Make	Model	Symptom	Problem	Solution	By
LG	32LK330	12v at the power supply, reaches the board, but does not go to the tcon	Q409 on the main board, bottom, close to the lvds output	Replace of the same	Liutec
LG	43LH5150	TV doesn't turn on so it stays on standby	Check if tsound is a short in the capacitors c520 c523 c524, if the short continues, replace the ic 500 mp3378e		FABIO GUEDES
LG	MS3052R	Microwave turns off when starting	Place capacitors with higher capacitance on the control board, check door locks	Place capacitors with higher capacitance on the control board	Paraiso dos Consertos
LG	29FU1RL	Low power supply with 83v	Resistor r834 4k7 1/2w was faulty measuring 7k2	Replace with a 4k7 resistor	EDIVAN ELETRONICA
LG	42LN5700	Turns on without image, however the LEDs light up	Without the 12v that feeds the tcom	Transistor q2407 open on the main board, just replace it and good luck	PATRICK ELETRÔNICA
LG	L1740PQ	Does not turn on - power supply varying	I changed all the electrolytics, tl431 and photocoupler, it didn't solve it, it was the ci fan7601	You fan7601	Pardal - X
LG	29LN459M	Shorted board	Capacitor c718 smd		Eletrônica Cecé. Brumadinho MG
LG	32LB620B	When plugging the TV into the socket, the standby LED would come on and go out immediately, the power supply had all voltages and the TV would not turn on.	MOSFET transistor Q405 on the main board, in parallel with the capacitor C427 measuring 12V on both terminals. Replaced the MOSFET transistor and the TV started working again.	Substituir transistor mosfet q405.	Manoel Damião
LG	14FK3RB MC059D	Does not turn on or light up when in bay	The cause was u photo coupler and dz801 closed	Replace both the dz801 and the photo coupler	Silvan dos santos
LG	TV 32PC5RV PS7231/1	Standby LED lights up green, takes 10 seconds and returns to red	Replace transistor q951 emcurto 9n25c e c904 replace	Shorted transistor and replace the c without testing	Simiao machado
LG	24MN33D-PS	TV didn't even turn on or stand-by	In my case smd capacitor on pci shorted	Replace the capacitor in position c804	Airton Filgueira
LG	RP21FE85G	Turns on the relay and turns off, goes to protection	Open resistor fr403 that goes to +b of the flyback		aquiles
LG	32LD420	Dark screen, normal sound	Voltage on capacitor c659 low, normal is 8v	Leaky capacitor c619, l604 and q409 burnt below the board. When replacing components, the IC600's voltages returned to normal. If you don't have the q409 to replace, make a jumper between the drain and power supply.	Eletrônica JJ
LG	32LY340C	No audio; Marcos Melo 8817	Bad sound output tas5733 ;marcos melo 8817 cascavel ce	Replace sound output tas5733; marcos melo 8817	MARCOS MELO
LG	60LV5860	The LEDs are blinking	Cap c801 and c805 changed	Replace the caps	ENGETRONICA
LG	50PQ30R	When turning on the TV, the power supply keeps hitting the relay.	The defect is on the power supply board: (5v shorted power supply diode)	Replace the diode (d352 usb3200) this is next to the transformer (t301)	AGILDO MENDES (MENDES ELETRONICA)
LG	47LW5700	Normal power supply voltage LED lights up and goes out slowly without turning on.	Processor with cold solder, heat with station.		Mailson severo
LG	50LN5400	Turns on the LG logo and turns it off	The apparent cause was shorted LEDs, but after changing the TV the LEDs turned on and tsound was no image. tsound was an open fuse in the 2 amp t-con	In addition to changing the LEDs. replace the 2a fuse in the t-con	flavio
LG	32LH515B	Doesn't start	Smd transistor d2922 position q501	Changing the fet smd d2922 transistor, in my case it was just this part	MULT INFORMÁTICA E ELETRÔNICA
LG	40LF6350	Sometimes it calls, sometimes it doesn't call	Q103 a fet channel n 04n60		Latual
