Make	Model	Symptom	Problem	Solution	By
SAMSUNG	UN40H6400AG	TV turns on but the backlight flashes or then goes out, the backlight does not remain on even if disconnected from the main PCI, in this model the normal thing is for the backlight to turn on as soon as the power supply is disconnected from the main	After excluding the possibility of a defect in the LED bus, check the voltage at the point in common between the components d9802, d9801 and q9802, a voltage well below 1.6 causes the backlight to trip, in the tests sound q9802 was removed from the circuit with this, the voltage returned to around 3v at this common point of the 3 components, this with the PCI disconnected from the main	Left without the q9802	Direto no defeito
SAMSUNG	UN39EH5003	Doesn't work	Defective +5v integrated circuit	Measuring the voltage at the remote control sensor socket it was 2.8v. Following the trail of this voltage I reached the defective IC202 integrated.	ELETROFEPAR
SAMSUNG	LN40C530F1M	Backlight keeps blinking like shaking	Replace dp 804	Leaky diode	DANGRA ELETRÔNICA SÃO PAULO
SAMSUNG	PL43F4000	Sometimes it turns on, sometimes the LED doesn't even light up	Moisture in the series resistors at the ac input	Resolve	Carlos Eletronica JL
SAMSUNG	PL43F4000	Flashed standby, remained lit and did not obey remote control	Sem 15v ,vs e va ,5v normal	Photocoupler connected to qs807 at power supply	Hndrsn
SAMSUNG	43NU/RU7100	Power supply has blown fuse	Fet ey18 (you can use 13nm60) cp801 and cp805 swap the two, measure between drain and power supply if it gives 500Ω on both sides the pwm ci is also burned (fa1a60)		HP eletrônica
SAMSUNG	UN50MU6100	Blinks stby, and LEDs blink but do not turn on, tsound is no sound or image, measuring at the main 12v power connector they oscillate	Fuse f233, which goes to the output of ci q211 near the connector, open and shorted smd capacitor on the right side of the v-com, position c20, I replaced it and it was perfect		Eletrônica Portugal
SAMSUNG	PL51F4000AG BN44-00599A P51HF	Normal power on does not generate video, slight blinking	Defect on the power supply board, mosfet transistor qx854 partially shorted	Test before ysus plate, plate	Eletrônica Sorriso Maike
SAMSUNG	LN40B530P2M	Does not turn on (normal power supply)	C207 short (it is next to the ic8005 memory)	Capacitor elimination	duc40rj
SAMSUNG	UN65HU8500GXZD	Doesn't start. Defective standby power supply. defect caused by the plastic underneath the PCI which rots and releases conductive oil and which also corrodes the board	Replacement of the IC pwm of the standby power supply s3330 position ics801 and the 1Ω resistor position rs801. Clean the board thoroughly and check for possible corrosion spots that could cause other defects on the board.		rafaelmoraes99
SAMSUNG	PL43F4900	Sometimes it doesn't turn on, it doesn't even light up on stand by, sometimes it turns on	Do a test with a thermal blower or a head heater on the main board, if it gets hot and turns off, replace the capacitors c1024 and c1025 with 10uf/25volt electrolytic capacitors, note: observe the polarity, just find the negative side with a multimeter on the device's chassis		reginaldo moronte,eletronica junior caldas novas
SAMSUNG	DA-E750	The sound comes out very bassy and even with the volume at maximum, it is low.	Replace ic701 - ic7002 (s4560 amplifiers) and check/replace all capacitors in the amp circuit.		Neu
SAMSUNG	LN32C450E1M	Does not turn on, the standby LED lights up (time on, time off)	Check cold solder on the rm811 smd resistor located at the power supply, just resolder it and run for hug.		Eletronica Oliveira
SAMSUNG	LC46C530F1M	Doesn't start	TV does not come out of standby, replace the ic203 in the main one, aoz1031. aoz1035 is compatible. good luck		AXCELL ASSIST TEC
SAMSUNG	LT27A550	Does not turn on LED turns on and off, no manual control is left, accepts command via control but nothing happens.	Ic 204	Input voltage ok, no output voltage just replace ic204 z1033a easy to find in scrap.	Assistec lg
SAMSUNG	UN65NU7100	TV heats up and only the sound disappears	Speaker with the coil scraping and activates the sound amplifier protection. defect caused by using sound at maximum volume.	Replace speakers	SANTOMEL
SAMSUNG	UN32EH5000G	Stand by LED flashes 5 times but does not turn on	Cold solder on the processor	2 minutes with station 850 did the trick. lol... _good luck!	Jhone eletronica
SAMSUNG	UN32EH4000G	Power supplys ok but not on standby led off	Ci 202 shorted or leaking	Replaced sleep.... good luck!	Jhone eletronica
SAMSUNG	UN50TU8000G	LED bus does not light	LED control sector photocoupler, change without testing		HAHNRAHN
SAMSUNG	T27A550	Turning on and off alone, changing channels and other functions alone, intermittent defect	Touch keyboard replacement (control sensor plate)		reginaldo moronte,eletronica junior caldas novas
