Make	Model	Symptom	Problem	Solution	By
LG	29FG1RL CW62C	Image only at the top of the screen (4 fingers + -)	R566 4k7 aberto.		Ricardo Silva
LG	42LV3400	Does not come out of standby	I replaced the ci l6599d, however, the TV still didn't turn on. After researching, I realized that the l407 coil (on the main board next to the connector) had glue on top, disturbing the contact. After warming up the point, the TV worked normally.		NiloTech
LG	CM9530	Connect 5v giving 4.5v pin 1 ic700 check r7b2 under the board.	R7b2 was changed giving 49k	Replace the 5v and it's normal.	Eronaldo (erontec)
LG	21FJ8RL CW81B	Vertical closed	R311 30k	In my case I just replaced it and it resolved	SAM VIDEO SOM
LG	42LB5800	The screen's LED bus, stand bay, did not turn on, it blinked once 3 times, one quickly and 2 long.	An external voltage was injected onto the LED bus to see if tsound was anything burnt and everything was ok, at the output of the board voltages that feed the LEDs were present, the problem was in the connector that connects the lamps to the board, the cable was soldered directly on the board, it worked normally		Rodrigo Coelho
LG	50PT350B	Doesn't start	Short z sus board, replace shorted 30f124 transistors, in my case tsound were 2, it worked 100% just replace		reginaldo moronte,eletronica junior caldas novas
LG	21 POLEGADA ESTA SEM ETIQUETA	TV working normally when you turn on the DVD image shaking as if it were the video cable	4k7 resistor 512 measuring 5k	Replace r512	francisco
LG	32LE4600	TV with sound but no image, blacklight on	Its t-con board is on the main board itself, tsound was an integrated one getting too hot and I noticed a shorted smd 659 capacitor, I just removed it and the image came back.		Galileu Rocha
LG	42LD840	With image, and sound, but image in slow motion and sound also in slow motion.	Crystal 54,000 (x903) next to micro ic100	Replace of the same.	arock
LG	42LS3400	Break light on without image	T-com, c210 shorted.		MARIANO TV TÉCNICA BARCELONA
LG	PJ350	Does not turn on by hitting the relay	Photo coupler pc 901 and pc 902 replace		edinho eletronica matos
LG	26LG30R	Does not turn on, stand by LED is off	12v voltage varying, removing the connector that goes to the main, voltage stops varying..short in the main	Cc1104 shorted.	Maurilio
LG	LC42T17, 32LG30R	It takes 10 to 15 minutes to work. the power supply has voltages +5, +12 and +24	Check scaler board capacitors		Edson
LG	LN40R81B, 32LG30R, LC42T17	Scratches on the vertical and dark screen with normal sound.	Reballing on faulty t-con or ci		Edson
LG	20CD2R	Burning the horizontal output after about 15 minutes reduces the panel on the sides and the transistor shorts out. Note: normal power supply with 110 volts	Altered t 403 horizontal driver transformer	When replacing the TV it works perfectly.	REAL ELETRON CARVALHOS MG
LG	42LD460B	Blinking but not turning on	Q710 shorted and f501 open on the power supply board	I put 2sk3667 in place and it worked	Marcelo
LG	CM5660	Turns on everything works but tsound is no sound	Transistor q106 next l102 open.	Measure if tsound are 12 volts that power the ci tas5631, if the opu is missing, check if the 12 from the power supply is normal, if confirmed, check q106 which switches the 12v to the ci audio output	CONSOVI
LG	32LE5300	When turned on it gives a beep for approximately 3 seconds and then tsound is no image or sound signal	At power supply, pfc around 390 v. ok and standby voltage 3.5v. ok, but it doesn't have 12 and 24v voltages.	Ci smd l6599 defective, I replaced it and it solved the problem.	PATRICK ELETRÔNICA
LG	32LV5300	When turned on it gives a beep for approximately 3 seconds and then tsound is no image or sound signal	At power supply, pfc around 390 v. ok and standby voltage 3.5v. ok, but it doesn't have 12 and 24v voltages.	Ci smd l6599 defective, I replaced it and it solved the problem.	PATRICK ELETRÔNICA
LG	20CC25	Vertical folded on top	I changed capacitors and resistors around and nothing solved it, so by intuition I changed the memory and the defect was corrected.		Eliel Magno
