PROTECTIVE FUNCTION OF STR-S6709
Digital Utopia - DAEWOO DIGITAL
OCP (Over Current Protection)
OCP IS OPERATED DIRECTLY BY DETECTION OF THE COLLECTOR CURRENT THROUGH Rocp (R808)
TSD (Thermal ShutDown)
TSD IS OPERATED IN THE CASE THAT FRAME TEMPERATURE OF THE IC IS OVER 150
OVP (Over Voltage Protection)
OVP IS OPERATED WHEN THE TERMINAL VOLTAGE OF #9 IS OVER 11V & BY FEED-BACK WHEN THE SECONDARY OUTPUT IS OVERVOLTAGE
LATCH FUNCTION
WHEN OVP/TSD IS OPERATED, LET THE OPERATION OF POWER CITCUIT SHUT DOWN BY MAKING THE OUTPUT OF OSCILLATOR TO LOW STATE

NO power
Troubleshooting
Stand-by LED doesn't light up no C806's VDC is approximately 280v
Digital Utopia - DAEWOO DIGITAL
Check F801 & D801
The following waveform is to drain of I801
320 Vp-p
no
Check the impedance value of between Source and Drain to I801 . If the value is near 0 ohm , I801 is dead
100KHz
Check if voltage to PW803 #7 is supplied to I701
Check the parts caused a shortcircuit to secondary circuit

NO power
Troubleshooting
no Relay (Y802) operation is OK yes
Digital Utopia - DAEWOO DIGITAL
If the base of Q803 is on 5V? yes Change Q803 or Y802 no Check stand-by power
no Check D802,R803 and D825
Is R803 is on 280Vdc ?
yes no
Check the I803 #1.
380 Vp-p
Check the primary circuits of SMPS IC , and replace defective parts
50~80KHz
yes Check the parts caused a shortcircuit to secondary circuit
