LG	HT 503SH	Turns off by itself in seconds	I noticed that the DVD mechanics wouldn't open	Reflow in the processor when the mechanics are low	Fer
LG	32LS3400	As x doesn't connect,	If you turn off the keyboard and it's fine, it's because the keyboard is conducting.	Disconnect orange and red wires from the keyboard. This eliminates the keyboard. working only by remote control	oskarala
LG	32LS3400	Does not turn on nor does the stnd by LED light up	R 506 changed from 750k to 50k	Replace the same	jcgiantomaso
LG	CM4520	No sound comes out of the speakers, the cooler keeps oscillating and after about 2 minutes +or- it turns off	Tsound is no pvdd voltage, when turned on it reaches 30v and then drops.	PC903 photocoupler oxidized and broke.	Lucas
LG	32LS3500	It only has the +b 3.5v, but the 12v and 24v ones are inoperative.	It appears to be a defect in the power supply's ci l6599ad, but 24v line with short in c smd next ci audio amp	More repair tips on YouTube channel direct to the defect	BRUSKE
LG	49UJ5654	TV flashes stand by but doesn't turn on	Capacitor s.d. shorted on the wifi card. (no cap position information)	Replace the capacitor or replace the board.	Washington ELETROWASH SOLUÇÕES
LG	14SB1RB	TV turns on with normal video, when inserting video signal via RCA, synchronization is lost	Changed resistor r512.	Changing the resistor and resoldering the board.	Washington ELETROWASH SOLUÇÕES
LG	32LK615B LA84J	Doesn't start. no signal.	Replacing the main board. I lowered the inverter current to avoid return.	Added a 0r68 resistor to r816. the measurements were 25.4v and 662ma, with back light at 100%, for 24v and 427ma.	Eletrônica R-Tec
LG	42PJ250 PJ	Blurred image	Coil l1 zsus cold welding	Solder l1 zsus	Adao o gatao
LG	40LF6350	League without image	LEDs burnt out, the LEDis were repaired, but you have to change the whole kit	Replace the LEDs and reduce the voltage by changing the 3r2 resistor r816 for 8rde 2w, the voltage from 197v dropped to 181v.	ELETRONICA JUNIOR BELEM
LG	50PB650B	With sound and without image	When carrying out the necessary checks, I noticed the lack of 18v voltage on the zsus board.	When inspecting the ysus board, we noticed that the 18v voltage comes from this board, next to the two photo aclopad you will find the capacitor c204 (150μF/35v), being shorted it causes this defect when changing the TV it returned to normal.
