HC320SXN-VSFP3-21XX
EAJ62431801
CS 11002 LVDS INPUT SIGNAL
KLSTM111
AND IC 5562A
AND IN LG LED I FIND Q 1 IS SHORT WITHOUT BURN OUT
HIS NUMBER IS SMD CODE 123Z OR SMD CODE 132 N SMD 132Z IT IS THE SAME FET TRANSISTOR RESPONSIBLE TO VAA1 TO FEED THE GAMA IC AND ADD 1 VOLT CASCADE IN 2 STAGE TO INPUT *2
16*2 =32VOLT

IN SAMSUNG TECON USED THIS TRASISTOR
7N6
HOW THIS IS WORK
FIRST VOLT IS 3.3 PRODUCE ON THE SWITCH PIN 13 14 BUCK CIRCUIT
THIS 3.3 VOLT FEED TO PIN 9 TO ENABLE PIN TO MAKE OTHER BUCK WORK
THE SWITCH TAKE VOLT FROM 12 VOLT INPUT INTERNAL CHIP AND AFTER MONITOR THE VOLT INTERNAL THE FET VOLT SWITCH TO FLOW THE VOLT TO THE DRAIN OF MOSFET N CHANEL INSIDE THE CHIP INSIDE THE IC WILL MAKE THE VOLT ON SWITCH 12 11 AND INTERNAL PWM CIRCUIT WILL WORK WITH INTERNAL MOSFET AND WILL PRUDS 3.3 VDD VOLT
AND 3.3 WILL CONTROL IN OTHER CAUSE 3.3 IS DIGITAL ENABLE AND SMALL VOLT AND IF 3.3 VOLT FEED BACK OK VIA R4 THE AUTHOR PWM ON OTHER F MOSFET SWITCH WILL WORK DRAIN OF 25 -26 INTERNAL MOSFET
AND PRUDES VAA 1 AND MOSFET Q1 INTERNAL CONTROL IN AMP OF 16 VOLT TO FEED THE GAMA IC AND MAKE VGA IN CASCADE DIODE IN D5 TO A7 ADD VOLT WITH DRIVE B VOLT TO 2 STAGE 2*16 =32 VOLT + V DRIVE B
HOW IT WORK
AND WHEN NO VOLT ON PIN 36 DRIVE P
VOLT CHARGE C35 C32 C37 AND AND
AND THE PIN36 WILL CHARGED BY NEGATIVE VOLT
AND WHEN THE PIN 36 DRIVE IS POSITIVE VOLT IT WILL ADD TO THE VOLT POST IN C35 VIA A7 DIODE AND C27 VIA A72 DIODE
LIKE WHEN YOU ADD SERIAL BATTARE
AND VGL PRODUCE IN REVERSE WAY THE
SO THAT IS VGH INTER FEED BACK PIN 39 TO CONTROL ON PWM ON PIN 25-26
AND OUT THIS VOLT ON VGH M IS NOT USED IN THIS CIRCUIT AND CONTROL VGHM IS CONTROL IN WITH VGL IN THE VOLT APPLY ON MOSFET GATES OF LCD VERTICAL LINE AND (( CKV1 CJVB1 CKV2 CKVB2 AND STV VERTICAL FREQUNCY IS THE SEQUNCE CONTROL IN SEQUENCE OF OPEN CLOSE ODD EVEN VERTICAL LINE BY PULSE SCHEME SHAPE
AND CKV1 REVIRSE CKVB1
