JVC HR-V200EZ, HR-V205EK, HR-V500EZ, HR-V505EK, HR-V505EZ Service Manual

Important Safety Precautions

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 comply 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.

Fig.1

7.Observe that wires do not contact heat producing parts (heatsinks, oxide metal film resistors, fusible resistors, etc.)

8.Check that replaced wires do not contact sharp edged or pointed parts.

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

10.Also check areas surrounding repaired locations.

11.Products using cathode ray tubes (CRTs)

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.

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

Fig.4

(3)Align the lengths of the wires to be connected. Insert the wires fully into the connector.

v 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.

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.

PROPOSAL FOR APPLYING SHORT PROTECTION

• The Contents of Examination

As all the IC that is applied to VCR is controlled by IIC, mutual communication, if Vcc of IC is short or open with detecting ‘Acknowledge’ data of the specific IC according to each power(5V, 5VT) -COM gets unable to detect ‘ACK’ data.

-COM regards this case as abnormal one and if it can’t detect ‘ACK’ data for a certain time(3.5 sec) the signal of ‘Power Control’ and ‘Timer Control’ are switched to ‘Low’. As a result POWER SwitchingTR is kept from generating heat and fire.

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 PAL VCR 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.)

•MP KEY's function: MP KEY sets EEPROM's data up to the initial state.

EEPROM option code No. setting procedure

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 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.)

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 serviced if powering On.

-Check basic operation (PLAY/RECORD...)
