SECTION 3 CIRCUIT DESCRIPTIONS CIRCUIT DESCRIPTIONS POWER ON AND OFF The power supply runs all the time when AC is applied. The use of the power supply creating Stand-By Voltage supplies eliminates the need for a Stand-By transformer. The following explanation will describe the Turning ON and OFF of the projection television. The Microprocessor I001 generates the ON-OFF control signal from pin (53). The logic states of this pin are High = On and Low = Off.
CIRCUIT DESCRIPTIONS · Shorted SW +5V (IC02) on Signal PWB through PROTECT 1 to (D940) on Sub Power Supply PWB ohm, however it could be any low ohm value. When the current demand increases, the voltage drop across the resistor increases. If the voltage drop is sufficient to reduce the voltage on the base of the transistor, the transistor will conduct, producing a Shutdown signal that is directed to the appropriate circuit. NOTE: PROTECT 1 will not go below 2.2V even if the 5V or the 3.3V lines are open.
CIRCUIT DESCRIPTIONS HOT GROUND SIDE SHUT DOWN SENSING CIRCUITS (INTERNAL TO IP01) LATCHED SHUT DOWN MONITORS (AC must be removed to recover) 1. Pin 4 is monitored for Over Voltage internal to IP01. 2. IP01 itself is monitored for Excessive Heat. This block is labeled T.P.O. (Thermal Protection Overload). RECOVERING SHUT DOWN INPUT (Driver IC will recover on it’s own when trouble is removed) 3.
CIRCUIT DESCRIPTIONS sistor turns Off, generating a High on its collector. This output High is routed through D705 to pin (1) of Connector PQD2 called PROTECT and Shut Down occurs as described above. called PROTECT and Shut Down occurs as described above. 9. Side Pincushion failure generating a High. (D702, and D703). The Side Pin Cushion op-amp circuit is comprised of I701. If a problem occurs in this circuit it creates a High from pin 7 of I701.
CIRCUIT DESCRIPTIONS NOTE: If the 5.5V or the 3.3V regulators OPEN, the set will not go into shut down, they must have a short to produce a shut down input on PROTECT 1. The set will shut down after the Screen go excessively bright, but this is from the 115V over current sensor, not PROTECT 1. When the power supply is in Stand By, the Short Detection circuit could activate. By turning off Q919, no accidental shut down operation can occur.
CIRCUIT DESCRIPTIONS LED USAGE The Visual LEDs are useful in Trouble Shooting. Without removing the back cover, some diagnostics can be made. By observing the operation of the Red and Green LEDs, the technician can determine if the Deflection Power Supply is running. By monitoring these LEDs at turn on, one can determine if a line is loaded. If an LED tries to light then goes off, or only lights dimly, a loaded condition should be considered.
CIRCUIT DESCRIPTIONS V BLK The Vertical Blanking pulse is generated from the Vertical output IC, I601 pin (11). This pulse normally operates at 21V P/P. IR The Infrared Pulses coming from the remote control are routed through the Deflection PWB to the Digital Convergence Unit. During DCAM (Digital Convergence Adjustment Mode), the Remote Control provides manipulation pulses for the DCU. DIG RGB/ BUSY This indicates Digital RGB and BUSY.
CIRCUIT DESCRIPTIONS 30Kv HV 30,000 volts DC supplied to the CRTs anodes. TO DEFLECTION YOKES Horizontal and Vertical deflection wave forms driving the deflection yokes. MAGIC SWITCH Output from the DAC1 (I006 pin 7) when the customer selects HD FOCUS from the customer’s menu. This energizes HD FOCUS, (Magic Focus). SERVICE ONLY SWITCH Enters the Digital Convergence Adjustment Mode, (DCAM). · H.
CIRCUIT DESCRIPTIONS A sample of the High Voltage is output from the Flyback transformer TH01 pin (12). This voltage is sent to pin (9) of the High Voltage Driver IC IH01. This voltage is compared to the reference voltage available at pin (12). If there is a difference between the two voltages, an error voltage is generated and output from pin (10) and input again at pin (11) where it manipulates the PWM (Pulse Width Modulation) signal producing the Horizontal Drive signal output from pin (1).
CIRCUIT DESCRIPTIONS • HD FOCUS SENSORS AND INTERFACE • MICROPROCESSOR • RAINFOREST IC (Video Processor). • SERVICE ONLY SWITCH • MAGIC FOCUS (HD Focus) activation control. THE DIGITAL CONVERGENCE UNIT (DCU) The DCU is the heart of the Digital convergence circuit. Held within are all the necessary components for generating the necessary waveforms for correction, and associated memories for the adjustment data and Magic Focus Data. The Block above shows the relationship of the DCU to the rest of the set.
CIRCUIT DESCRIPTIONS the BUSY line. As long as the BUSY line is active, the Main Microprocessor ignores the IR signal. ON SCREEN DISPLAY PATH: MICROPROCESSOR SOURCE FOR OSD: The On Screen Display signal path is shown with the normal OSD information such as Channel Numbers, Volume Graphic Bar, Main Menu, sent from the Main Microprocessor to the Rainforest IC IC01 pins 37, 38 and 39. These are positive pulses, about 5 V p/p and about 3uS in length dependant upon their actual horizontal time for display.
CIRCUIT DESCRIPTIONS The Microprocessor communicates with the following ICs: The ABL voltage is determined by the current draw through the Flyback transformer. As the picture brightness becomes brighter or increases, the demand for replacement of the High Voltage being consumed is greater. In this case, the flyback will work harder and the current through the Flyback increases. This in turn will decrease the ABL voltage. The ABL voltage is inversely proportionate to screen brightness.
CIRCUIT DESCRIPTIONS in the EEPROM, such as the window for Closed Caption detection. Data and Clock lines are SDA1 from pin (2) of the Microprocessor to pin (5) of the EEPROM and SCL2 from pin (3) of the Microprocessor to pin (6) of the EEPROM. Data travels in both directions on the Data line. FLEX CONVERTER UC01 The projection television is capable of displaying NTSC as well as ATSC (DTV) including HD (High Definition).
CIRCUIT DESCRIPTIONS Communication from the Microprocessor via pins (59) SDA2 and (60) SCL2 to the Rainforest IC pins (31 and 30) respectively. ON THE TERMINAL PWB and a little more dark just before it arrives. This gives the impression that the signal pops out of the screen or a 3D effect. The Microprocessor communicates with the 3D Y/C IC via I2C bus data and clock. The communications ports from the Microprocessor are pins 59 (SDA2) and 60 (SCL2) to the 3D Y/C I301 pins (59 and 60) respectively.
CIRCUIT DESCRIPTIONS The Microprocessor uses a combination of I2C Bus communication and the Serial Data, Clock and Load lines for control. The I2C communication scheme only requires 2 lines for control. These lines are called SDA and SCL. Serial Data and Serial Clock respectively. SRS AUDIO +29V REGULATOR INDICATED BY D912. The SRS Audio +29V supply is generated from pin (8) of T901. This output is rectified by D910 and filtered by C915.
