Make	Model	Symptom	Problem	Solution	By
LG	43LH5150 LJ67A	Backlight does not turn on	Before giving a quote for the LED panel, check diode d500 on the main board 3cm close to the connector for the wires that go to the backlight, between square coil (l501) and capacitor c504 (33/100v). this diode shorts out: code sr210.....I put an sb5200 diode...it worked...	D500 replace	MIGUELTV
LG	26LC7R	Turning on with backlight off	24v fuse on inverter board	Fuse at the input showed 24v and at the output, only 21 or less than 24 came out, replaced it and the backlight came on, replace all the capacitors in the power supply, as the ones that came in sound were all blown, replace them all, don't trust capacheck	JYN
LG	RP14CB25A SC 023A	Does not turn on secondary power supply oscillates	C 801 de 100uf x 35v		elet sto anonio rf
LG	32LB580B	Turns on the blacklight without image but tsound is sound.	SMD capacitor shorted on the screen drive board, c151 I just removed it and it worked, and half of the LEDs were burnt out of the 18 it has, I just had to change it and proto.		Galileu Rocha
LG	CM4340	Turns on without sound then presents 5 protection	Optoacoplador pc 903	Replace it and everything is fine	Eletronicazetec
LG	50PA4500	TV turns on, the logo appears and the screen goes off, the sound remains	Capacitor c 256 of 22mf exhausted on y sus and I just changed it and the TV worked normally		robhwood
LG	32LD420 32LD460/42LD4200/42LD460	No video, dark screen with bands in the background	Missing 12v on c619	Replace mosfet q409, measuring on the board it does not give a short	Thiago MC Eletronica Jaú
LG	55UH6500	Does not turn on, power supply board defect. power supply oscillates the normal primary, doubles the 400v but tsound is no 13v in the secondary.	Open 1Ω smd resistor r110, which feeds the power supply primary transformer winding.	Replace the resistor with one of the same value.	rafaelmoraes99
LG	42LN5400	Turning on and off	Cold welding at the power supply	Resolder suspected components and clean the board with isopropyl solution and thinner, dry well.	DSSTECH
LG	42 PG 20 R MA AM ZYLBZ	The sound increases by itself, tsound is no point in changing the keys. green LED flashes intermittently.	Two smd transistors that are on the infra red board, replace the two npns, q101 and q 102.		paulo cezar esteves
LG	RP29FA30A	No luminance, dark image, if you enlarge the screen the image appears right in the background	As per the tip, replace q509 c3198	In the case of this TV, the transistor was shorted	Mitzko Eletronica
TV LG	32LK610	Remote control sensor inoperative	Va4002 shorted killing the 5v on the control sensor board	Remove the same	Erick som
LG	55LD650	HDMI doesn't work, turning off by itself, sometimes it doesn't turn on	Processor bga solder	Reballing	GABSENS
LG	42LD420	Turns on and off (the lamps blink when the TV turns on)	Ic 301 que faz o back light ( bd927df )	Replaced the ic 301. the problem was solved.	DANGRA ELETRÔNICA - SÃO PAULO
LG	29CC9RL CW-62C	No sound and screen closing on the sides	Changing capacitors c 314, c 808 and c838	Resolved	TAVARES
LG	LM-U1350A	Very low sound replace strx6759 you can put strx6757 as long as it is original and with 4 terminals forward it is great	Strx6759 ou strx6757		robert
LG	LGD625	Does not turn on, secondary power supplys zero! without any intention! apparently normal primary, check the zd902 10v diode	In my case zd902 10v		DIM ELETRÔNICA
LG	55SM8600PSA	Doesn't connect at all.	Ic1700 burnt out.	Replace ic1700, it is the same as ic2100, smd 3208 regulator.	ZENER Serviço Técnico
LG	32LE5300	Does not tune channels, or tunes disappear after a while.	Defective main board, in the tuning circuit.	Smd ceramic capacitor c3006 shorted, interrupting power supply to the tuning block.	RNSPTEC
LG	32LK510BPLD	It gives no signal.	Shorted smd capacitor c5612, replace and run for the hug!	Replace c5612	NCTIC REPAIR
