Make	Model	Symptom	Problem	Solution	By
LG	32LK330	Completely inoperative, tsound was no 3.5v stand by voltage	R 519 open	Replace 1m resistor	Eletrônica JJ
LG	47SL90QD	With image without sound or with sound without image	Bga	Reballing paid off. The expensive used plate was replaced and returned within 1 month, solution to return to the customer. TV very old headache and damage. trash	Marcelo2507
LG	32PC5RV	Sometimes the video disappears, only the audio remains, it seems to be intermittent	All voltages are normal, defect in the main PCI; replace it.		Thiago MC Jaú
LG	47LA6130	Dark image lights up LEDs	Replace t-con plate original code 6870c-0444a for 6870c-0452a	Original tcon board code 6870c-0444a after testing a similar one but no image or image without resolution was found compatible tcon board code 6870c-0452a	iran alves
LG	21FI1RL	Turns on and off, standby turns off	R816 open		Rogerio eletrônica
LG	47LE5300	Doesn't start	Check 3.5 volt power supply. replace without measuring caps 18×50 by 22×50 and the 2 photo couplers		Jocimar
LG	32LH20R	Turns on, stays on for about 5 minutes, starts to make clicking noises from the speakers and turns off, remaining in standby mode.	Ci 1007 smd the size of a bc near the sound output		Ariel Santos
LG	CM4350	Completely erased without the 5.6 votes from the power supply	Burst resistor, open in the primary power supply r 903 of 0.75Ω		Galileu Rocha
LG	22LG30R	Sometimes it turns on, sometimes it doesn't. Blue LED lights up, does not respond to any command, does not turn on back light.	Check voltages on ic 1000. 3.3v line. Normal case, when connecting pin 7 IC 1002 tsound must be 3.3v. If you don't have this voltage, check the 3.3v line r1009 (0Ω). this said which was changed to 300Ω.	Check, replace r 1009	arock
LG	42LB9RTA	Relay knocking, tripping, crazy.	R1030 (0Ω jumper) opening, on the bottom of the main board near pin 2 of the p1000 connector.	Make jumper with wire.	Dudutekk
LG	32LS3500	TV turns on, but with backlight off.	Power supply, defect.	Replace faulty ic101 l6599.	RNSPTEC
LG	FLATRON M228WA-BM	Does not turn on, no output voltage at the power supply.	Zd101 shorted.	Replace the zener diode and monitor turned on again.	TECNOBRU SBC
LG	FLATRON M228WA-BM	Does not turn on, no output voltage at the power supply.	Ci ice3bs02 (u101) changed.	Replaced the u101 and the monitor turned on again.	TECNOBRU SBC
LG	32LH570B	Replace	Smd capacitor c2306, approx. shorted to ic8100	Replace	Clagel
LG	M2431D	Changing channels and turning it off by itself	Problems with touch panel. a lot of oxidation even after cleaning the defect remained.	It was necessary to remove the keyboard control integrated, maintaining only operation via cr.	Jefferson
LG	32LK330	Sometimes when it turns on it comes with an image. hour without image. normal sound! and voltage that powers the tcom board varies downwards, remaining between 6.5 and 10 volts when normal is 12 volts	Precision resistor. r209, from 9k1		Nunes
LG	CM4420	Sound turns on normally but no audio	Oxidized plate and corrosion on the pin of the parts	In my case it was the PC903 photo coupler and the FB 902 coil, the pins were rusty, this power supply generates the power supply for the amplifier ok	Galileu Rocha
LG	37LD460	The standby LED lights up, when you press the power button the LED flashes and the power supply and main board produce some noise.	C401 and c402 of 100uf x 16v on the main board close to the power connector.	Replace components without measuring.
