SECTION 1 PRECAUTION

1.1SAFTY 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.

1.1.1 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-rayemission 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:

Wires covered with PVC tubing

Double insulated wires

High voltage leads

(5)Use specified insulating materials for hazardous live parts. Note especially:

Insulation Tape

PVC tubing

Spacers

Insulation sheets for transistors

Barrier

(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.1-1-1

(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 10-15kg of force in any direction will not loosen it.

Power cord

Fig.1-1-2

(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-rayemission.

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-rayemission from the cathode ray tube.

(12)Crimp type wire connectorIn such cases as when replacing the power transformer in sets where the connections between the power cord and power trans former 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.

Connector part number :E03830-001

Required tool : Connector crimping tool of the proper type which will not damage insulated parts.

Replacement procedure

a)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.1-1-3

b)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.1-1-4

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

1.1.2 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 Fig.1-1-11below.

(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 Fig.1-1-11below.

(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 Fig.1-1-9and followingFig.1-1-12.

1.1.4 Additional cautionary items

High voltage is applied for lighting the lamp. During adjustments and other work with the cover removed, extreme care is needed to avoid electric shock.

Use care to avoid touching the fan or safety switch terminals during work with the cover removed.

Select a stable, horizontal work site to prevent dropping the product and components.

Use the power cord and interface cable supplied with the product.

Before starting work, be sure to also check the safety notices contained in the instruction manual.

1.2INSTALLATIONS

1.2.1 Installation method

The D-ILAsystem (reflecting type active matrix liquid crystal system) does not require convergence adjustment. Note the following when placed on a floor (refer to OPERATING INSTRUCTIONS for actual operating method).

(1)Place the projector at the position needed for the required image size observe the projector is not tilted horizontally.

[The image size is 40 to 200(wide side) inches diagonal (16:9), requiring a projection distance of 1.58m to 8.03m (wide side).]

(2)Adjust the placement site and screen tilt so that the projection angle is perpendicular to the screen.

(3)Adjust the placement site and screen position (height) so that the projection lens center is at the lower edge of the screen.

(4)Project an image on the screen. (Connect video equipment and power source, switch power on and select the input.)

(5)Fine adjust the projected image position and angle. If adjusting the placement site and screen cannot correct the projected position (too low) or angle (lower part of image widened), adjust the front foot.

(6)Turn the lens ZOOM ring by hand and adjust for suitable image size.

(7)Turn the lens FOCUS ring by hand and adjust to correct image blur.

1.2.2 Installation site and status

The projector contains a fan for cooling. Obstruction of the ventilation openings can lead to internal overheating, abnormal operation and failure. Also observe there is plenty of free space between the projector and adjacent walls, ceiling and other equipment. Note that excess heat can cause failure and damage to both the projector and nearby equipment.

Required spacing :

Front = 15cm / left and right sides = 30cm / rear = 50cm (When the unit is enclosed with block according to the required spacing on the left side, provide the unit with adequate ventilation so that the temperature inside of the enclosed area is kept at the same temperature in the open space in the room.)

Avoid locations that are wobbly or inclined. If the setting site floor has protrusions or horizontal cannot be maintained, there is risk the projector may drop, fall over, etc. If located in a site where left to right tilt is greater than ±5° and front to rear tilt greater than ±20°, particularly the optical system components can be severely affected and there is risk basic performance and quality of the projector cannot be maintained.

Observe the site can stably bear the weight (approx. 6.2kg) of the projector over a long period of time.

If mounted on a stand with casters, observe the casters are securely braked to prevent movement.

Avoid suspending in a location subject to vibration. Both the projector and mounting fixture can be damaged.

Do not place in the following types of locations.

Especially, Avoid locations subject to dust, grit, smoke or other airborne contaminants. Use adequate caution when providing external ventilation, filters and dust protection.

Near water or in humid sites Near heaters or heat generating equipmentDust or grit Direct sunlight

Oily or tobacco smokes Very high or very low temperature
