SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer:
1. Check the area of your repair for unsoldered or poorly-soldered connections. Check the entire board surface for solder
splashes and bridges.
2. Check the interboard wiring to ensure that no wires are
“pinched” or contact high-wattage resistors.
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.
3. Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair. Point them
out to the customer and recommend their replacement.
1. A commercial leakage tester, such as the Simpson 229 or RCA
WT-540A. Follow the manufacturers' instructions to use these
instruments.
4. Look for parts which, though functioning, show obvious signs
of deterioration. Point them out to the customer and recommend their replacement.
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 0.75V, so analog meters must have an accurate lowvoltage 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 2V AC range are suitable. (See Fig. A)
5. Check the line cord for cracks and abrasion. Recommend the
replacement of any such line cord to the customer.
6. Check the B+ voltage to see it is at the values specified.
7. Check the antenna terminals, metal trim, “metallized” knobs,
screws, and all other exposed metal parts for AC leakage.
Check leakage as described below.

Recording and Tape Speed Buttons
You can use this VCR to record images input through the LINE IN jacks. For example, let’s say you
want to record images of your child that you took with your video camera.
1
Press the SP/EP button to set the tape speed.
EP (Extended Play) provides recording time three times as long as SP (Standard Play).
However, SP produces better picture and audio quality.

4
Connect your video camera’s LINE OUT jacks to the LINE IN jacks on the back of this
VCR, and insert a blank tape with its safety tab intact into this VCR. (If you are recording
a program on your TV, be sure to disconnect the VCR’s LINE OUT jacks from your TV’s
LINE IN jack and set the TV’s TV/VIDEO button to TV.)
Press the z REC (record) button on this VCR.
Start playing the tape in your video camera.
The REC mark and tape speed (EP or SP) appear on your TV screen. To stop recording,
press x STOP.
Note
• The z REC button will not function when the Play Timer is activated. Cancel the Play Timer before you make a
recording.

Step 1
Using the supplied audio/video cable, connect one of the yellow plugs to VIDEO of LINE OUT on
this VCR, and the other yellow plug to VIDEO of LINE IN on your TV.
Step 2
Connect both of the red and white plugs, in any order, to the black AUDIO LINE OUT jacks on this
VCR, and the other ends to the AUDIO LINE IN jacks on your TV. If your TV is monaural (only one
AUDIO LINE IN jack), you only need to use one of the red or white plugs. Just be sure to connect
the same color plug to both the VCR and your TV.
Step 3
Plug in the power cord to an AC outlet.
Note
• If your TV only has an RF jack (antenna jack), you need to use an RF modulator (not supplied) to connect this VCR.
Refer to your modulator’s instruction manual for further details.

cable VMC-910MS (sold separately). Play the original tape on
the other video source and use this VCR to make the
recording. See “ Recording and Tape Speed Buttons” on the reverse for more information.
Note
• If you connect your TV’s LINE OUT jacks to the LINE IN jacks, be sure to disconnect the VCR’s LINE OUT jacks
from your TV’s LINE IN jacks.

SECTION 4
PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
For schematic Diagram:
• Caution when replacing chip parts.
New parts must be attached after removal of chip.
Be careful not to heat the minus side of tantalum capacitor,
because it is damaged by the heat.
• All resistors are in ohms, 1/4 W (Chip resistors : 1/10 W) unless otherwise specified.
kΩ : 1000Ω, MΩ : 1000kΩ.
• All capacitors are in µF unless otherwise noted. pF : µµF
50V or less are not indicated except for electrolytics and
tantalums.
• All variable and adjustable resistors have characteristic curve
B, unless otherwise noted.
• 2 : nonflammable resistor.
• 5 : fusible resistor.
• C : panel designation.
•
f
: internal component.
• U : B+ Line.
• V : B– Line.
• Circled numbers refer to waveforms.
• Voltages are dc between measurement point.
• Readings are taken with a color-bar signal input.
• Readings are taken with a digital multimeter (DC 10MW).
• Voltage variations may be noted due to normal production
tolerances.
THIS NOTE IS COMMON FOR PRINTED WIRING
BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed
in each block.)
For printed wiring board:
• X : indicates a lead wire mounted on the component
side.
• x : indicates a lead wire mounted on the printed side.
• b : Pattern from the side which enables seeing.
(The other layers’ patterns are not indicated.)
Note:
The components identified by mark 0 or dotted
line with mark 0 are critical for safety.
Replace only with part
number specified.
Note:
Les composants identifiés par
une marque 0 sont critiques
pour la sécurité.
Ne les remplacer que par une
pièce portant le numéro
spécifié.
When indicating parts by reference
number, please include the board
name.

ADJUSTMENTS
2-1-3. Set-up of Adjustment
In this adjustment, NTSC pattern generator is connected with LINE
input signal terminal. When check to tuner, connected AERIAL
terminal. Check that the amplitudes of video signal SYNC signal,
of picture portions, and of burst signals are flat at approximately
0.3, 0.7 and 0.3 V, respectively, and that the level ratio of the burst
signal and “red” signal are 0.30: 0.66. Fig. 6-2-2. shows video signals
(color bars) used in adjusting the video section.
During the adjustment, see the Parts Arrangement
