Important Safety Precautions

Connector
Metal sleeve
Prior to shipment from the factory, JVC products are strictly inspected to conform with the recognized product safety and electrical codes of the countries in which they are to be sold. However, in order to maintain such compliance, it is equally important to implement the following precautions when a set is being serviced.
v
Precautions during Servicing
1. Locations requiring special caution are denoted by labels and inscriptions on the cabinet, chassis and certain parts of the product. When performing service, be sure to read and com­ply with these and other cautionary notices appearing in the operation and service manuals.
2. Parts identified by the symbol and shaded ( ) parts are critical for safety. Replace only with specified part numbers.
Note: Parts in this category also include those specified to com-
ply with X-ray emission standards for products using cathode ray tubes and those specified for compliance with various regulations regarding spurious radiation emission.
3. Fuse replacement caution notice. Caution for continued protection against fire hazard. Replace only with same type and rated fuse(s) as specified.
4. Use specified internal wiring. Note especially:
1) Wires covered with PVC tubing
2) Double insulated wires
3) High voltage leads
5. Use specified insulating materials for hazardous live parts. Note especially:
1) Insulation Tape 3) Spacers 5) Barrier
2) PVC tubing 4) Insulation sheets for transistors
6. When replacing AC primary side components (transformers, power cords, noise blocking capacitors, etc.) wrap ends of wires securely about the terminals before soldering.
12. Crimp type wire connector In such cases as when replacing the power transformer in sets where the connections between the power cord and power transformer primary lead wires are performed using crimp type connectors, if replacing the connectors is unavoidable, in or­der to prevent safety hazards, perform carefully and precisely according to the following steps.
1) Connector part number : E03830-001
2) Required tool : Connector crimping tool of the proper type
which will not damage insulated parts.
3) Replacement procedure
(1) Remove the old connector by cutting the wires at a point
close to the connector. Important : Do not reuse a connector (discard it).
cut close to connector
Fig.3
(2) Strip about 15 mm of the insulation from the ends of
the wires. If the wires are stranded, twist the strands to avoid frayed conductors.
15 mm
7. Observe that wires do not contact heat producing parts
8. Check that replaced wires do not contact sharp edged or
9. When a power cord has been replaced, check that 10-15 kg of

force in any direction will not loosen it.
Power cord
Fig.2
In regard to such products, the cathode ray tubes themselves, the high voltage circuits, and related circuits are specified for compliance with recognized codes pertaining to X-ray emission. Consequently, when servicing these products, replace the cath­ode ray tubes and other parts with only the specified parts. Under no circumstances attempt to modify these circuits. Unauthorized modification can increase the high voltage value and cause X-ray emission from the cathode ray tube.
Fig.4
(3) Align the lengths of the wires to be connected. Insert
the wires fully into the connector.

(4) As shown in Fig.6, use the crimping tool to crimp the
metal sleeve at the center position. Be sure to crimp fully to the complete closure of the tool.

Safety Check after Servicing
Examine the area surrounding the repaired location for damage or deterioration. Observe that screws, parts and wires have been returned to original positions, Afterwards, perform the following tests and confirm the specified values in order to verify compli­ance with safety standards.
1. Insulation resistance test
Confirm the specified insulation resistance or greater between power cord plug prongs and externally exposed parts of the set (RF terminals, antenna terminals, video and audio input and output terminals, microphone jacks, earphone jacks, etc.). See table 1 below.
2. Dielectric strength test
Confirm specified dielectric strength or greater between power cord plug prongs and exposed accessible parts of the set (RF terminals, antenna terminals, video and audio input and output terminals, microphone jacks, earphone jacks, etc.). See table 1 below.
3. Clearance distance
When replacing primary circuit components, confirm specified clearance distance (d), (d’) be­tween soldered terminals, and between terminals and surrounding metallic parts. See table 1 below.
Chassis
Fig. 8
4. Leakage current test
Confirm specified or lower leakage current between earth ground/power cord plug prongs and externally exposed accessible parts (RF terminals, antenna terminals, video and audio input and output terminals, microphone jacks, earphone jacks, etc.). Measuring Method : (Power ON) Insert load Z between earth ground/power cord plug prongs and externally exposed accessi­ble parts. Use an AC voltmeter to measure across both terminals of load Z. See figure 9 and following table 2.
5. Grounding (Class 1 model only)
Confirm specified or lower grounding impedance between earth pin in AC inlet and externally exposed accessible parts (Video in, Video out, Audio in, Audio out or Fixing screw etc.).
Measuring Method:
Connect milli ohm meter between earth pin in AC inlet and exposed accessible parts. See figure 10 and grounding specifications.

In case that defective EEPROM of PAL models is replaced, to operate these sets from the initial state MP KEY must be repaired as well before delivering to the customer. If MP KEY isn’t repaired the setting of RF OUT channel or LANGUAGE might be different from that for cus­tormer’s country.
•MP KEY : In case of PALVCR if holding the REC button on the front panel and the CLEAR button on the remote control handset for 5 ~ 7 seconds with power being switch all and no tapes, OK is displayed at FLD for FLD models and LED becomes on for LED CLOCK models. This is the state that initializing EEPROM is finished. (In case of PAL VCP if holding the REC button on the front panel and the MENU button on the remote control handset for 5 ~ 7 seconds with power being off and no tapes, All the LED DOTs become on. This is the state that initializing EEPROM is finished.)

1. DETECT NEW EEPROM (OPTION EDIT SCREEN)
- Eeprom EDIT screen automatically appears if replacing Eeprom.
• Setup option data using the cursor Up/Down key of a remote control. (Setup upon BOM depending on OPT1~OPT6 model)
• Since an initial remote control is set to LG for LG model, appro­priately set optional data using the cursor Up/Down key.
2. EEPROM WRITED COMPLETE SCREEN
- Writes data on EEPROM by using REMOCON "OK".
- If completing the option data screen with a menu key, Powering Off is automatically done and the option edit screen is arranged.
3. PG ADJUST a) Insert the PALSP Test Tape and play.
Note - Adjust the distance of X, pressing the Tracking(+) or
Tracking(-) when the “ATR” is blink after the PAL SP Test Tape is inserted.
b) Press the Auto PG KEY on JIG Remocon(1’st) or Press “REC”
key on set and “CLEAR” key on Remocon.(Then check the blink “TRK OK” on CLK/LED-TRK is a Initial)
c) Press the Auto PG Key on JIG Remocon again (2’nd) or press
“REC” key on set and “CLEAR” key on Remocon again.(Then check the blink “PG NG > PG OK” on CLK/LED.)
4. EEPROM INITIAL
- SETUP is displayed in the field if pressing the FRONT REC KEY
with the remocon number "CLEAR" key pressed in the status of powering Off.
- AUTO SEARCH is done since the initial screen of ACMS is ser-
viced if powering On.
- Check basic operation (PLAY/RECORD...)

• Adjustment Procedure
a) Insert the PAL SP Test Tape and play.
Note - Adjust the distance of X, pressing the Tracking(+) or Tracking(-) when the “ATR” is blink after the
PAL SP Test Tape is inserted.
b) Press the Auto PG KEY on JIG Remocon(1’st) or Press “REC” key on set and “CLEAR” key on
Remocon.(Then check the blink “TRK OK” on CLK/LED-TRK is a Initial)
c) Press the Auto PG Key on JIG Remocon again (2’nd) or press “REC” key on set and “CLEAR” key on
Remocon again.(Then check the blink “PG NG > PG OK” on CLK/LED.)
• Check the PG
a) Connect the CH1 of the oscilloscope to the H/SW and CH2 to the Video out for the VCR. b) Trigger the mixed Video Signal of CH2 to the CH1 H/SW(W501, W502), and then check the distance
(time difference), which is from the selected A(B) Head point of the H/SW(W501, W502) signal to the starting point of the vertical synchronized signal, to 6.5H ± 0.5H (416µs, 1H=64.0µs).
