Make	Model	Symptom	Problem	Solution	By
LG	42LD460	Does not turn on. does not even light up on standby. good power supply	Remove the sw1001 touch key from the main board..and clean the board well..wsound the key is..leave it without the key. because she is driving.		fernando
LG	28MT	Increase the volume alone	Follow pin 2 of the connector that goes to the function keyboard, and remove the first resistor that goes to ground		Rodrigo cofferi
LG	32LK450 42LK450	Does not tune channels	Falta 5v no +b do seletronic	R466 r467 prox. ic406	DsInfo&Eletro
LG	49LJ5550	Merged image crashing with 1 line going up	In my case, I just changed the tcom and went for the hug		Eletrônica moura trindade
LG	26LD330	No audio	Factory reset		Eletrônica power saquaçú
LG	32LS3400	Doesn't start. 3.5v low voltage	Q502 transistor smd ktn2222as		Rafiuski86
LG	42LG30R 32LG30R	Turns off by itself, sometimes it doesn't turn on, sometimes it gets a greenish screen, it makes noise from the speaker and turns off.	It may be caused by several possible problems, carry out the following procedure to resolve and avoid a possible return.	Check the power supply and inverter board for swollen capacitors and replace them. Remove the power supply components: c108, zd111 and zd112. Also at the power supply, replace the 11k resistor r128 with a 15k or 18k one. On the main board, replace the SMD electrolytic capacitors that are close to the processor and RAM memory with values of 100μFx16v and 10μFx16v. Clean the main board well on both sides with thinner or isopropyl. resolder all fets, transformers and heatsinks on the power supply	GABSENS

LG	24TL520S-PZ	Replacing the mainboard and getting a service mode message.	Main board nova	The original command does not resolve. Perform the operation with the an-mr18ba model command (https://www.factoryreset.tv/reset/lg-24tl520s-pu): https://spareparts.pt/pt/produtos/comando-smart-magico-tv- lg-an-mr18ba?gclid=cjwkcajw6raybhb7eiwabge5krp2sd2l4zxgbekl-nz3knoc5otlhw_6ddmhmrjvzjlmw67wsbnk_xoc41oqavd_bwe	Neu
LG	M228WA M228WA	Does not turn on, no standby.	Zd101 changed, it was not shorted, but not behaving as a diode.	Changing the zd101, which when measuring on the diode scale leads on both sides, and measuring low resistance, replace with 1n4746 18v zener diode, the pwm vdd appears again and the monitor is ok.

LG	32LY340H	Doesn't start. only stand by LED on	Heat bgas with thermal gun		Eletrônica Pauly
LG	LM-U550A	Turns on but no sound comes out, the +32v power supply doesn't work	Change photo coupler pc901, tl431 ic949 and place a 1mega resistor on pins 1 and 2 of the photo coupler		Rodrigo cofferi
LG	42LC4R	Everything works except the backlight. lamps do not light.	On the power supply/inverter, check the 1uf/400v capacitor in series with the lamp inverter transformer.	Replace the capacitor.	NelsinhoPira
LG	50UK6510PSF	Reduce LED current,	Current between 420ma drops to 370ma, voltage also drops from peak 140v to 139v, operation 145v to 142.7	Remove the smd resistor r809, to reduce it further you have to replace theΩ of this line from 1.6Ω to 2Ω or more	lucian oliveira 61991271532 DIGITAL TECH
LG	50UK6510PSF	Blue image	LEDs with broken phosphor layer due to heat, replace LED bars		lucian oliveira 61991271532 DIGITAL TECH
LG	32LN570B-SA	All power supply output voltages changed.	If r205 changes below the nominal value, the output voltages will lower their values. in this case r205/120k was measuring 95k.	Replace r205 with correct value. stabilized power supply and TV	IZEletrônica
