Make	Model	Symptom	Problem	Solution	By
LG	21FE85G MC59A	I'm sound	Eeprom	I tried everything, then I replaced the eepron and went for the hug	agildo andrade
LG	CM4630	Going crazy after a few minutes of operation changing functions alone	Touch keys and lines on the conductino board	Changing the keys and connecting the tracks directly with wire solved the problem	charlotniu
LG	RD136	I'm sound	When checking, tsound was no current in the sound output, a scan was carried out at the power supply and the zd905 zener diode was detected in short	Just replace the component.	Eletrônica Morais
LG	32LS3400	It doesn't turn on, stand by blinks off and tsound is no 24 and 12v.	Ci 101 sc1s311 and r106 of 47r open in power supply. reason for burning c 102 of 470pf (471) blown.	After changing the TV ok.	George Pontes
LG	50PB560B	TV works normally, only has sound and no image	Shorted capacitor on the ysus board (c205) near the transformer	Replace for the same	Eletrônica Bastos
LG	42LH35FD	Without image, sometimes with slow image and sound (thick voice, out of frequency) then everything freezes.	The xtal x201 glue damages the components around it, harming the oscillator.	Replace the replaced components l206, x201, c298, c299, r205, r208, c269 and r211. I hope I helped!	Julian C Braga
LG	32LD840	TV restarting continuously, sometimes it works for a few days	3.3 volt power supply goes down, I go back to 3 volts	Replace without measuring c804,805 and 815	NARDINHO ALFENAS
LG	32CS460	Turns off by itself	Turns off by itself		Eustáquio
LG	42LP560M 60LN549E 55LN549E 55LN541C 47LN549E 47LN541C 42LN549E 42LN541C 39LN549E 32LP560M 32LN549E 32LN541C	TV restarts, works fine for a while, turns off and turns on again	The problem arises due to problems connecting the voltage between the power supply and the MB or the TV detects a failure at 3.5v_st.	The problem is normally in the connection cable between the power supply and the board, check the connectors, fix the cable with "glue" or another means.	Constantino Palha
LG	32LF57 49LF51 49LH57 49UF64 49UH60	Faded blue image	This symptom appears due to the loss of silicone in the LEDs	Replace the LEDs/connection strips	Constantino Palha
LG	EAX55729302	Standby LED blinking, no image	Remover c848 (mlcc) capacitor (mb)		Constantino Palha
LG	EAX55729301	Standby LED blinking, no image	Remover c848 (mlcc) capacitor (mb)		Constantino Palha
LG	32LH30-UA EAX56738102	Standby LED blinking, no image	Remover c755 (mlcc) capacitor (mb)		Constantino Palha
LG	CM4420	Tsound is no sound, and over time it just turns off	12 volt power supply is missing	Replace without measuring the diode d921 and that's it, I hope I helped	Célio
LG	CP21Q22 MC997A	When plugging it into the socket, the LED turns on, it has b+ ok, it drops b+ and des. The LED obeys control but does not have 15 kz	Ic 02 sda com 4.5v scl com 4.5v ic 501 pin 12 scl2 com 0.25v sincronismo	Interrupted trail, redo with thread.	GDP2
LG	21FJ6RB	Vertical deflection with 40% opening with trapezoidal effect on the image showing convergence lines	Vertical reflection coil broken by oxidation measuring 21Ω, normal would be 11.9	I removed the coil locks and soldered the broken wires, the coil resistance normalized to 11.9Ω. You can also replace it with another of the same model	Sandrine Rogério monteiro Sanches
LG	42LD650	Red LED flashes slowly but does not turn on, and tsound is a buzzing sound on the main board	Cold solder on ci ic8001 and components below c8029, r8043	Heat area with flow to 350º	T.CUNHA
LG	19LV2500	Flashes standby and does not start, does not light up and turns off	Bga principal	After the reflow it worked normally. Cheap equipment, you can't charge a lot	trovarelli bauru
LG	21 CW81B	Vertical folding at the top	Resistor r301 =18k was changed to 25k.	Replace of the same.	Hiper eletrônica service (Maraial-PE)
LG	50PB650B	Tsound is no image	SMD diodes next year t201 trafo t201 na plate y-sus with cold solder	Resolder diodes and the transformer itself	Eletronicaaeb
