Make	Model	Symptom	Problem	Solution	By
SAMSUNG	UE55KU6100	Does not work, does not turn on standby LED	Voltage of 13v with +/- 9v. Defective solders on capacitors c245, c247, c248 and c280	Re-weld the affected lines
SAMSUNG	UE55H6200AW	Turns on, backlight comes on but tsound is no image.	Fault in the LCD panel, tsound is a short or leak in the panel capacitors.	Check all capacitors connected to the power supply line, especially the 22µf capacitor at the end of the line	ERP-ASSIST
SAMSUNG	UE32J5200	Image with poor colors without the possibility of adjustment	R5_gain in incorrect service menu with no possibility of correction	Rewrite memory 24c256	ERP-ASSIST
SAMSUNG	LT24B301EW	Stand-by light flashing, does not start	At power supply, 1200&microf/10v capacitor disabled		ERP-ASSIST
SAMSUNG	LE22C450E1	Doesn't start. led blinking	Capacitor shorted to the rf input		Pablo
SAMSUNG	S27F358FWU	No backlight	Check replace 60v 300ma sot-23 2n70002k
SAMSUNG	UE46F6320AW	Turns on and off, power supply goes into protection	By deactivating the protection (r bridge qs861), the power supply starts and does not turn off. LED strip failure		Pablo
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>
