Make	Model	Symptom	Problem	Solution	By
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
SAMSUNG	UN48H4203AG	The TV turns on normally with the image, then it takes effect as if the defect were the display, the image fades and freezes as if it were actually the screen.	Defect was the driver of the vcon ci ck1 board (bm81224muv qfn) changed, defect resolved...		ALVES.TEC ELETRÔNICA.CAMARAGIBE/PE

SAMSUNG	UN65F8000AGXZD	TV doesn't turn on, just the backlight keeps flashing with the relay beating.	Check two cis responsible for the backlight on the power supply PCI. see slc1013m and slc2013m. If the backlight flashes at the top and bottom, it means that the center LEDs are not lighting up and the possible defect is in the SLC1013m and if it only flashes in the center of the screen, and does not light up at the top and bottom, tsound is a possible defect in the SLC2013m.	Replace of cis slc1013m and/or slc2013m	rafaelmoraes99
SAMSUNG	LN32D400E1G	Doesn't start	Ci202 smd noneclstura 90108 booster from 5v to 3.3v	Changing the ci202 I removed it from another samsung board	Eulercell
SAMSUNG	UN43RU7100	Blowing fuse, rectifier bridge and MOSFET.	Ceramic capacitor next to the diode next to the qp801cs mosfet. Tsound is one on the diode and one on the MOSFET.	Changing ceramic capacitors. qp801cs rectifier bridge, and fuse.	Lucaseweb
SAMSUNG	UN32FH4205	Only the standby LED is on, all voltages are normal, you can press the power button and nothing happens.	Sem 3v3 no transistor q301	Replace ic301, it is close to the headphone connector.	Naldo Lima
SAMSUNG	PL43D490A1G RODRIGO COFFERI	It only turns on if the main board heats up	In addition to re-soldering everything on the other boards, check 1.2v at the output of ic204, on coil 202, if not, remove q206 next to the ic, aly	Rodrigo cofferi	Rodrigo cofferi
SAMSUNG	MAX G55	No cd/usb output	Opc capacitors 1, 3, 10, 13 - 10mf 16v from mpeg board
SAMSUNG	MX-C730	Doesn't start	Very oxidized power supply board, completely rusted jamp broken, cutting current.	Remove oxidized components and replace them.	JL-Eletronica (Jorge)
SAMSUNG	UN32J4000AG	Lower current from LED bars	Connect an 18k resistor from pin 35 vref of the bd9397 ci to ground. It also works for Sony TVs that use this ci		Sérgio
SAMSUNG	UN32J4290	The sound doesn't work	Burnt audio controller ic (ic301)	I checked the signals on the oscilloscope and tsound was no modulation on the 4 outputs, the input signals were ok, after the replacement it worked perfectly.	CDS_DIAS /LEDTECH
SAMSUNG	UN32F4200AG	Image with excessive brightness	V-con board damaged by cockroach piss near dc circuit	Tip given by Andre, thank you brother.	MILENIO ELETRONICA
SAMSUNG	UN40EH5000G	Standby LED blinks indicating that the TV has turned on, but the LEDs do not light up, all voltages are normal.	Metal connectors on the LED bars are loose, just tighten them and the LEDs will light up again.		DV Elêtronica
SAMSUNG	PL43F4000AG	Turning off after a while	Ts801cs and cs809s with cold soldering	Resoldering of ts801cs and cs809s	KAIO GARCIA
SAMSUNG	UN50RU7100	Does not turn on, LED is off.	Line 3.2 with zero volts. Cause: shorted smd capacitor c1409 below the processor heatsink.	It is used to shorting other capacitors on the same line.	ELETRONICA DANIEL
SAMSUNG	UN32J4000AG AG	No video	Absence of voff voltage, 7v9 zenner with leak	D14 diode replacement	diego boeira
