Make	Model	Symptom	Problem	Solution	By
SAMSUNG	LN32D450	Does not work, stand by LED on activates power key, LED blinks but does not turn on.	Check voltage on ic205, 1.5v. absent. check possible short in c 1020, 1115, 1141	In my case, c1141 shorted. replace and go for the hug.	arock
SAMSUNG	632NW PLUS	Doesn't start. Sometimes the LED doesn't light up or it lights up dimly. if turned off for a few days, it works again for a while.	5.1v and 14v line with varying voltage	Replace the 5.1v (c109/c110 1000μF) and 14v (c113/301 820μF) line capacitors. all four were looking good and measuring ok. I just replaced it and it resolved it.	PIXEL ASSIST
SAMSUNG	UN48JU6020G	Power supply secondary completely dead/turning off after a while.	Cold solder on the main transformer of the power supply / if pin 1 of the icm801 has less than 170v, the polyester capacitor cm847 will be leaking.		Carlos Araújo 82 9 93677063
SAMSUNG	UN50TU8000G	Burning the LEDs	Backlight with voltage above normal.	Solution: remove r901 from 2.4Ω. and don't worry, it won't burn the LEDs again.	Eletrônica Evolução
SAMSUNG	LN32B350F1	Turns on without backlight, PFC 380v ok, after changing the caps. secondary did not turn on	Capacitor with bad insulation, ok capacitance 474nf, but faulty voltage (c1832) supply 1st transformer		Moraes
SAMSUNG	PL-50P5H	No image	Check 4 diodes na y-sus zd5016, zd5017, zd5023, zd5024		ibramo
SAMSUNG	SCM5550	No sound at output	Rd6 e rd1		Matias ERP
SAMSUNG	CL 29Z43 MQ	Does not turn on or st by lights up	Primary power supply zener diode dz 813 shorted.	Primary power supply zener diode dz 813 shorted	JR tec
SAMSUNG	UN40F5500AG	Does not accept functions/commands only from the remote control, the TV keyboard works normally	When taking voltage measurements on the control board, the IR pin had a voltage oscillating from 1.4v to 1.8v.	Defect in ic1201, after taking all measurements of IR line components. The only thing left was the ic1201 as a defect, after changing the ic, the IR voltage stabilized at 3v3 and started accepting commands via the remote control again.	EC
SAMSUNG	UN40F5500AG	Does not accept functions/commands only from the remote control, the TV keyboard works normally	When taking voltage measurements on the control board, the IR pin had a voltage oscillating from 1.4v to 1.8v.		EC
SAMSUNG	UN32J4000AG	Sem backlight, as normal	At first we thought it was a burnt out backlight, but in the end it was working 100%, the defect was caused by a smd 334 (330k) resistor that is positioned right next to the backlight power plug, it is between the cn1401 plug and the fet q1401. the resistor in question was damaged, just change it.	Check the resistor in question and replace it if its characteristics have replaced.	EC
SAMSUNG	UN48H4203AG	Connect everything else without image	Defect was cd10 on the vcon changed it was just removed		<small>This email address is being protected from spambots. You need JavaScript enabled to view it.</small>
SAMSUNG	CL21A551ML	White image with retraction line and cushion effect	200v track starting between d407 and j252		MEO-ELETRÔNICO Cajupiranga (RN)
SAMSUNG	LT22A550 T22A550	It works but the back light doesn't come on. replacement of the ICD801, DD850, QD850 on the power supply PCI.	Icd801-oz9998bng , dd850-sr210 , qd850 10l01 (mosfet).	It worked perfectly after replacing the components described. I used the 15l01 instead of the 10l01 and it worked very well. This TV monitor is using the bn44-00448b or bn98-03094b board.	Ferrarini
SAMSUNG	LN32A450C1	Loses image after a few seconds leaving only the sound	Lamps turn off after a while due to protection being armed	Put a 10k resistor from pin 15 to the ground of the oz9966sn on the inverter board!	Lucas
SAMSUNG	PL51F4000	Dead sign board	Diodo zener do +b 3,3v em curto	Replace zener d901 prox power supply connector	edmilsompimentel
SAMSUNG	PL51F4000	Sometimes it called, sometimes it took a long time to call	3v3 that feeds the eprom with 4v5v, right, it would be 3.3v	Replace the regulator IC on the IC806 signal PCI.	edmilsompimentel
SAMSUNG	32D5500	12 volts pulsating	Fet qm855, put a 120k resistor from gate to ground	Rafael's tip	HP ELETRONICA
SAMSUNG	32D4000	12 volts pulsating	Cm855 fet, place a 120k resistor from gate to ground		HP ELETRONICA
SAMSUNG	UN50TU8000G	Turns on, lights up LED bus and turns off, no image, stays in this loop	I saw several videos trying to isolate the cause with the famous tape on the flat, that procedure of searching until you find a point that releases the display short and the TV releases the image.	I couldn't do it that way, because the short was in the first left flat, that is, looking at the TV lying on the counter with the screen down, the flat that was preventing the TV from working was the first one on the left side. on the left side vcon board tsound is the test point "vgh", the track of this vgh that goes to this flat was cut and the TV worked perfectly without any scratches on the image, to make the cut easier the cut was made close to the r44 on the left side vcon board, please note Tsound you have the vgh point test and the cut I made right after, that is, I will remove this vgh reference that goes to the first left flat...
