LG	49LJ5500	Wifi off / can't find wifi	Update software over lan network	Success to all	marigwr
LG	60PA6550	Turning off after a while	Complete resoldering of PCBs y, z and power supply was carried out. The problem was resolved and another one appeared. 1 fixed horizontal line on the screen.	Flat bμFfet cleaner next to the line. not resolved. cleaning of the 3 flats close to the line was carried out and it was resolved. good luck !
LG	21FU1LR CW81A	Replace	R 844 of 4.7k	Replace	Mauro Mascarenha Tel. (88) 981422821
LG	60UM	Sometimes it cuts the image and only audio remains! but always with the LEDs on! on the t-com board, if the FET300 IC heats up, it releases 17v and the image comes back, sometimes shaking the right side, change the t-com	Sometimes with an image, sometimes not! but always with the LEDs on! changing the t-com		Rodrigo cofferi
LG	47LA6200	Blacklight comes on but no characters - no image - 12 volts were not enough on the tcon	Capacitor on main board - c2435 shorted killing the 12 volt line.		George Luís
LG	MCD212	League without sound	After changing the output and some damaged resistors, the 34v voltage from the power supply was not appearing, until I replaced the ic902 with a c1845 transistor and everything was beautiful.		Eletronicazetec
LG	21FU4RL	Does not turn on LED turns on and off does not generate high	R840 shorted	Just replace and run for the hug	Ammalho de Sousa Silva Filho
LG	CM4350	It gives sound for 1s and goes into protection mode.	Pc903	Changing the photo coupler pc903	Ogeid
LG	CM4340	Inoperative, no secondary voltages.	Zd901 (zj27d) diodo zener 27 volts 500 mw; zd902 (zdgj6.2d) diodo zener 6,2 volts 500 mw; pc901 (pc817); ic901 (ice3br4765jz)		Eletrônica Barbato
LG	CM5660 SOM LG	Stereo, turns on but after a few seconds it displays the d-protect message without audio.	Zener diode with momentenclature on the zd912 board. 20v short beeping on both sides. You have to remove one side to test correctly.	Replace 20v zener diode. zd912. Sometimes the MOSFET goes with it too. if you replace it and don't decide to replace it.	JC Eletrônica Cícero
LG	CJ87	Without the standby power supply working.	Tip by severe mailson, zd902 diode.	Replace the same.
LG	42CS460	It doesn't turn on, the power supply is ok, but when it connects to the main one, it kills the power supply voltages.	Short on 24 volt line	C523 shorted, close to the audio ic on the main.	LABOTRON
LG	60UM7270PSA	Blue image with normal characters	Defective LEDs	Changing the LED bars and reducing the LED current, removing r801 and r809	George Luís
LG	60UM7270PSA	Blue image with normal characters	Defective LEDs	Changing the LED bars and reducing the LED current, removing r801 and r809	George Luís
LG	32LB3RS 0000	Stand-by ok mas ñ liga	C204 c205	Replace without testing! good luck!	Jhone eletronica
LG	CM9530	Cutting audio and turning off	Irs changed	Check all irs if it is generating pwm replace the defective ones along with the diodes around them	Geovane
LG	RP 14CB MC-059A	Vertical closed	Cold solder on ic803 7805.	Solve ic803	MARCONES DE ARARIPINA-PE
LG	OK55	Doesn't start	Short in the power supply in the zd902 diode, it is close to the photo coupler pc901		Mateus Borges
LG	LGP32-13PL1	Does not turn on, fuse blown, short q101	After q101 replaced, burned ic101, c102, q101, r113, fuse. has been replaced/tested ic101, c102,q101, r113, r106. Then I had 3.3vlt, but the TV wouldn't turn on and a buzzing sound was heard when pressing the power button and the 3.3vlt dropped to 1.x vlt. components d103, f100, r104, r105, r106, r107, r10, r109, r110, r111, r112 were replaced/confirmed and it worked flawlessly. Attention, if r106 is open, q101 burns immediately after energizing the power supply. the r112 (it was open), was the reason why the power supply made the buzzing sound		gccp
LG	(42),(32)(26)LH20 42LH20R	No audio	Capacitor 10-16v c866 e c809 .		Japajpeg
