591/CE235/335 enters the
default shipment mode in which the default settings when shipped
from the factory are set.
Move the DISC 1 to the front and stop the machine. When the
message “NODISC” appears, it indicates that the mode has
ended with success.
4Aging Mode
When the OPEN key is pressed while the DISC1 and the CHECK
keys are being pressed with the main power being turned ON, the
CDP-C591/CE235/335 enters the aging mode in which aging is
performed in the following sequence.
Reads TOC A-1
Accesses the last program A-2
Plays the last program for 3 seconds PLAY display appears
EX-CHANGE A-4
DISCSKIP A-5
CLOSE A-6
Accesses the first program A-7
Playback the first program PLAY display appears
OPEN A-9
DISPSKIP A-A
CLOSE A-0
Whenanerroroccursduringaging,themessage“Err–*”appears
and the operation is stopped.
The system does not accept any key operations during aging.

E-F Balance (1Track jump) Check
Procedure :
1. Connect oscilloscope to TP (TE) andTP (VC).
2. Turned Power switch on.
3. Load a disc (YEDS-18) and playback the number five track.
4. Press the (button. (Becomes the 1 track jump mode.)
5. Confirmthatthelevel B andA (DC voltage) on the oscilloscope
waveform.
Note :
1. CD Block is basically designed to operate without adjustment.
Therefore, check each item in order given.
2. UseYEDS-18 disc (3-702-101-01) unless otherwise indicated.
3. Use an oscilloscope with more than 10MΩimpedance.
4. Clean the object lens by an applicator with neutral detergent
when the signal level is low than specified value with the
following checks.
S-Curve Check
Procedure :
1. Connect oscilloscope to TP (FE).
2. Connect between TP (FE1) and TP (VC) by lead wire.
3. Connect betweenTP (AGCCON) and TP (GND) by lead wire.
4. Turn Power switch on.
5. Load a disc (YEDS-18) and actuate the focus search. (In
consequence of open and close the disc tray, actuate the focus
search)
6. Confirm that the oscilloscope waveform (S-curve) is
symmetrical between A and B. And confirm peak to peak level
within 4 ±1 Vp-p.
7. After check, remove the lead wire connected in step 2 and 3.
Note : • Try to measure several times to make sure than the ratio
of A : B or B :A is more than 10 : 7.
• Take sweep time as long as possible and light up the
brightness to obtain best waveform.
