LG	40LV3500 L*01U	Inoperative, power supply damaged.	Diodes d501~d504 (1n4007) short circuited + fuse f101 open.	Replace all 1n4007 diodes and the 3.15a 250v fuse	leitemarcellus
LG	L203WT-BX	Monitor turns on and turns off after a few seconds, you can see that one of the lamp transformers heats up slightly.	Junction of the transformer wires with the lamp terminals charred by heat or poor contact.	Dismantle the entire screen, clean the lamp terminals well and reconnect. if possible, isolate with natural curing silicone (not acetic).	ASSOLINI
LG	21FJ6RB	Lg tv black bands on the sides without rf signal with retrace lines av works with blue band in the center	Memory	Replace the same	Adrianosecreta
LG	29FS4RL	It doesn't work without + b just knocks the relay	Photo coupler		DANIEL SOLÂNEA PB
LG	21FB32BRS RP 21FB32	LED on, press key, start, oscillate and cut off	Flay bek	Just replace and run for joy	eletronica martins ubatuba
LG	42LG60FR	Catching fire in the power supply capacitor c 700 220k x 450v	C 700 220k x 450v	220k x 450 v	ELETRONICA MAURI JUNIOR
LG	32LD420	Screen flashes 3 to 4 times and turns off	Diodo zener com fuga d512 15v		Alvaro (prolar)
LG	CP-20B85	It doesn't oscillate, it just turns on the LED.	C406 100uf 16v dia de ze dias	Replace	EletroClaudio Aguas Belas
LG	CP20B85	Lack of contrast.	D=502 open	Replace for a 1n 4148 and blz	ELETRONICA MEDEIROS
LG	21FU1RLG	Does not tune the channels.	30 volts of tuning voltage were missing. the resistor 114 (30k) was open, I replaced it and everything was ok.		valmirgold
LG	RP-20CC25	STBY LED goes out, normal sound on all channels and normal secondary voltages, but the horizontal one does not start.	Cold solder between the metal ring used to reinforce the solder on terminal 1 of the flyback and horizontal output collector.	A little tip: this cold solder was invisible even with the magnifying glass. I solved it as I usually do with this type of crack: preferably at night, turn off all the lights in the workshop and lightly twist the plate, a small spark should appear, mark the spark point and turn on the lights and redo the welding, it's a shot and fall. I delete them all	Altevir Lima/ Valparaíso Eletrônica/ PA
LG	21FJ6RB	This TV gave me a lot of trouble, it arrived with a burnt horizontal outlet, I replaced the horizontal outlet and the TV didn't work, it turned on and then came apart, I replaced everything that was part and it didn't solve it, after a lot of patience I discovered the defect was a 1k pressure resistance r842 near the transformer.	1k precision resistor position r842		Diego lima nova timboteua
LG	21 FU1RL L3	It takes a long time to turn on and when it does turn on it has a black stripe at the bottom.	C307 and c311 with low capacitance.	Replace c307 and c311.	Rondinele
LG	20CC25	White screen with retrace	Ic-501 with the rgb outputs with voltage above normal, then just change d-502 which was leaking for the contrast to act normally. hug		jorge fontes
LG	T730SH	Monitor turned on but had little brightness, to appear the image you had to enlarge the screen	C346 of 103x2kv little changed and ic303 lm2476tb	I replaced the c346 and the image improved a little, but with little brightness and the image flickering. I replaced the ic303 and it immediately resolved the problem of image flickering and low brightness.	RICARDO MARQUES
