Note:
 Refer to the “5. TEST MODE” (page 23) for another self-diagnosis
function.
Self-diagnosis Function 
(When letters/numbers appear in the 
display)
When the self-diagnosis function is activated 
to prevent the player from malfunctioning, a 
five-character service number (e.g., C 13 50) 
with a combination of a letter and four digits 
appears on the screen and the front panel 
display. In this case, check the following 
table.

have checked the inside 
of the rotary table and 
resolved any possible 
problems, press H.

CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous ra-
diation exposure.
Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270 ˚C dur-
ing repairing.
• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
• Be careful not to apply force on the conductor when soldering
or unsoldering.
SAFETY  CHECK-OUT
After correcting the original service problem, perform the follow-
ing safety check before releasing the set to the customer:
Check the antenna terminals, metal trim, “metallized” knobs,
screws, and all other exposed metal parts for AC leakage.
Check leakage as described below.
LEAKAGE  TEST
The AC 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 microamperes.).
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-operated AC 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 pas-
sive VOM that is suitable. Nearly all battery operated digital
multimeters that have a 2 V AC range are suitable.  (See Fig. A)

UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the lead-
free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size)
: LEAD FREE MARK
Unleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40 ˚C higher than
ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350 ˚C.
Caution: The printed pattern (copper foil) may peel away if the
heated tip is applied for too long, so be careful!
• Strong viscosity
Unleaded solder is more viscou-s (sticky, less prone to flow)
than ordinary solder so use caution not to let solder bridges oc-
cur such as on IC pins, etc.
• Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.

This Player Can Play the 
Following Discs
“DVD VIDEO” and “DVD-RW” are 
trademarks.
Region code
Your player has a region code printed on the 
back of the unit and will only play DVD 
VIDEOs (playback only) labeled with 
identical region codes. This system is used to 
protect copyrights.
DVD VIDEOs labeled 
 will also play on 
this player.
If you try to play any other DVD VIDEO, the 
message “Playback prohibited by area 
limitations.” will appear on the TV screen. 
Depending on the DVD VIDEO, no region 
code indication may be labeled even though 
playing the DVD VIDEO is prohibited by 
area restrictions.

Notes
• Note about DVD-RWs/DVD-Rs, DVD+RWs/
DVD+Rs, or CD-Rs/CD-RWs.
Some DVD-RWs/DVD-Rs, DVD+RWs/
DVD+Rs, or CD-Rs/CD-RWs cannot be played 
on this player due to the recording quality or 
physical condition of the disc, or the 
characteristics of the recording device and 
authoring software. Also, images in DVD-RWs  
with CPRM* protection may not be played if they 
contain a copy protection signal. “Copyright 
lock” appears on the screen. For more 
information, see the operating instructions for the 
recording device.
Note that discs created in the Packet Write format 
cannot be played.
* CPRM  (Content Protection for Recordable 
Media) is a coding technology that protects 
copyright for images.
• Music discs encoded with copyright protection 
technologies
This product is designed to playback discs that 
conform to the Compact Disc (CD) standard. 
Recently, various music discs encoded with 
copyright protection technologies are marketed 
by some record companies. Please be aware that 
among those discs, there are some that do not 
conform to the CD standard and may not be 
playable by this product. 
Note on playback operations of 
DVDs and VIDEO CDs
Some playback operations of DVDs and 
VIDEO CDs may be intentionally set by 
software producers. Since this player plays 
DVDs and VIDEO CDs according to the disc 
contents the software producers designed, 
some playback features may not be available. 
Also, refer to the instructions supplied with 
the DVDs or VIDEO CDs.
