1 Safety Precautions

PT-52DL10

1.1. General Guidelines

1. It is advisable to insert an isolation transformer in the AC power line before servicing a hot chassis.

2. When servicing, observe the original lead dress, especially the lead dress in the high voltage circuits. If a short circuit is found, replace all parts which have been overheated or damaged by the short circuit.

3. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers, shields, and isolation R-C combinations, are properly installed.

4. Before switching the power on, measure the resistance between B+ line and cold side chassis ground. Connect the “-” side of an ohmmeter to the B+ line, and the “+” side to chassis ground. Each line must have more resistance value than the specified one as follows:

B+ line Minimum Resistance

3.3V (TNPA1743 : L855) 60

12.0V (TNPA1743 : L854) 10k

10.5V (TNPA1744 : L2866) 10k

17.5V (TNPA1745 : L2864) 10k

5. When the set is not used for a long period of time, unplug the AC power cord plug from the AC line outlet.

6. After servicing make the following leakage current checks to prevent the customer from dangerous electrical shock.

1.2. Leakage Current Cold Check

1. Unplug the AC power cord and short between the two prongs of the AC plug with a jumper wire.

2. Set the power switch of this set to ON position.

3. Measure the resistance value with an ohmmeter between the shorted AC plug and each exposed metallic part of the set cabinet such as screwheads, connectors, and control shafts. When the exposed metallic part has a return path to the chassis, the reading should be more than 4 M!.

When the exposed metal part does not have a return path to the chassis, the reading must be infinity.

repaired and rechecked before it is returned to the customer because of a possibility of an electrical shock.

1.4. Hot-Check Circuit

Prepare the measuring circuit as shown in Fig.1.

Be sure to use a voltmeter having the performance described in Table 1.

Fig. 1

Voltmeter (rms reading)

Table 1

Accuracy: 2% Input resistance: Input capacitance: Frequency range: 15Hz to 1MHz

Performance

200pF

1.5. Lamp Precautions

"""" ·""""Be sure to unplug the power cord from the power outlet

when replacing the lamp.

"""" ·""""Because the lamp reaches a very high temperature during

its operation, wait until it cools completely when replacing the lamp.

"""" ·""""The lamp emits small amounts of UV-radiation, avoid

diredt-eye contact with the light.

1.3. Leakage Current Hot Check

(See Fig.1)

1. Plug the AC power cord directly into the AC line outlet. Do not use an isolation transformer for this check.

2. Connect the measuring circuit as shown in Fig.1. between each exposed metallic part of the set and an earth ground such as a water pipe.

3. Use a high impedance AC voltage meter to measure the voltage across the resistor.

4. Measure the voltage at each exposed metallic part.

5. Reverse the AC plug inserting direction at the AC line outlet and repeat each of the above measurements.

6. The voltage at any point must be less than 0.25Vrms.

7. A leakage current tester (SIMPSON MODEL 228 or the equivalent) may be used to make the hot checks. In this case, the current must be less than 500µA.

8. If the reading is more than the above value, the set must be

PT-52DL10

2 Functions for Safety

2.1. Temperature Detection for the Lamp Unit

This projector has the bimetal contacting the lamp unit to project the lamp. If the temperature of the lamp unit exceeds 100°C, the bimetal will operate to turn off the power.

The installed position of the bimetal is shown in the illustration.

To recover the bimetal from its off state, press the protrusion of the bimetal unit you hear it click.

2.2. Interlock Switch

To ensure safety, this projection TV is designed so that the power cannot be turned on without the Lamp Unit Cover or under its imperfect installation.

If removing the Lamp Unit Cover during the operation of the Projection TV, the power will be turned off.

3 Customer Operation

Turning the Power ON and OFF

Always be sure to follow the procedure given below to turn the projection TV power ON and OFF.

The lamp cooling fan will continue to operate for approximately 90 seconds after the power is turned off by the remote control.

•

At the same time, the power indicator will blink Orange. Normally, use the remote control to turn the power OFF (turning the picture OFF).

Do not disconnect the power cord from the power outlet or do not open any circuit breakers while the cooling fan is still operating. Do not disconnect the power cord from the power outlet while in Stand-by mode.

When you want to turn on the power again immediately after turning off the power during the operation of the projection

•

TV, be sure to wait until the cooling fan stops and then turn on the power. Setting the projection TV to Stand-by, the power indicator will light up red.

Push the Pow er switch on the projection TV to turn the power on.

The Power Indicator will become Green and blink (approximately 10 seconds).

Notes:

(1) The PC input terminals are DDC1/2B-compatible. If the computer being connected is not DDC1/2B-compatible, you will

need to make setting changes at the computer at the time of connection. (2) Some PC models cannot be connected to the set. (3) An adapter is required to use the PC cable (D-SUB 15P) to connect a Macintosh computer to the set. (4) There is no need to use an adapter for computers with PC / AT compatible D-SUB 15P terminal. (5) The computer shown in the illustration is for example purposes only. (6) Additional equipment and cables shown are not supplied with this set. (7) The picture will become dark if a PC signal with a vertical scanning frequency of 62 Hz is input. To obtain the optimum

picture quality with the projection TV, a vertical scanning frequency of 60 Hz is recommended. (8) Do not set the horizontal and vertical scanning frequencies for PC signals which are above or below the specified

frequency range.

4 New functions on this projector

4.1. DLP™ Projector

The DLP™ projector employs a newly developed component called the DMD™ element. This element is made up of extremely small mirrors (13 microns square) arrayed on a silicon board. By digitally controlling the element, the projector controls the direction that light is reflected off its mirrors, focusing the reflected light using a prism and composing an image on the screen using a lens. Fig.2 shows the optic system of a DLP™ projector equipped with one DMD™ element.

4.2. DMD™ element structure

In a DMD™, from 100,000 to 1 million mirrors 13 microns square (DMD™ elements) are arrayed as shown in Fig. 3.

A single DMD™ element (single mirror) forms one picture element (pixel). Each DMD™ element is constructed as shown in Fig. 4 at right. The micromirror is supported by a central support post, and the post rides on panel called a yoke.

The CMOS memory element directly below the micromirror corresponding to each image pixel inclines the micromirror by ± 10°.

For example, if the CMOS memory element output is given the instruction Q:1, Q is charged with static electricity, tilting so that the 2 ends supported by the support from a diagonal line center. Conversely, if A:0, corresponding to [ speed, the time required for a change of direction is about 10 microseconds.

:0, then the side of the yoke corresponding to

:1 is the instruction, the side

] tilts. Because the unit operates at high

In this way, the micromirror parallel to the yoke is operated by binary control (PWM modulation) corresponding to “1” or “0”.

4.3. DMD™ element operation

As described earlier, in DMD™ operation, a single image is formed by digitally controlling the light reflected from the element surface (light modulation) by switching the device on (light reflected by micromirror is projected on the screen) or off (no projection) and by bringing each micromirror into position with each pixel.

As shown in Fig. 5, light is projected onto the DMD™ element at an angle 20° from horizontal. If the DMD™ element is OFF, the light reflected by the micromirror (A) does not enter projection lens, and the matching point on the screen appears black. If the DMD™ element is ON, the light reflected by the micromirror passes through the projection lens and is projected brightly on the screen. By adjusting the length of time for micromirror reflection, ti is possible to create 256 gradations for each color; as a result,

1.67 million colors can be formed by combining the 3 colors.
