SAFETY CHECKS

After the original service problem has been corrected, a check should be made of the following:

SUBJECT : FIRE & SHOCK HAZARD

1. Be sure that all components are positioned in such a

way as to avoid possibility of adjacent component shorts. This is especially important on those chassis which are transported to and from the repair shop.

2. Never release a repair unless all protective devices

such as insulators, barriers, covers, shields, strain reliefs, and other hardware have been reinstalled per original design.

3. Soldering must be inspected to discover possible cold

solder joints, frayed leads, damaged insulation (including A.C. cord), solder splashes or sharp solder points. Be certain to remove all loose foreign particals.

4. Check for physical evidence of damage or deterioration

to parts and components, and replace if necessary follow original layout, lead length and dress.

5. No leads or components should touch a receiving tube

or a resistor rated at 1 watt or more. Lead tension around protruding metal surfaces must be avoided.

6. All critical components such as fuses, flameproof

resistors, capacitors, etc. must be replaced with exact factory types. Do not use replacement components other than those specified or make unrecommended circuit modifications.

7. After re-assembly of the set always perform an A.C.

leakage test on all exposed metallic parts of the cabinet, (the channel selector knob, antenna terminals, handle and screws) to be sure the set is safe to operate without danger of electrical shock. Do not use a line isolation transformer during this test. Use an A.C. voltmeter, having 5000 ohms per volt or more sensitivity, in the following manner : connect a 1500 ohm 10 watt resistor, paralleled by a 15 mfd. 150V A.C. type capacitor between a known good earth ground (9water pipe, conduit, etc.) and the exposed metallic parts, one at a time. Measure the A.C. voltage across the combination of 1500 ohm resistor and 0.15 MFD capacitor. Reverse the A.C. plug and repeat A.C. voltage measurements for each exposed metallic part. Voltage measured must not exceed 0.75 volts R.M.S. This corresponds to 0.5 milliamp A.C. Any value exceeding this limit constitutes a potential shock hazard and must be corrected immediately.

SUBJECT : X-RADIATION

1. Be sure procedures and instructions to all service

personnel cover the subject of X-rays in current T.V. receivers is the picture tube. However, this tube does not emit X-rays when the high voltage is at the factory specified level. The proper value is given in the applicable schematic. Operation at higher voltages may cause a failure of the picture tube or high voltage supply and, under certain circumstances, may produce radiation in excess of desirable levels.

2. Only factory specified C.R.T. anode connectors must

be used. Degaussing shields also serve as X-ray shield in color sets. Always re-install them.

3. It is essential that the serviceman has available an

accurate and reliable high voltage meter. The calibration of the meter should be checked perio dically against a reference standard. Such as the one available at your distributor.

4. When the high voltage circuitry is operating properly

there is no possibility of an X-radiation problem. Every time a color chassis is serviced, the brightness should be run up and down while monitoring the high voltage

with a meter to be certain that the high voltage does not exceed the specified value and that it is regulating correctly. We suggest that you and your service organization review test procedures so that voltage regulation is always checked as a standard servicing procedure. And that the high voltage reading be recorded on each customer

5. When troubleshooting and making test measurements in a receiver with a problem of excessive high voltage, avoid being unnecessarily close to the picture tube and the high voltage compartment. Do not operate the chassis longer than is necessary to locate the cause of excessive voltage.

6. Refer to HV, B+and Shutdown adjustment procedures described in the appropriate schematic and diagrams(where used).

s invoice.

SUBJECT : IMPLOSION

1. All direct viewed picture tubes are equipped with an integral implosion protection system, but care should be taken to avoid damage during installation. Avoid scratching the tube. If scratched, replace it.

2. Use only recommended factory replacement tubes.

SUBJECT : TIPS ON PROPER

INSTALLATION

1. Never install any receiver in closed-in recess, cubbyhole or closely fitting shelf space over, or close to heat duct, or in the path of heated air flow.

2. Avoid conditions of high humidity such as : Outdoor patio installations where dew is a factor. Near steam radiators where steam leakage is a factor, etc.

3. Avoid placement where draperies may obstruct rear venting. The customer should also avoid the use of decorative scarves or other coverings which might obstruct ventilation.

4. Wall and shelf mounted installations using a commercial mounting kit, must follow the factory approved mounting instructions. A receiver mounted to a shelf or platform must retain its original feet(or the equivalent thickness in spacers) to provide adequate are flow across the bottom, bolts or screws used for fasteners must not touch and parts or wiring. Perform leakage test on customized installations.

5. Caution customers against the mounting of a receiver on sloping shelf or a tilted position, unless the receiver is properly secured.

6. A receiver on a roll-about cart should be stable on its mounting to the cart. Caution the customer on the hazards of trying to roll a cart with small casters across thresholds or deep pile carpets.

7. Caution customers against the use of a cart or stand which has not been listed by underwriters laboratories, inc. For use with their specific model of television receiver or generically approved for use with T.V. the same or larger screen size.

IMPORTANT SERVICE NOTES

1. X-RAY RADIATION PRECAUTION

1) Excessive high voltage can produce potentially hazardous X-RAY RADIATION. To avoid such hazards, the high voltage must not be above the specified limit. The nominal value of the high voltage of this receiver is

24.4kv at zero beam current (minimum brightness) under a 120V AC power source. The high voltage must not, under any circumstances, exceed 27kv (28.5kv). Each time a receiver requires servicing, the high voltage should be checked following the HIGH VOLTAGE CHECK procedure on page 6 of this manual. It is recommended as a parts of the service record. It is important to use an accurate and reliable high voltage meter.

2) This receiver is equipped with X-RADIATION PROTECTION circuit which prevents the receiver from producing an excessively high voltage even if the B+voltage increases abnormally. Each time the receiver is serviced, X-RADIATION PROTECTION circuit must be checked to determine that the circuit is properly functioning, following the X-RADIATION PROTECTION CIRCUIT CHECK procedure on page 6 of this manual.

3) The only source of X-RAY RADIATION in this TV receiver is the picture tube. For continued X-RAY RADIATION protection, the replacement tube must be exactly the same type tube as specified in the parts list.

4) Some parts in this receiver have special safety-related characteristics for X-RAY RADIATION protection. For continued safety, parts replacement should be undertaken only after referring to the PRODUCT SAFETY NOTICE below.

2. 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) Since the chassis of this receiver has hazardous

potential to ground whenever the receiver is plugged in (floating chassis), an isolation transformer must be used during servicing to avoid shock hazard.

2) Always discharge the picture tube anode to the CRT

conductive coating the picture tube. The picture tube is highly evacuated and if broken, glass fragments will be violently expelled. Use shatterproof goggles and keep picture tube away from the body while handling.

3) When placing 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.

4) Before returning the set to the customer, always

perform an AC leakage current check on the exposed metallic parts of the cabinet, such as antennas, terminals, screw-heads, 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 120V AC outlet (do not use a line isola-

tion transformer during this check). Use an AC voltmeter having 5000 ohms per volt or more sensitivity in the following manner.

Connect at 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. Voltage measured must not exceed 0.3 volts RMS. This corresponds to 0.2 millliamp. AC. Any value exceeding the limit constitutes a potential shock hazard and must be corrected immediately.

3. PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in this chassis have special safety-related characteristics. These characteristics 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 voltage, 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 Xray radiation or other hazards.

4. SERVICE NOTES

1) When replacing parts or circuit boards, clamp or bend the lead wires to terminals 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 form circuit board.

3) Keep wires away from high voltage or high temperature components.

GENERAL ADJUSTMENTS

1. GENERAL

In the majority of cases, all color televisions will need only slight touch-up adjustment upon installation. Check the basic characteristics such as height, focus and sub- basic characteristics such as height, focus and sub- bright.

4. EXPLANA TION OF CIRCUIT OPERATION

1) VINterminal, 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 VINterminal(pin-

9).At start up of a power supply, when a voltage at the VINterminal reaches to 8V by charging up C809 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, VINterminal voltage starts dropping. However, as a shut-down voltage is set low(at 4.9V), while VINterminal voltage reaches a shutdown voltage, L1 winding voltage reaches the fixed voltage earlier so that the control circuit can continue on operating.

2) Oscillator, 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 C1 and C2 incorporated in the Hybrid IC.

Constant voltage control of a switch-mode power supply is performed by changing both ON-time and OFF-time 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 ). On the other hand, C1 starts charging up through R1 from almost OV and the voltage across C1 reaches approx. 0.75V (Tc = 25 ). 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 OV. When the power transistor turns off, C2 starts discharging through R2 and the voltage across C2 decreases with the inclination determined 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 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 V

is in OFF mode) when a voltage at the INH terminal reaches the V lower than V set at 1.5V (Ta = 25 ). When the INH terminal voltage reaches V

is set at 0.75V (Ta = 25 ) and an input signal to a drive circuit becomes almost OV (the power transistor

result, C2, the OFF-tim 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 V

, A Voltage 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 D804 and R809. Since V

5) Drive circuit

The STR-S5707 applies the proportional drive system in order to minimize turn-on and saturation 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 l

long and the V

voltage is high, which results in large turn-off loss. The circuit and the waveforms of the proportional

)

is not large, the storage time is

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. 10-2 respectively.

6) OCP (overcurrent protection)function

Overcurrent protection is performed 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

addition, since the detecting voltage is set by a comparator, very stable characteristics against temperature is achieved and drift of the deteting voltage against temperature change is almost OV.

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 circuit is 500 maximum when VINterminal voltage is 4V. the power supply circuit sustains the off state as long as current of 500 maximum flows to VINterminal 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. VINterminal voltage rapidly decreases. When V than the shutdown voltage, V reaches the ON-state voltage. VIN(ON), (8V typical), V

(OFF), (4.9V typical), it starts in-creasing as the circuit current is below 500 . When it

increases again.

when the latch circuit is on. VINterminal 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 VINterminal voltage waveform. Cancellation of the latch-is done by decreasing VINterminal voltage below 3.3V. The power supply can be restarted 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 (typical). Although the temperature is actually sensed at the control chip. lt 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

lt 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.

5. OCP (OVER CURRENT PROTECTION) CIRCUIT

This circuit is designed to protect the circuit from over current due to overload occurred at the rear of 123[V] line

1) CONFIGURATION OF OCP CIRCUIT

2) EXPLANATION OF THE OPERATION

There is very little voltage drop at R423 of 123[V] line. In case that the overload occurs at the rear of 123[V] line, the increase of the voltage drop at R423 bring down the base voltage of the Q407 os as to drive the Q407 Because of the overload at the rear of the R423, the voltage of the point decreases. And this makes Q407 turn on so that a voltage is applied to the #31 of l701. In case that OCP operates by the #31 of the l1701, the set is protected by power off (#42 of l1701 LOW).
