Make	Model	Symptom	Problem	Solution	By
LG	28LN500B	Tv completely dead, measuring the power supply input on the board on the homic scale is shorted.	Checking the board I found a shorted 10uf SMD capacitor c1112... replaced and problem resolved.		GR EletrOnica
LG	32LM3400	Image with black dots	I changed the tcon 6870-0370, I put the 32lv, it worked perfect but the image was reversed, I removed the r24 in the tcon and it was reversed, it was perfect.		Sylvox
LG	32LM3400	Image with black dots	I changed the tcon 6870-0370, I put the 32lv, it worked perfect but the image was reversed, I removed the r24 in the tcon and it was reversed, it was perfect.		Sylvox
LG	21FJ6RB M059A	On and off remains on standby.	Capacitor with oxidized legs or without capacitance. c409 of 220uf by 10v. note close to the +180v power harness	After changing the TV ok.	George Pontes
LG	47LH70YD H	Hdmi ports don't work	HDMI chip getting very hot, defective	IC601 Chip Replacement TDA9996HL/C1	Marcelo Rodrigues
LG	42PJ350	Power supply arms and then disarms	Transistor q-906 shorted.	Replace the same	Régis
LG	28MT49S	Doesn't start	10mf capacitor shorted near diode feeds leds	Replacement	EJ
LG	CJ87	Does not turn on or turns on from time to time	Defective x500 crystal	Replace the crystal with a 20mhz one soldering on pins 1 and 3, since the original has 4 pins or pads.	Fofao estância
LG	26LH20	Backlight disables after about 4 seconds	I noticed that it was only when tsound was no video signal.	But the solution was the same as that suggested by Fatec Electronics, that is, isolating tracks 2 and 3 of the flat connected to the p402 connector.	Chumbão
LG	32LG30R	TV turns on, but if it turns off it is very difficult to turn it on again.	Change the value of resistor r128 from 11k to 15kΩ		Eletrônica Marinho BH
LG	50PN4500	No image, with sound - it wasn't the open 22r resistor near the t201 - underneath the heatsink tsound was a burned smd capacitor, and it burned the 2 fets 30f133, (igbt) which can be substituted for the fgd4536 used in samsung tvs (plasma )	Change two fets 30f133 = fdg4536 (samsung plasma)		VICTORINO
LG	32LM3400	Does not turn on, no stand by.	R506 changed from 75k to 50k	Replace with a 75k resistor.	Antoni Garcez
LG	42SL90QD	Turns on, but no image appears, nothing appears	Processor reflow or reballing	As already mentioned by colleagues on the forum, I reflowed the processor, that is, thermal blower at 450º for 3 minutes on the processor (without the heatsink)	Claudio Eckert
LG	14FK3RB MC059D	Normal turns on with an image without characters with a black band in the middle of the screen and after a few seconds the image keeps scrolling and shaking	D405	Swap without measuring the d405 and the TV will work normally. God be praised	Sinailson furtado
LG	21FU4RLG	Low power supply +b giving only 87v.	C847 1uf for 250v It is important to test the ESR before changing.	Replace c847. (tec. edfersom, varjota-ce)	Edfersom
LG	RP29CC26 RP29CC26	Image closed on the sides 3cm	Resolds part of fly e d401 cold welds	Resolds part of fly e d401 cold welds	XLA ELETRONICA
LG	43LJ	Lower backlight voltage.	Change r801 to 2r2, voltage drops from 65.5v to 61.8v.		electronicssupplyparts - Gramado/RS
LG	MCT-704 SOM LG	Does not turn on, primary power supply does not oscillate	Capacitor c931 of 10 nano polyester with zero capacitance and c986 of 1000mf 10v practically zero as well	Device turned on normally again	jorge.tec
LG	42LC4R	Turn on the backlight and then turn off the audio	On the icu301, place a 10k resistor on pin14 to ground	Putting r10k to ground disables the IC protection and abs works normally.	eletronica formosa
LG	42LC4R	Power supply has 5v but does not turn on the stand by	Changed 10k r208 resistor	This resistor is at the photo pc130 output	eletronica formosa
