LG MONITOR	L1715S-N CL43	Burned fountain	R111 very close to pin 1 of u101, wsound 300v is present; enabling the arc.	Substituir: u101(fan7601); r111 (0r56/2w); q101 (7n60b);f101 (3.15a/250v);r102 (1k-smd); d103 (1n4148-smd). isolar e afastar a r111 do ic.	jose luis calcada
LG	CP29Q50	It only turns on with sound and turns off after 5 seconds.	Cold solder 120v pin on p11b.		bobra
LG	CP29Q50	Image goes up and disappears	Cold solder on q405.		bobra
LG	29FX5CL CW62A	Dark stripe on the left side and excessive width	R412 (7k5) open		ARAUJO
LG	29C85	It turns on normally and suddenly for 2 seconds it forms horizontal stripes and multiple images, and turns off, all very quickly.	With a magnifying glass I looked at the horizontal and vertical circuit, looking for anything with cold soldering or broken tracks, then I found a fault in the connection strip for the vertical circuit, fixing the fault it worked without any problems.	My tip is to always pay attention to the image or signs that indicate and help identify the sector wsound the defect may be	Emilio C.A.A
LG	CP29K30A	It doesn't turn on, nor does the standby LED, and the T802 power supply transformer (6174vmcb01r) keeps clicking like the ticking of a clock.	The problem was the horizontal output transistor was shorted, this caused it to not turn on even in stand-by and the power supply kept clicking like a clock ticking, because it tried to turn on the power supply and it shut down.	I solved the problem by replacing the horizontal output transistor q401 in the case of my TV it was 2310ht but in the schematic it was like d2581.	ronsoares
LG	TODAS TVS 21 E 29	No image	Tube with shorted screen	Measure and see if the screen voltage is at 0v, if so, remove the screen wire from the tube PCI with the TV turned on, and increase the screen on the fly back to the maximum and then give several touches with the screen wire at the point wsound it was removed, I have solved many cases like this	MANINHO
LG	700S -CB777G-NE	Nothing happens (has normal supply voltages)	C954 disabled	Replace the same with another (1000μF 10v)	cardosojp
LG	42PC1RV LG	It turned on and off by itself, the menu appeared and disappeared	TV control board corroded by humidity, strange as the other boards are in perfect condition. I think it was a lack of protection of the board by the manufacturer (I have a photo)		Luiz

LG	RP 21FB 32	Turns on and off after a few minutes	Change the (75k) resistor that goes in the abl for one (100k) and can deliver it to your customer		rhaus
LG	STUDIOWORKS700E	Lack of synchronism, horizontal lists	Resoldering the transistors in the power supply region		Cleber
LG	LAC-M8410R AUTO-RADIO	Does not turn on, when connected to 12v the CD eject motor activates for a few seconds (normal)	Leaky transistor q260 (2sc3205)		slh_electronica
LG	CP-29K30	Flashing (disarming)	Note that the ci vertical output heats up, change it, then go to the horizontal stage, tsound are 2 large diodes, one must be shorted, pay attention (high frequency) change it and go for the hug, good luck jose vicente		jose vicente
LG	PT 20A35	LED blinks blinks and does not turn on	Flay back	Substituted	BASK
