Chapter 2 Theory of Operation
EMP-S3 2.1 Hardware Overview The hardware for the EMP-S3 can basically be divided into two sections: the optical engine and the circuit system. This section of the manual describes functions of the major hardware components. The components and unit in the dotted frame shown in the diagram below make up an optical engine and MA Board Kit, which is provided as one part. *1: The Intake Fan cools the R, G and B light valves (LCD panels).
EMP-S3 2.1.1 Component Connection Diagram The connectors for the components and Main (MA) board are shown in the following diagram. Figure 2-2.

EMP-S3 2.2 Optical Engine The optical system consists of four components: the Lamp Assys., the Light Guide Unit, the Panel-on-Prism (POP) Unit, and the projection lens. These four components together are called the Optical Engine. Projection lens (focus) Light Valve (B) POP Unit Light Valve (R) Light Valve (G) Light Guide Unit Figure 2-4. Optical Engine Optical Engine Figure 2-5.
EMP-S3 C H E C K P O IN T The Lamp Assy., Light Guide Unit, POP Unit, and Projection Lens together make up the Optical Engine. These components are assembled and adjusted together at the factory, and are not available as separate service parts. C A U T IO N Do not subject the optical system components to physical shocks or strong vibration. Do not disassemble the Light Guide Unit. Disassembly will cause color distortion, even if reassembled very carefully.
EMP-S3 2.2.1 Lamp Assy. The Lamp Assy. is comprised of the Lamp (UHE-135W) and Ballast Power Supply Connector. The Ballast Power Supply Connector is used to supply the AC voltage from the ballast unit for driving the lamp. The lead wires are connected to the lamp. The lamp is fastened to the bottom of the projector body with 2 screws. The lamp is a consumable part, and is to be replaced as the luminance of the Lamp Assy. declines over time as the lamp is used.
EMP-S3 2.3 MA Board The MA board processes the core circuit controls for the projector, including interface control, operation panel control, temperature sensor circuit and fan control, ballast power supply control and the Infrared RC board interface. The MA board also contains an imaging processor (PW465), EEPROM, digitizers (ADC and video decoder), and SRAM memory. 2.3.1 External View of MA Board Figure 2-8. MA Board Top Figure 2-9.
EMP-S3 2.3.2 Overview of Operation Digitalization control of the picture signal Converts the analog RGB image signals input from Computer/Component Video port from analog to digital form. Frequency transformation control Transforms the picture signal into the appropriate signals to drive the R, G and B LCD panels. On screen display Displays the menu and other information overlaid onto the input picture signal.
EMP-S3 2.4 Interface Connectors The MA board includes interface connectors for external devices such as video equipment. The MA board is equipped with the following connectors. Computer port USB port S-Video port Remote control light-receiving area Monitor Out port Video port Audio input Figure 2-10.
EMP-S3 2.5 Power Supply Ballast Unit The Power Supply Ballast Unit contains the power supply/ballast section, power supply filter and the AC cord socket. The power supply/ballast section re-regulates the DC power supply that comes from the AC inlet and power supply filter in order to generate the AC power supply 135W for the UHE lamps. AC Inlet Figure 2-12. Power Supply Ballast Unit 2.5.
EMP-S3 2.5.2 Overview of Operation The output cable of the power supply unit is connected to CN2000 on the MA board. It allows the following voltages and signals to be transmitted. • DC output • The power supply On/Off signal (PWON) C A U T IO N Background power is still supplied to the MA board through CN2000 connector as long as the power cord is connected to the projector, even if the [Power] switch is turned off.

EMP-S3 2.6 RC Board Assembly The Remote Control (RC) board is equipped with sensors that detect (receive) infrared signals transmitted from the remote control. The two RC IR sensors are mounted on the front and rear of the projector. Rear IR Receiver Sensor Front IR Receiver Sensor RC Board Figure 2-15. RC Receiver Sensor The output signals (serial data) received by the sensors are sent to IC501 (PISCES2) on the MA board.
EMP-S3 2.7 Speaker The projector has a single 1 W built-in speaker that is at the rear of the projector. It can be used for monaural output of the sound that is input to the projector from a host computer or video source. The signal from the computer or video source is amplified by the audio control circuits on the AV board and then output to the built-in speaker through connector CN1701. Speaker Figure 2-17. Speaker The following diagram illustrates the circuits that control the speaker.
EMP-S3 2.8 Temperature Control 2.8.1 Sensors and Switches This projector is equipped with the devices shown in the table below in order to protect the safety of the operator and maintain general safety with regard to the projector itself by preventing abnormalities in operation. Table 2-3.
EMP-S3 TH Board The TH Board is attached to the Inner Exhaust Duct to detect the temperature of the lamp section. To prevent damage to the surrounding components from overheating, the power save controller on the MA board first provides a warning indication through the temperature indicator LED, and stops the output of the ballast when the temperature rises above a given level. TH Board Figure 2-20.
EMP-S3 Thermistor and Temperature Sensor Operation Analog/Digital converters in IC702 and IC703 (V850) on the MA board detect the temperatures of the Optical Engine and Power Supply sections by means of the two Lamp Thermistors at intervals of 1 second. Based on the measurement results, the CPU controls fan operations and power supply shutdown operations as necessary. Table 2-4.

EMP-S3 Operation Control The MA board is connected to the Lamp Thermistor. The driver CPU controls the operation of the four fans, Intake fan 1, Intake fan 2, Exhaust fan and Power Supply fan, based on the temperatures detected by the thermistor. The signals output by IC1100, the driver CPU on the MA board, are used to change the output from the fan drive regulator circuit on the MA board in order to control Intake and Exhaust fans.
EMP-S3 2.9 LED Indicators The MA board has three LEDs that indicate the operating status of the projector. The status indicators are located on the upper case unit. Temp indicator Lamp indicator Power indicator Figure 2-24. Status Indicator LEDs Location The following tables show what the indicators mean and how to remedy any problem indicated.
EMP-S3 Indicator Status Power Red Red Projector Status Problem and Remedy Take out the lamp and check if it is broken. If the lamp is not broken, put it back in and then turn the power on. If the lamp still does not turn on, replace it with a new lamp. If this does not solve the problem, stop using the projector and disconnect the power cable from the electrical outlet.
