Make	Model	Symptom	Problem	Solution	By
LG	29FS4 CW62C	Burning strw6556a, relay knocking, led goes out.	R 801 of 36k changed with 70k	R of 5 cores la, az, pr, vm e marr. prune by the,az,the.	GDP2
LG	49SJ8000	Crashing, slowness, wifi not connecting, bluetooth failing and smart magic crashing	Wifi plate	Do resoldering with solder paste, and cleaning the adapter that connects the flet to the board, the MTU has bad contact	Maroni
LG	32LB9RTA	Inoperative without standby	C506 10uf/50v	Replace the c506 primary power supply	MARCELO RODRIGO QUINELATTO
LG	32LB9RTA	Does not turn on, stuck on the green and red LED	Capacitors c204 and c205 were found on the power supply board, they were replaced but did not solve the problem.	After observations and tests, I found the capacitors c1026, c1001, c1115, c1187, c1108, 470μFx16v aluminum capacitors to be defective, replacing them resolved the problem	Mitzko eletronica
LG	42LM3400	Turning off	Resolder the transistors q 400,401,402,403,405 and ic408,409 on the main board close to the power supply connector		Assistec digital castanhal Pará
LG	32LY340C	I'm sound	Remove q5600 near the sound output. Tsound will be moments when the sound will appear and then remain silent, tsound must be about 3v on the middle pin of this transistor, after it is removed or in normal operation		fabiusmax
LG	29MN33D-PS	Backlight flickering	At first you think it's a defective LED, in my case it was cold welding on the d1103 diode	Resoldar diodo d1103	Gaera
LG	50PN4500	No image, with some pixels on the screen	Ysus card, just change it and run to receive the money		Cabeça
LG	49UJ6565	Image shaking, reddish and with horizontal lines on the screen (and also a bluish background, LED defect)	Bluish defect, the bottom is LED, only with replacement. To solve the problem of horizontal lines and reddish image shaking, only by changing the main board, but I reduced it a lot, practically imperceptible, I put duct tape on the lines of the lvds connector on the screen, lighter blue connector, the one on the right, on the side of the main board, start by covering the lines from left to right, you can cover about 8 to 10 lines		Claudio Eckert
LG	21FJ8RL	Turns on the LED and turns it on again	Even removing the protection transistor, it didn't oscillate in my case, I just had to change c828 47 /10 v	Replace c 828	Lincam Bezerra
LG	32LF20FR	No sound. audio signal ok.	Resolder the ic600 and its peripherals or replace the ic600 and c600 c609 and c604.		samuel leite
LG	32LD350	The TV didn't work, tsound was no signal on the TV.	Power supply did not have the 3.3v voltage to power the main board.	Next to the input rectifier bridge I found the 1mega "brown black green" r19 was open when replacing the TV and it started working normally again.	Rivaldo Lira
LG	RP20CC97	TV turns on normally, but image closed from the middle down and open top with lines of retraces	R305= 12k open	Replaced and resolved	Eletrônica Renascer (Boa Vista do Gurupi-Ma)
LG	42PG20R	Turns on, with sound and without image	Capacitor c515 smd on the buffer board broken, underneath it was charred	Replace c515, and remove all carbonization	HC Eletrônica Guaíba
LG	CP 29H90P	Vertically jagged blurred image	Image without definition		TecniTécnico Edivaldo Miranda Silva - Dangra Eletronica
LG	42LG30R ?	Turns on and within a few minutes turns off or locks the keyboard.	C 875 and c879 on the main board of 10 micro by 16 volts	Swap c875 and c879 on the main board.	This email address is being protected from spambots. You need JavaScript enabled to view it.
LG	MS3052RA	Restarting all the time	D103 just replace without testing!!!
LG	32LD350	Does not turn on, kills 3.5v	C457,c459-next to ic405-induces that c405 is leaky.		JORGE LIMA
LG	32LN570B PCB:EAX65284601(1.0)	Inoperative, not even the stanby led would light up	Shorted power supply	Blown fuse, mdf11n65b mosfet leaking position q101 leaking, capacitor in cut 331k 1kv position c102 were replaced	JEAN LORENZ
LG	29FS4RL-1 CW62A	Secondary power supply with 50v. pulsing arms the relay.	Changed the r 801 back to normal	Grateful fig	Sandes
