§ SAFETY INSTRUCTIONS
§ SAFETY PRECAUTION
WARNING: Service should not be attempted by anyone unfamiliar with the necessary precaution on this receiver. The following are the necessary precaution to be observed before servicing. 1.Always discharge the picture tube anode to the CRT conductive coating the picture tube. the picture tube is hightly evacuated and if broken, glass fragments will be violently expelled. Use shatterproofgoggles and keep picture tube away from the body while handling. 2.When replacing chassis in the cabinet,always be certain that all the protective devices are put back in place, such as; nonmetallic control knobs, insulating covers, shields, isolation resistor-capacitor network, etc 3.Before retuning the set to the customer, always perform an AC leakage current check on the exposed metallic parts of the cabinet, such as antennas, terminals, screwheads, metal overlays, control shafts etc, to be sure the set is safe to operate without danger of electrical shock. Plug the AC line cord directly into a AC outlet. Use an AC voltmeter having 500 ohms per volt or more sensitivily in the following manner. Connect a 1500 ohm 10 watt resistor, paralleled by a 0.15 mfd, AC type capacitor, between a known good earth ground( water pipe, conduit etc) and the exposed metallic parts, one at a time. Measure the AC voltage across the combination of 1500 ohm resistor and 0.15 mfd capacitor. Reverse the ac plug at the ac outlet and repeat AC voltage measurements for each exposed metallic part. Voltage measured must not exceed 0.3 volts RMS. This corresponds to 0.2 milliamp, AC. Any value exceeding this limit constitutes a potential shock hazard and must be corrected immediately.

§ PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in this chassis have special safety-related characteristics. These characterictics are often passed unnoticed by a visual inspection and the protection afforded by them cannot necessarily be obtained by using replacement components rated for higher volage, wattage, etc.Replacement parts which have these special safety characteristics are identified in this manual and its supplements;electrical components having such features are identified by shading on the schematic diagram and the parts list. Before replacing any of these components, read the parts list in this manual carefully. The use of substitute replacement parts which do not have the same safety characteristics as specified in the parts list may create shock, fire or other hazards.
§ SERVICE NOTES
1.When replacing parts or circuit boards, clamp the lead wires to terminal before soldering. 2.When replacing a high wattage resistor(metal oxide film resistor)in the circuit board keep the resistor min 1/2 inch away from the circuit board. 3.Keep wires away form high voltage or high temperature components.

4. EXPLAINATION OF CIRCUIT OPERATION 1) VIN terminal, start-up circuit A start-up circuit is to start and stop a operation of a control IC by detecting a voltage appearing at a VIN terminal (pin-9). At start up of a power supply, when a voltage at the VIN terminal reaches to 8V by charging up C806 by the function of a start-up resistor, Rs, a control circuit starts operating by the function of the start-up circuit. As shown in Fig. 2, since a circuit current is suppressed 200§¸ maximum ( at VIN = 7.5V ) until the control circuit starts its operation. After the control circuit starts its operation, power source is obtained by smoothing voltage appearing at L1 winding. Once the control circuit starts operating, as its voltage doesn't reach the fixed voltage at once, VIN terminal voltage starts dropping. However, as a shut-down voltage is set low (at 4.9V), while VIN terminal voltage reaches a shutdown voltage, L1 winding voltage reaches the fixed voltage earlier so that the control circuit can continue on operating.

2) Osciliator, F/B terminal voltage (Pin #7) A oscillator generates pulse signals which turns a power transistor on and off by making use of charge and discharge of CI and C2 incorporated in the Hybrid IC. Constant voltage control of a switch-mode power supply is performed by changing both ON- time and OFFtime except when the load is light (ex. remote control stand-by mode of TVs). Fig. 4 shows how the oscillator works when the Hybrid IC independently operates (with no F/B nor INH signals). When the power thransistor is on, C2 Is charged to the set voltage (approx 2.3V at Ta =25°C). On the other hand, C1 starts charging up through R1 from almost 0V and the voltage across C1 increases in accordance with the inclination determined by the product of C1 and R1. When the voltage across C1 reaches approx. 0.75V (Tc=25°C). the output from the oscillator is reversed and the power transistor turns off. At the same time C1 is quickly discharged by the function of a internal circuit of the oscillator and the voltage across it decreases to almost 0V. When the power transistor turns off, C2 starts discharging through R2 and the voltage across C2 decreases in accordance with the inclination derermined by the product of C2 decreases to about 1V. the output from the oscillator is reversed again and the transistor consequently turns on. The power transistor continues turning on and off by repeating the above-mentioned operations.

As the circuit in Fig. 3 shows, the ON-time is controlled by changing a current charged by C1, which is as the result of that the detection winding (L1),which detects a change of voltage in a secondary side, connected to the sensing terminal (Pin No. 7) has the current in accordance with an output signal from an output voltage detection circuit (an error amplifier) built in. As an AC input voltage to the power supply gets the higher and a load current the smaller, the current flowing to the SENS terminal gets the larger, and the ON-time gets the shorter.
3) Function of INH terminal (Pin #6), control of OFF-time Signal to the INH terminal is used as inputs to COMP.1 and COMP.2 inside of the control IC. A threshold voltage of COMP.1 VTH1 is set at 0.75V (Ta=25°C) and an input signal to a drive circuit becomes almost 0V (the power transistor is in OFF mode) when a voltage at the INH terminal reaches the VTH1. As long as the INH terminal voltage does not get lower than VTH1. the power transistor sustains OFF mode. On the other hand, a threshold voltage of COMP.2 VTH2, is set at 1.5V (Ta=25°C).When the INH terminnal voltage reaches VTH2, an output from COMP.2 reverses and, as a result, C2 starts firing and a voltage across C2 drops to almost 0V in a moment. As the result of this immediate discharge of C2, the OFF-time of the oscillator which has been determined by the product of C2 and R2 (/ 55 ¥ sec) can be quicker up to approx. 2¥sec. As long as the INH terminal voltage does not get lower than VTH2, AVoltage across C2 stays at almost 0V and a output from the oscillator keeps the power transistor being on. The relation between the INH terminal voltage and the function of the oscillator described above is shown in Fig. 6 and Fig. 7

4) Quasi-resonant operation By inputting a voltage signal which is synchronized with the energy discharge time of a secondary winding of a transformer to the. INH terminal, quasi-resonant operation can be achieved. As shown in Fig. 8 , the voltage of L1 winding which is synchronized. with the energy discharge time of a secondary winding. S1. shall be input to the INH terminal through D805 and R807. Since VTH2 is set at 1.5V typical, a voltage at the INH terminal. VINH, shall be set at 2V.

when the power transistor turns off and a voltage higher than VTH2 is applied to the INH terminal, C808 immediately discharges and then starts charging again. Even after the discharge of energy of a secendary winding is completed, VINH does not immediately increases. When it gets lower than VTH2 after the time,tr, which is determined by the production of internal impedance of the IC and CINH, has past, the transistor turns on.

5) Drive circuit The STR-S5707 applies the proportional drive system in order to minimize turn-on and satruration loss, and storage time. In the conventional RCC system, turn-on loss and switching noise due to the surge current appearing when the power transistor turns on are high as because the transistor is driven by the drive current shown in Fig. 10-1. In addition, since is decreases linearly when the transistor turn off and a peak value of IB2 is not large, the storage time is long and the VCE(sat) voltage is high, which results in large turn-off loss. The circuit and the waveforms of the proportional drive system which is applied to the STR-S5707 in order to reduce these switching loss and shorten the storage time are shown in Fig . 10 and Fig. 10-2 respectively.

6) OCP (overcurrent protection) function Overcurrent protection is performed pulse by pulse by directly detecting collector current of the power transistor. Configuration of the OCP circuit is shown in . Detecting voltage is set to -1V below a reference point of GND (ground). In additlon, since the detecting voltage is set by a comparator, very stable characteristics against temperature is achieved and drift of the detecting voltage against temperature change is almost 0V.

7) Latch circuit It is a circuit which sustains an output from the oscillator low and stops operation of the power supply when overvoltage protection (OVP) circuit and thermal shutdown (TSD) circuit are in operation. As the sustaining current of the latch circult is 500¥A maximum when VIN terminal voltage is 4V. the power supply circuit sustains the off state as long as current of 500¥A minimum flows to VIN terminal from a start-up resistor. In order to prevent a malfunction to be caused by a noise and so on, delay time is provided by C1 incorporated in the IC and, therefore, the latch circuit operates when the OVP of TSD circuit is in operation, of an external signal input is provided. for about 10¥sec or longer.In addition, even after the latch circuit start operating, the constant voltage regulator (Reg) circuit is in operation and the circuit current is at high level. As a result. VIN terminal voltage rapidly decreases. When VIN terminal voltage becomes lower than the shutdown voltage, VIN(OFF), (4.9V typical), it starts in -creasing as the circuit current is below 500¥A. When it reaches the ON-state voltage. VIN(ON), (8V typical), VIN terminal voltage starts decreasing because the circult current increases again.
23
when the latch cirguit is on. VIN terminal voltage increases and decreases with- in the range from 4.9V typical to 8V typical and is prevented from abnormally rising. Fig. 12 shows an example of V IN terminal voltage waveform.Cancellation of the latch-is done by decreasing VIN terminal voltage below 3.3V. The power supply can be restarted after disconnecting an AC input to the power supply once.

8) Thermal shutdown, circuit It is a circuit to trigger the latch circuit when the frame temperature of the IC exceeds 150°C (typical). Although the temperature is actually sensed at the control chip. It works against overheating of the power transistor as the power transistor and the control IC are mounted on the same lead frame. 9) Overvoltage protection circuit It is a circuit to trigger the latch circuit when VIN terminal voltage exceeds 11V (typical). Although it basically functions as protection of VIN terminal against overvoltage, since VIN terminal is usually supplied from the drive winding of the transformer and the voltage is proportional to the output voltage, it also functions against the overvoltage of secondary output which causes when the control circuit opens or in some other events.

2) EXPLANATION OF THE OPERATION ¤ There is very little voltage drop at £ R821(1W 0.68) of 123 [V] line. ¤LIn case that the overload occurs at the rear of 123[V] line, the increase of the voltage drop at R821 bring down the base voltage of the Q806 so as to drive the Q806 ¤ØBecause of the overload at the rear of the R821, the voltage of the £ point decreases. And this makes Q806 turn on so that a voltage is applied to the #29 of I701. ¤OEIn case that OCP operates by the #29 of the I701, the set is protected by power off (#32 of I701¡ LOW).
