LG	32LD350	Noise on the tcon board appears to be at the power supply.	I washed the board and it was fine.		Eletronica EASI
LG	OM4560	Nothing turned on, tsound were 20 volts at the power supply output but when I pressed the button to turn on the power supply it dropped to 12v	Cause of the defect was a q920 transitor close to the oscillator ci switch without measuring		Eletrônica DIGISOUND
LG	32LK450	Performs functions alone (call AV, menu, change channels, turn on alone...)	Touch keyboard. I couldn't find it to buy.	I disabled the keyboard by disconnecting pins 4 and 5 of the p2401 connector on the main one. Now it works but only for control.	Mau3000
LG	RAD226B	Display and stand bay flashing	Shorted audio output (tas5612a)		Tecmaps
LG	21FJ6RB MC - 059A	Black band with white border on the inside or (lower) part of the screen	R - 313 of 47k changed or opened	Replace	Mauro Mascarenha Tel. (88) 981422821 Parazinho - ce
LG	50PK550	It doesn't turn on, without vs, without the power supply it doesn't turn on	The two pfc relays were not activated	Replace npn smd transistors q705 and q706	LOOPTEL
LG	42LB5600	Every time it turns off it goes back to the initial configuration, to choose language, search for channels, region, etc.	I don't know if it's related but it came with burned out LEDs too. it may have had a power surge and burned out the LEDs and corrupted the memory data	Swap or rewrite nand memory ic102	World TV - Sorocaba
LG	RP20CB20A	No audio at all from the speaker	R625 open next to the sound output		Eliel Magno
LG	32LH510B	Standby light on but not turning on	Ic 500 short		eletrônica newtec
LG	43UH6100	Image appears and turns off in a direct loop.	Low power supply. When turning off the LEDs, the TV remains on but with the power supply at 160 volts	C612 shorted	LABOTRON
LG	50PA4500	Burning q404 q403q402q401 due to changed vsc voltage	Cause r266 open check all line resistors		reginaldo.
LG	21FU6TL CW62E	Vertical closed with lack of synchronization in characters	R311 =30k open	The solution is to replace it	ELETRONICA EM CAEM
LG	42LB9RTA	No sound, just noise from the speakers.	C208 and c221 on the power supply board. Note: all power supply voltages are normal. exhausted capacitors	When replacing the TV it worked perfectly.	Real Eléctron Carvalhos MG
LG	55NANO75SQA	It wouldn't turn on, just the standby light on, power supply ok	Faulty main board	Changing the main board, I put it from another LG55uq801c0sb model, it worked great	Gilberto Costa

LG	RN9	Sound keeps failing	Mosfet in position q208 close to the sound output and the 12000hz crystal	This shit box doesn't have a complete schematic but I managed to solve it by putting a 2n7002bk-gp	ANDREI ELETROINFO
LG	47LM6700	LED TV stuttering and won't turn on	On the main board, I disconnected all 24 volt power supply at the main board input connector, the image appeared and sound. I found a shorted capacitor on the 24 volt line. I changed the capacitor and it works perfectly with sound.	Replace capacitor on the 24 volt line very close to the hdmi connectors.	Marcio
LG	22MA33D	Inoperative, no short on board	Capacitors 800 and 804 shorted	Replace the aforementioned capacitors	Gmedeiros
LG	42LG30R	Red LED turns off as if it was going to turn on and it doesn't turn on, power supply voltages are absent	Shorted transistors on the inverter, the fuse did not open, causing the 24v power supply to trip		davi.sls
