Make	Model	Symptom	Problem	Solution	By
LG	RP-21FE85G MC-059A	The LED doesn't turn on when you press the power button to start it, but it doesn't help and it overcharges the power supply capacitor!	Fly-back	Replace the fly-back 6174v-6016a without measuring and run for the hug!	Sinailson furtado
LG	32LS3400	Turns on but has no image. the black light turns on but tsound is no image..	After checking the voltages on the main board I saw that tsound was a lack of power on the BGA chip. cause of the defect ci402 this ci that regulates the voltage of 2.5v.. it was giving 0.12v.	Replace the 2.5v voltage regulator IC402 on the main board	Diego de Lima Costa Nova Timboteua Pará
LG	21FU4RL-L3	The LED lights up, but when you press the image button it gives the signal but the image does not come on	The LED lights up but the image does not appear		Ivan Francisco de Paula
LG	21FJ6RB	When plugging it into the socket, the LED would light up, but it wouldn't turn on with the control or the keyboard.	C11, c12 and a small crystal next to the two capacitors, close to the micro.	Replace of the three mentioned, TV was ok.	Rdontônio-Acre
LG	26 LX ER YP2632T	The green pilot light comes on, and the relay engages from time to time.	The power supply yp2632t has voltages 3.3v and 5v, and does not have the other voltages "33v, 24v, 18v, 12v and 6v"	After replacing all the electrolytics in the power supply, the same symptom remained. replaces polyester "c104 0.47μF 400vdc" ok it worked	Paulo Costa
LG	42LB5800 LJ46B	No image. audio only.	Many shorted LEDs and one open. to replace.	As a precaution, I lowered the current in the circuit. I removed the inverter resistors r817 and r818 (both 4r3). the measurements went from 212.8v and 91.6ma to 203.9v and 68.7ma.	Eletrônica R-Tec
LG	CM8350	Is demonstrated. with LG demo music.	Check and replace front panel switches		Ricardo silva (PA)
LG	32LH20R LP91A	When turning on lamps, it blinks and goes out.	T-con plate.	This TV doesn't turn on the backlight if you disconnect the LVDS cable, sound's a tip!	BRITO
LG	32LY340C	No image on the entire display. only one corner had an image.	Almost all LEDs shorted. only one worked.	I lowered the circuit current. I removed the inverter resistors r816 (8r2) and r817 (1r). the measurements went from 64v and 100ma to 62.5v and 76ma.	Eletrônica R-Tec
LG	49U6565	LED power supply changed	R804 of 10r	Replace r804 from 10r to 22r	Multimarcas/Acarí
LG	21FJ8 CW81B	B+ 78v led on, power b+ goes down, led turns off and on and b+ goes up to 110v	C 814 220uf/160v with 207mf killing the voltage of b+		GDP2
LG	50 PLASMA	Dull drizzling image	Open resistor	Resistor 0,22Ω placa ysus	adelcio
LG	RP20CB20A SC-023A	Audio and it took a while to respond to the keys	D23 em curto no pino 58 do ic 501 pino do scl	Replaces with a diode: 1n4148	LUCINALDO
LG	42LE4600	LED blinks stuck on white TV won't turn on	C204 ec205 both electrolytics 220nf 6v	Replace with 220nf 16v	Medeiros
LG	50PB690B	Distorted image and turning off	Power failure vs.	Changing the resistive network r902a to r905	GL Eletrônica
LG	CM4330	League for 30 seconds enter sprotectio	C726 curto.ao side ci audio	Replace it and it's zero again	George Eletrônica Milênio
LG	32LF20FR	TV doesn't turn on	Diode, capacitor and fuse blown.	Replace the diode d601, capacitor c600 (they are between the transformer and the high-voltage capacitors) and the fuse f100.	Darci Denzer
LG	W1943-PFV	LED lights up directly with rapid blinking and no image.	Voltage from 3.3v changed to 2.8v.	Replace capacitor c354 (220mf-16v), on the main board.	Roni Eletrônica
LG	32LB9RTA	Weak standby LED and 5v power supply with 2v or less	Changing the electrolytic capacitor c506 10x50 in the power supply primary		Resistronic resende
LG	42LY340C	No image. audio only.	LEDs short and open.	Replace short and open LEDs (3 in total). and I lowered the circuit current as it was the second repair on the same device. I removed the inverter resistors r817 and r818 (both 4r3) and added another one in series of 4r3 to the existing r816. getting 4r3 + 4r3 in r816. the measurements went from 142.4v and 91ma to 133.7v and 60ma.
