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.

•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.

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.

DISASSEMBLY

1.1 BEFORE ASSEMBLY AND DISASSEMBLY

1.1.1 Precautions

1.Be sure to remove the power supply unit prior to mounting and soldering of parts.

2.When removing a component part that needs to disconnect the connector and to remove the screw for removing itself, first disconnect the connecting wire from the connector and then remove the screw beforehand.

3.When connecting and disconnecting the connectors, be careful not to damage the wire.

4.Carefully remove and handle the part to which some spacer or shield is attached for reinforcement or insulation.

5.When replacing chip parts (especially IC parts), desolder completely first (to prevent peeling of the pattern).

6.Tighten screws properly during the procedures. Unless specified otherwise, tighten screws at a torque of 0.088N•m(0.9kgf•cm).

1.4 4 MONITOR ASSEMBLY

Note: The shape of the monitor assembly varies by the size of the LCD screen.

For the 2.5”-type LCD, refer to Fig. 1-4-1.

1.4.1Disassembly/assembly of monitor assembly (for 2.5”-type LCD)

Note: Be careful not to soil or scratch the monitor screen through the disassembly/assembly work.

1.Remove the four screws 1 to 4 in numerical order. While disengaging the six hooks (L4a to L4f) in alphabetical order, remove the monitor cover assembly.

2.Unlock the connector a and then disconnect the FPC while lifting the hinge assembly upwards to remove it together with the FPC.

Note4a: For disconnecting the FPC, unlock the connector first and then lift the hinge assembly upwards. Accordingly, the FPC is disconnected together with the hinge assembly.

Note4b: Treat the wires carefully.

3.Unplug the wires and FPCs from the two connectors b , c , and then remove the MONITOR BL board assembly, holder (PWB) and backlight in that order.

4.Remove the LCD module.

1.4.2Disassembly/assembly of hinge assembly (for 2.5”-type LCD)

1.Remove the three screws (5 to 7), and then remove the hinge covers (1) and (2) by disengaging a total of four hooks (L4g, L4h) at the two sides.

2.Separate the SW board assembly and the FPC from the hinge assembly.

Note4c: When connecting the FPC, arrange the FPC wire by winding it around the shaft (hinge pin) of the hinge assembly by two and a half turns while paying heed to the orientation of the hinge assembly and FPC.

Note4d: When disassembling/assembling the hinge assembly, pay careful attention to every part not to damage anything.

Note: Be careful not to soil or scratch the monitor screen through the disassembly/assembly work.

1.Remove the four screws 1 to 4 in numerical order. While disengaging the six hooks (L4a to L4f) in alphabetical order, remove the monitor cover assembly.

3.Unplug the wires and FPCs from the two connectors b , c , and then remove the MONITOR BL board assembly, holder (PWB) and backlight in that order.

4.Remove the LCD module while disengaging it from the four hooks (L4g, L4h, L4j, L4k,).

1.4.4Disassembly/assembly of hinge assembly (for 3.5”-type LCD)

1.Remove the three screws (5 to 7), and then remove the hinge covers (1) and (2) by disengaging a total of four hooks (L4m, L4n) at the two sides.

2.Separate the SW board assembly and the FPC from the hinge assembly.

2.Unlock the connector a and then disconnect the FPC while lifting the hinge assembly upwards to remove it together with the FPC.

Note4f: For disconnecting the FPC, unlock the connector first and then lift the hinge assembly upwards. Accordingly, the FPC is disconnected together with the hinge assembly.

Note4g: Treat the wires carefully.

Note4h: When disassembling/assembling the hinge assembly, pay careful attention to every part not to damage anything.

Note4j: When connecting the FPC, arrange the FPC wire by winding it around the shaft (hinge pin) of the hinge assembly by two and a half turns while paying heed to the orientation of the hinge assembly and FPC.
