Make	Model	Symptom	Problem	Solution	By
LG	21FJ6RB	Black bar at the bottom + or- three fingers	R-305 amended	Replace it for another like it	ELETRÔNICA CAVALCANTE
LG	21FJ6RB	When plugging it into the socket, the LED was on but it didn't turn on either with the control or the keyboard	C-11 - c12 and the crystal both next to the micro	Replace it for another like it	ELETRÔNICA CAVALCANTE
LG	29K30 MC-022	TV turned on with retraction lines and turned off I found the capacitor on the 220v line swollen in the rear, it's the others on the line didn't solve it	Tda6107jf	Tda6107jf	ELETRÔNICA MUNIZ
LG	26LG30R	Turns on, with audio, screen lit brightly and without characters. changes channels but no image.	Tcom without power supply.	Replace double mosfet si4925bdy behind the tcom jack.	BICHARA
LG	LG26LG30R	Does not turn on, red LED flashes blue twice	Supply missing 12volts and 24 volts low	Replace transistor stn 2222 (replacement bc 639. invert the cbe and ebc terminals)	BICHARA
LG	CM4330 EAX64991501	Sometimes it turns on, sometimes it doesn't.	6v2 zener diode, position zd902 and 6.8nano polyester capacitor position c908, changed.	Swap 6v2 for 8v2/1w and 6.8nano for 10n/50v and that's it...	LUCIANO ALQUEJA
LG	42LG50D	Doesn't start	Fet q601 with leak, fb601 open, tv already turned on, but pfc wouldn't bend, ci u601 defective.	Replace these parts and the TV was ok	Maurilio
LG	21FU4RL	Power supply low TV does not oscillate secondary 85v	R844 of 4k7 measuring 6k2	Replace 844 4k7	JUNIOR
LG	MCT704	So no standby (relogio), sem audio	It only arrived on standby, it was a CD2 touch key, then it turned on normally but tsound was no audio	I tried everything to solve the audio problem but without success, tsound was no =65v or -65v for sound output, the only solution was to place a 33k resistor between pins 3 and 4 of the pc901 photocoupler and another on the pc902, the voltages returned +65v and -65v and sound working normally, it was the only way...	Gleyton
LG	42PJ350 PD01A	It turns on and then goes back to standby and doesn't turn on again until you unplug it.	It was verified that q605 did not release 12v for the doubler and the ic l6599. photo 103, responsible for switching this transistor, was changed.		joaomvjr
LG	29FU6TL	Change channels, adjust the volume, but with the screen completely dark. normal scrim voltage. Acting on the screw potentiometer quickly, a slight glow appears and goes out. with the normal vertical (open).	Vertical ci defective ic301 (stv9326 ) and open fr401 0.05 homs.		Ademir tc
LG	CM-8350	No audio	Fotoacoplador pc902	Replace the same	riva ferrari
LG	29 FX5CL-LG	Does not turn on the off LED, it just breaks the relays	It was the 180k r830 that was open	The TV turns on but turns off immediately afterwards tsound was another resistor open, the r843,220k open, replace both	Rafael
LG	32PC5RV	Power supply relay knocking, no voltage vs and goes without 5v, it also applies when it works and keeps turning off for no apparent reason ok	R122 r123 r124 1004 or 1mg remove clean glue replace, check voltage with digital multimeter on each one, tsound should be 90v on each one as it is a divider		Luiz Técnico
LG	RP21FE85G	No image only sound	C512	I replaced and ran to another one	Antonio Carlos (Eletrônica Renascer)
LG	42LB5500	TV had sound, had black light, but dark image, main board and power supply, t-com good.	Display board with shorted capacitor, c103	Turn off one of the flets to find out which side has the problem. whichever side is bad, has half of the screen white. and just replace the 10 midro caspacitor	ELETRONICA MOISES
LG	32LD350-UA LA04A	Turns off after some time. After the first shutdown, this repeats more quickly and then never stops turning on again. keeps turning on and off.	Zd503 diode (zener 15v) leaky/altered. only detectable at x10k scale. Measure to see if possible changes in the zd504 (15v zener, very close to the zd503) and ic 502 photo coupler.	Replace and you're done.	Eletrônica R-Tec
LG	29FX5CL CW62A	Closing on the sides	Resistor r319 of 39k measuring 53k		3R
LG	42PQ30R	Sometimes the relay doesn't even turn on the LED	D352 shorted diode.
LG	RAD 136	No sound comes out	Tsound is no voltage at the output	Zener 905 uz 20sb(20volts), close to the rectifier bridge	eletronica fernandes - to
