LG	14SB1RB	Low power supply 95 volts	Open resistance r844 - 4k7		NENO DO ERYOM
LG	50PB650B	No image with sound	D405 and c204	Replace components	E cobra
LG	32LD350	Turning off after a few minutes	A lamp without turning on	Changing the lamp	ON-PLAY ELETRONICA
LG	42LB6200 LJ43B	LED bar doesn't light up	Shorted LED or LEDs	Replace leds	Felipe Tales
LG	42SL90QD	I'm sound.	TV without sound, but with normal image. the digital audio output was off. all normal voltages.	I heated the base of the plate to 100ºC and reflowed it with a blower at 310ºC for 10 seconds. problem solved!	Rui
LG	CM4320	Input fuse blowing	Q902 e fusivel	Replace	eletronica sto ant rj bahia
LG	21FJ6RB	Weak image without brightness	Diodo d502 do abl	Replace for a 1n4148	Marcleo
LG	42LD460	When it turns on, the screen blinks and turns off, and the standby light blinks.	The first test to do is to force the power supply to turn on. make a jumper between the p-dim, a-dim, inv on/off, power on pins with a 100Ω resistor at 3.5v. If the back light lights up normally, the defect is in the main.	Replace the 100μF input capacitors. c401, c402	Henrique
LG	20CC25 MC059	Power supply pulsing and low with whistle pit pit pit if you turn off the fr403 the tension normalizes	Flayback replace		eletronica sto ant rj bahia
LG	42LK450	Does not turn on an off LED, power supply completely without even a voltage at the output.	R509 smd203	Altered or open 20k smd resistor r509 is next to the zd501 and connects to pin 6 of the ic501 str w6053n.	Daniel Freitas
LG	CM 4340	Won't turn on without 5v voltage	Zd901 27v	Replace it for another one even though the multimeter works fine.	Henrique
LG	49LB5500	The TV would work for a few minutes and turn off. The standby LED would blink quickly	100k smd resistor position r125 changed. close to two smd mosfets of the power supply that is underneath the power supply board
LG	21SA1RL CW81B	E/w	Check q405(k2941), r455(10k), l401 l401, zd403, d402 and d404	Replace burned components after check	Prem Shankar Singh
LG	21FJ8RL	Tv arms and disarms	Q16 e r301	Replace it with another and run to another	Antonio Carlos (Eletrônica Renascer)
LG	32LD650	When pressing the power button, the LED starts flashing. tensions ok.	Bga	The reflow was done and it started working normally again. but it is recommended to do the reballing so that the problem does not return.	croclaro
LG	20CB20A SC23A	Sometimes it would call, sometimes it wouldn't and when it did, it would appear with a horizontally reduced picture	Low voltage in the secondary of + b cap 814 of 47 by 160v exhausted	Replace and run to the hug God is faithful	eletronica sto ant rj bahia
LG	RP-20CC25	Does not light up stand by	After testing the secondary power supply, I discovered that tsound was a leak caused by the capacitor (c813) 102/2kv, killing the secondary voltage.	Capacitor removal or replacement (c813)	Carlos Alberto (Eletrônica Baturité)
LG	32LG30R	Turning on and off with noise	Capacitors on pci	Replace the capacitors on the main board: 875,879 of 10mf/16v and the cap: 1128 of 100mf/16v	flavio
LG	FLATRON L1740PQ	Red standby LED kept flashing, but monitor did not turn on.	Problem in power supply aip-0108. voltage below nominal and oscillating. problem capacitors.	Even though tsound was no visual mark, the capacitors were bad. Replace the electrolytic capacitors on the power supply board (c202 c203 c204 c205 c206 c207). As a precaution, I replaced capacitors c105 and c103.	Jonatas Dias
LG	CM4440	Does not turn on display...rarely works (cold) 3 seconds (turns off)	Ic501 ...with a magnifying glass or microscope, look over the ic and look for cracks or holes	Replace board, ic501 in operation, it already works hot (I added a decipher)	Alextecnico
