SAMSUNG	PL42B450	Does not turn on without stand by and without voltage on the main capacitors	Checked cold soldering on the dx807 transistor (it is on the right side of the power supply)	I solved him and the others. and the TV started working again without having to replace a single component	Macro Eletrônica DF
SAMSUNG	PN43H4000AG	Does not turn on and the standby LED is off	Change the photocouplers on the power supply board	D.a redetech
SAMSUNG	PN43H4000	Every stop, not even the LED lit up	Check all the jumpers because in my case they were all broken and also check under the heatsink as tsound are some hidden tsound ok good luck that was my case I fixed it and went to dim dim		eletronica publisom
SAMSUNG	UN40J5200	Black light flashing	LED bars shorted to the chassis		Mariano
SAMSUNG	UN50NU7100G	Reduce LED voltage	Change r 9201 and r9101 to 3.6Ω 2 watts	R9201 e r 9101	juci
SAMSUNG	UN32D5500 UN32D5500	Stand by LED blinking directly - if you disconnect the main PCI socket, the backlight comes on normally	LED protection transistor, QQ9101 PNP type SMD, with collector leakage for emitter	The qq9101 transistor is close to the LED socket, as it is a pnp type on smd it is difficult to find in scrap metal, I found one on a sound card. it worked perfectly.	RUBERVAL SBC
SAMSUNG	CL21C650MLMXZD	Turning off with rainbow effect with audio but no image	Faulty vertical output integrated circuit.		ELETRONICA NOSSA SENHORA APARECIDA
SAMSUNG	LN32A330J1 BN4100984A PLACA PRINCIPAL	Does not come out of standby does not turn on	Q1003 mosfet	I checked the 5 volt voltage at the power supply and it was normal. I checked the reset power detection circuit. the voltage was low at 3.3v on pin 3 of the ic1005 regulator, I replaced it and it didn't solve the problem. Following the line I verified that the voltage was coming from the q1003 ci mosfet 9933b pins 7 and 8, I replaced it and the solution was resolved, the voltage returned to normal and the TV turned on normally again.

SAMSUNG	UN40F6400	Customer said he used air to clean, probably resulting in cold welds	I resoldered the entire power supply board, I replaced the 2 capacitors next to the 390uf/25v power supply output, I placed 2 of 1000uf/25v	After all this I still needed to inject 13v into the power supply output after that the TV turned on and tsound were no more problems	Petrukio
SAMSUNG	CL 14C600KJM KSCB	LED blinked continuously, plus b with 50 volts.	The cause was the faulty dz 808=5v1.		Eletronica Melo-Boa Viagem-Ceara
