Make	Model	Symptom	Problem	Solution	By
SAMSUNG	UN49KU6400G	TV doesn't turn on, backlight keeps blinking halfway	LED bar shorted to the can	Cutting of the damaged track and jumper	ELETRONICA GARROM
SAMSUNG	UN32EH4000G	Flickering screen and duplicate image	Body	Replace the 0r resistor with a 510r resistor located on the v board - its number on the board is r48
SAMSUNG	UN40ES6100 Y3ER3XCC10718X	Flashing back light, only this power supply oscillating!	L9191 shorted	Replace the l9191 coil (lpd6d-dry ks-1220aak, swipe shape! You can replace it with another one from the same circuit with a different number and pinout!	BRAMBILA
SAMSUNG	PL51F4000	Restarting	3v3 processor power changed to 3v5.	Remove r817 and put a jumper in place, reducing the output voltage to 3.17v.	Valdecir Schena
SAMSUNG	LN37C530	Does not turn on, only in STB	Regulator h, cv	Equivalent, replacement, replacement of the aoz1031ai, I replaced it with the aoz1073pi and it worked well, all that replaces is the switching frequency, but nothing significant.	Davi.sls
SAMSUNG	UN40K6500AG	TV doesn't turn on only on ST BY.	Defective main board.	Shorted board swap, c382 and c383 10μF nano ceramic shorted, killing voltages on the board, located next to the ic206 8 pins.	RNSPTEC
SAMSUNG	UN40J5200	It turns on but is only on standby, when you press the power button, the standby LED turns off and comes back on and the LEDs do not light up.	Q206, ao4801(8-pin dual p-channel fet, soic 8) on the main board, close to the connector that comes from the power supply, with one of the fets changed.	Replace of q206 - ao4801.	Monitor Informática Campina Grande PB
SAMSUNG	UN32D5000PG ( VERSãO KS24) BN91-06362U/BN41-01747A	Turns on but does not activate the LED backlight and does not turn off via remote control	I found IC204(aoz1033ai) not generating the output voltage and I observed pin 6 of the IC which was at low level. It was Q200 with marking code 1e.	Replace q200	leitemarcellus
SAMSUNG	LN40C530	Doesn't start	Z1031a regulator, I replaced it with the z1021ha, used on another board, the only difference is the switching frequency, the 1031 is 600khz, the 1021 is 500khz.		Davi.sls
SAMSUNG	UN40H5103AG	Whitish image on the entire screen.	When I removed the flat that went to the plate on the right (looking from behind) the image remained normal on half of the screen. Defective capacitor CD07. I removed it and the problem went away.		Jamilton Jr.
SAMSUNG	UN32FH4205G UN32FH4205	Don't log in	No diode problem		Dede
SAMSUNG	UN32FH4003	Doesn't start	Oxidized and rusty jumper j812 without contact on the power supply board	Jumper redone the TV started working again, check the connection of all components or jumpers that are rusty and oxidized if you find the suspect replace or redo the contacts etc.. i.e. visual analysis	Shweize
SAMSUNG	PL50C450B1	Blurred image and whitish screen, with time it becomes normal	Oscilloscope signal with lack of set down ramp	Replaced the smk 1360 transistor on the ysus q6000.	DANGRA ELETRÔNICA SÃO PAULO
SAMSUNG	PL51F4500AG	Dead tv. totally inoperative	Open fuse regulator ic and adjacent components burned.	Replaced the stq7011k regulator IC with a strw6053s plus a disk capacitor and a 0.32Ω resistor, the power supply turned on, but with oscillating voltages and without turning on the TV. Found a shorted 18v zener on the photo coupler line plus an SMD resistor connecting the zener to the regulator IC. I replaced the resistor with a bridge and the TV worked normally.	Paulão Tchwrma
SAMSUNG	UN46F6100AG	Display freezing at the top on the right side of the screen, the display cof was found toasted	As I don't have a machine to change the CPF, it was resolved by removing it, it stopped paralyzing the image so it had the perfect color without details, remove the 3 side cofs on the right side of the display		Juliosantos
SAMSUNG	UN46D6900	Hits the relay and restarts and repeats over and over again	Altered led buses	Replace LED buses. resolved.
SAMSUNG	T22B300EW BN44-00505A	Doesn't start at all	Swap: ICM801(strw6052s), cm804(221pf,1kv), dm801(uf4007)/fp801s(4a), bd8015 (bridge rectifier to 6a).		WebLogs
SAMSUNG	T22B300 BN44-00505A	Touch panel lights up, no function, TV does not turn on	Power supply bn44-00505a, tracks near the chopper very thin, resistor rm801 burned, capacitor cm855 bloated	Replace rm855 for 2r5 1/2w under the board, replace cm855 for 1000µf 25v. thicken primary tracks with soldering / update software via usb or rewrite eepron	Jerolamo
SAMSUNG	UN32EH6030G	Duplicate image	In my case, I put some 3mm tape on the flat that goes on the display and it worked, it's a lot of work, I made several attempts		Marcelo
SAMSUNG	UN75AU7700G	They swim on canvas	LED bar and short to the chassis	The above components were replaced; device ok, remove the 4 2r7 resistors and insert a 4r7/2w one, reducing the voltage from 115v to 100v	Valdecir Schena
