Section 3 Circuit Description
The main functions of each board in this unit are as described below. . A board This board mounts an HD15 connector and two HDMI connector interfaces. It processes a video signal together with the signal from an option board using a scaler and outputs data to the display panel. This board also outputs the selected audio signal to the SP board. . JT board This is a relay board used for connecting the option board and A board of slot 2. . H1 board This is a user interface board. This board mounts [POWER], [INPUT]/[ENTER], [MENU], [UP], [DOWN], [RIGHT], and [LEFT] buttons. . H2 board This board mounts two-color LED, which displays the status of this unit, and a remote control photosensing block. . LOGO board This is an LED board used for shining a SONY logo. . SP board This board mounts a speaker output terminal for audio output. . G6 board This is a power board that has output voltages of STBY5 V, 5 V, 12 V, and 13 V.
3-1. A Board
The A board mounts HD15 (CN1), HDMI1 (CN12), and HDMI2 (CN11) as a video input terminal. The signal from option slot 1 is input from CN14, and the signal from option slot 2 is input from CN13 through the JT board. The RGB/YPbPr signals from HD15, and slots 1 and 2 are directly input to a scaler circuit (U5). HDMI1 and HDMI2 signals are switched using an equalizer (U20), and the selected TMDS signal is input to the scaler circuit. An equalizer switches signals and controls the signal output, by the port control (SEL_H and CE_H) from a scaler circuit. The CVBS and Y/C signals from an option slot are input through a p-type filter circuit to a scaler circuit. The video signal from which an HDMI signal was eliminated is input to a scaler circuit without passing through a switch circuit. However, the RGB sync signals from slots 1 and 2, and HD15 are selected using a switching circuit (U3) by HV_SA and HV_SB signals and input to a scaler circuit. The input signal from HD15 is used for a video sync signal. It is switched using a switching circuit (U4) by a SYNC_MO signal and input to the port of a scaler circuit that differs from the case of an H sync signal. In a scaler circuit, resolution is converted according to the display panel, and various picture qualities as well as wideangle setting or zoom setting are set and LVDS-transferred to the panel through CN2. There are the analog input from a mini-jack (CN3), slot 1, or slot 2 and the digital input from HDMI in an audio input. An analog audio signal is input to an audio processor circuit (U14). The audio signal from HDMI is output from a scaler circuit as an I2S signal and input to U14. The audio processor circuit is controlled by I2C to switch the input and set the sound quality and volume. The selected audio signal is passed through an amplifier circuit (U17) and output to the SP board through CN10. The mini-jack input cannot be only selected as the function of the main unit only during HD15 input, but also it can be selected as an audio input during conversion of DVI into HDMI. An audio signal is muted by the software control of an audio processor and the hardware control of an amplifier.

This unit is used for BKM-FW20 that has RS-232C and Control-S as an option board. The RS-232C (UART) signal from an option slot is selected using a switching circuit (U41). The signals from option slots 1 and 2 are selected when OP1_RS_EN or OP2_RS_EN is set low on the option side. OP1_RS_EN or OP2_RS_EN is low during initial setting of BKM-FW20. Slot 2 has priority when both OP1_RS_EN and OP2_RS_EN are low. The selected RS-232C signal is connected to the control port or firmware write port of a scaler circuit using a switching circuit (U31). It is switched to the firmware write port position when an FWE signal is set low on the option side as the control of U31. The FWE signal is high during initial setting of BKM-FW20. The signal (IR) from a remote control photosensing block is shifted in level to a signal (IRO) of 5 V to 3.3 V using U27, branching to each option slot connector. The Control-S signals (OP1_IRI and OP2_IRI) from the IRO signal and each option slot are input to a switching circuit (U29), selected, and input to the IR port of a scaler circuit. Which signal to select is determined by controlling the OP1_S_EN and OP2_S_EN signals from each option. When BKM-FW20 is not connected, each signal is set high and an IRO signal is selected. The IRI signal from each slot is selected when OP1_S_EN and OP2_S_EN signals are set low. Slot 2 has priority when both OP1_S_EN and OP2_S_EN signals are low. The OP1_S_EN and OP2_S_EN signals are low during initial setting of BKM-FW20. The A board mounts a real time clock circuit (U11). The real time clock circuit is controlled by I2C. A timer function is controlled based on the time read operation by polling from a scaler. During timer correction, a timer is adjusted to an error of 3 ppm by outputting a pulse of 1 Hz to CN8 and putting a correction value in the register of IC according to the obtained measurement value. The corrected value is obtained in the adjustment stage of a single board at a factory and stored in memory. It is not lost even in the state in which the power is not connected. A button battery is connected to RTC. Even with the AC power not connected, power is supplied to IC so that U11 operates continuously. The backlight of LCD is controlled by the PWM signal (BL_CONT) from a scaler circuit. The PWM signal is inverted using Q20, integrated using R373 and C356, and output to CN19 as a DC signal (INV_ADJ). The On/Off signal (PBIAS) of a panel inverter is output from the dedicated port of a scaler and then output from CN19 as an INV_ON signal. 3-2
A PWM signal (LOGO_PWM) is output from a scaler circuit to the LOGO board that shines a SONY logo. The output signal of an amplifier circuit (U28) is integrated to drive LED on the LOGO board as a DC signal. This LED is turned on and off using the LOGO_EN signal from a scaler circuit. An option board is discriminated by discriminating OP1_SENSE1, OP1_SENSE2, OP2_SENSE1, and OP2_SENSE2 signals at the ADC port of a scaler circuit using a voltage. These signals are passed through IC (U30) and switched using the control signals (Q_SEL1 and Q_SEL2) from the scaler circuit. Only when the power is turned on, these signals are switched and the option board is discriminated. After that, the output signal U30 is switched to power temperature (PS_TEMP) and polled as a self-diagnosis function.
3-2. H1 Board
A button input signal is sent to the A board as a DC voltage signal. 1 V, 1.5 V, and 2.2 V are sent to an ADC_IN2 signal when you press the [MENU], [INPUT], and [LEFT] buttons. 1 V, 1.5 V, and 2.2 V are sent to an ADC_IN1 signal when you press the [RIGHT], [DOWN], and [UP] buttons. 0 V is sent when you press only the [POWER] button as a PWR_KEY signal. Each signal is set to 3.3 V when you press no button.
3-3. H2 Board
The H2 board mounts an infrared remote control photosensor (IU1) and sends data to the A board as an IR signal. This board also mounts two-color LED (ID5) that displays the status of this unit. The LED controls light emission by controlling the cathode.
FWD-40LX2F FWD-40LX2X
3-4. G6 Board
AC input/rectification block CN901 on the G6 board is connected to an AC inlet and AC power is input from the AC inlet. The input AC power is passed through an AC noise filter consisting of C910, C901, C904, L901, L903, and L904 and bridge-rectified using BD901. PFC converter AC power is rectified using BD901 and the power factor is improved using a PFC converter consisting of Q911, IC911, T911, D912, C920, and C921. Moreover, an output voltage is increased and stabilized to 390 VDC. The smoothed output voltage is supplied to a standby converter and main converter. Standby converter 5 V (5 VD and 5 VS) and 12 V are output from a switching converter consisting of IC931 and T931. 5 VD is output from CN931 (pins 2 to 4), and 5 VS is output from CN931 (pin 8). 12 V is output from CN950 (pins 6 and 7). During standby, however, the output voltage that is not increased, but smoothed is supplied from a PFC converter. Main converter 17 V and 13 V are output from a switching converter consisting of IC950, IC951, Q950, Q951, T950, and T913. 17 V is output from CN951 (pins 1 to 5), and 13 V is output from CN950 (pins 2 and 3). Main ON/OFF control A PFC converter and main converter are turned on and off by CN931 (pin 1) when a PS signal is set high and low using a microcomputer. Q934 is turned on when a PS signal is high. A PFC converter is turned on when Q931 is turned on. A main converter is started when IC913 is started after Q931 is turned on. Q934 is turned off when a PS signal is low. A PFC converter and main converter stop operation when Q931 is turned off and when IC913 is stopped.

SAFETY CHECK-OUT
After correcting the original service problem, perform the following safety checks before releasing the set to the customer : Check the metal trim, "metallized" knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below. LEAKAGE TEST The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 3.5 mA. Leakage current can be measured by any one of three methods. 1. A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers' instructions to use these instruments. 2. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job. 3. Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The "limit" indication is 5.25 V, so analog meters must have an accurate lowvoltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 20 V AC range are suitable. (See Fig. A)
