TV LG	42LE5500 eax61750103-0	Whistle switch doesn't light up black lite	replace transistor q8002 p1 near the power supply connector at the bottom	just replace transistor and hug	miguel estrela dalva
LG	21FU4RL MC-059C	The LED would light up, generate a high and turn off	After replacing several bad components, I tested the entire power supply, and finally I found transistor Q103 completely shorted, the transistor that feeds the varicap's 30volt line, I removed it, the TV remained the same	replaces the ic501, the TV was good thank GOD ----12/31/2024-----GOOD LUCK EVERYONE	Otacilio eletrônica G.G
LG	28MT49VF-PZ	Turns on stand by LED but doesn't do anything else, doesn't even blink	Ic404 ams1117 adj		Rdxk
LG	32LS3400 EAX6456502	FLASHING STANDBY	FOTOACOPLADOR	power supply BOARD PHOTOCOUPLER IC502 AND IC503 BOTH EL817	RIC TEC 1193096-7971
LG	CJ87	Connect the power supply board without the main board	In the cn901 connector, short-circuit AMP_CTRL and PFC_CTRL and from tsound solder 2 resistors, one of 470r that goes to GND and another of 330r that goes to the 5.1 volts of stand-by, after maintenance everything returns to normal.		dudutekk
LG	CJ87	turns on, but no sound	Zener diode zd908 (22 volts) and zd907 (16 volts) shorted, transistor q955 (2sc5344) shorted, you can use BC337 instead, but respecting the differences in the terminals and smd resistors r9A5 and r946, both 10r open.		dudutekk
LG	32LD460 42LD460 32LD420 42LD420	White picture, icons appear, but white.	Defect in the C.I regulator next to the flat connector, does not drain the c.i.	If different from 1.8, find the C.I IC601	ArnolTec
LG	50PN4500 50PH4700	Burning Ysus	Capacitors SMD and Ysus C415, C416, C417, C418	Remove these capacitors	GABSENS
LG PHILIPS AOC	43S5195 43S5295 43LJ5500 43PFG5813	Screen flickering lines on the screen	replace the display	I didn't find a cheap display, but I gave the budget based on one on the free market and it was approved, I'll leave the link for anyone who wants to buy it: External Link...	KICO
LG	32LJ600 Placa lt 66k EAX66874605	without power 121 volts screen	ic 601 MPS 1634 ou substito MPS 1731		Eletrosideral Sp
LG	32LH570B	Without 12v to provide an picture.	Defect in IC mp3378e in position IC601	replace the IC for an identical one	ArnolTec
LG	49LF5500	Bay stand LED flashing	SMD transistor on the side of the power supply connector on the main board	replace Q401 Q402 Q400	Fernando Nascimento
LG	47LF5500	Bay stand LED flashing	SMD transistor on the side of the power supply connector on the main board	replace Q401 Q402 Q400	Fernando Nascimento
LG	32LD420	Restarting	Retighten the terminal connectors connected to the power-on line wires	Note: start with the blue thread.	Medeiros Eletrônica Barbacena MG
LG	22LH20R	No picture	Disarmed IC protection IC301 With a 10k resistor pin 3 to GND	Disarmed IC301 R10K pin 3 to GND	Panther Tech
LG	42LN5400	Random off/on	Cap 1u500 has a 1688 cap with other good parameters	replace	Warley cesar
LG	14SB1	No sound.	Capacitor (C611 of 47uf 25v) of the ripple filter replaced. It is connected to terminal 1 of the CI LA42071 (IC601 - audio) and goes to GND.		Sígmar de Oliveira
LG	42LE5500	normal alloy but without backlight and ci 8005 heating	Shorted processor	I replaced the main board. It worked perfectly	Jhone eletronica
LG	42LF20FR	it doesn't turn on or standby, the secondary 5v supply was pulsing or low, when disconnecting pci main 5v returned to normal	Short circuit defect on PCI main IC 1001 = bd9130 responsible for 1.3v, you can remove the cause of the short and with a 1.3v power supply see if the rest of the TV works	After replace the ci, everything started working again.
