Make	Model	Symptom	Problem	Solution	By
LG	RP 20CC25	Nothing works, just power supply to the primary power supply capacitor	Leak at the horizontal output plus cold soldering on the computer and memory	When checking the primary power supply I realized that there was no faulty component but the TV did not generate or have power on the second or +b I checked the horizontal output and it was very hot when removed it had a very high leakage and I replaced the LED on the stand bay It turned on but the TV didn't generate so I resoldered the computer and the memory and everything was ok.	moroni eletronica

MONITOR LG	T730SHK-FLATRON T17PC-0 *	When the monitor arrived in my hand, the defect was that it only turned on when it got hot, then it started to turn on only in the afternoon and then it remained alone and then turned off, I found that the c-954 was without capacitance.	He changed it but I put the capacitor at a higher voltage and everything went back to normal.		wagner
LG	21FS4RLG	Turning off after a few minutes of operation.	R420(220k) linked to the emitter of the q403.	(+b protection circuit)	Manoel (Noca)
LG	29FU6TL	Burning the 2sc6090 (horizontal output)	18k polyester capacitor replace even though it measures good	I tested the 18k cap in the test and it measured well, I even burned two transistors, but after I replaced the capacitor it worked normally	Bruno nicácio This email address is being protected from spambots.

LG	LM-U1060A	With low audio	Ci strx6759	Ci strx6759	ELETRONICA AZEVEDO
LG	47LB7DF	It takes a while to turn on, the LED just keeps blinking	C from power supply c202,217,210,221,200		Bruske
LG	RP-14CB25A MC-059A	Vertical closed	Capacitor c314 (ceramic)	Replace of the same	Edilson Bomtempo
LG	RP29CC26	Normal power supplys, turns on, has audio and filament, but there is no luminance on the screen, when opening the screen you notice the screen slightly lit and distorted.	Ic301 (tda4863) vertical output short circuit, it can be a difficult ic to find the tda4865 satisfactorily replaces the tda4863.		WAGGUINHO
LG	29FS4RL CW-62A	Screen with image from the middle up and shaking	Vertical oscillator pulse with fluctuation	Polyester capacitors on pins 76 and 77, c561 and c562, there is no point in measuring, putting the charge to replace ci tda 4863aj	JOSE FERNANDO (SO CONSERTOS ELETRÔNICA)
LG	21FU1RL CW81A	N league led access	R806 39k open it is located at the power supply connected to the regulator pin strw6554a ic810 remember that in the scheme I downloaded it was another 8817 client regulator	Changing the r806 39k everything came back ok this TV is close to the beach so it was very seay, help yourself, hugs everyone, my professional friend	marcos melo cascavel ceara
LG	21FX5RL	Horizontal weapon but then activates protection, neither image nor audio appears	Flayback winding shorting out	Flyback replacement	oltecti
TV LG	29 FU6TL	Tv lg 29fu6tl no image appears sound is normal lights up the filament has high voltage but no image appears	Loosen the screen wire and measure the screen voltage by adjusting the screen potentiometer minutely, it should vary around 450v +or-. If the voltage varies, the flay will be fine, if it doesn't vary, the flay will have to be replaced. check the screen's polyester capacitor that goes on the tube plate. Another test to be done to see if the tube has a shorted filament: loosen the tube socket pin (the socket pin where the screen wire goes).	Turn on the TV and use a screwdriver to tap the socket pin against the track where the screen wire goes, do this several times suddenly until the image comes out. It's already happened to me here where I just loosen the pin from the socket where the screen wire goes and turn on the TV and the image opens and then I just solder the pin again and go for the hug.

MONITOR LCD LG	LG FLATRON WIDE LG M228 WA	Completely white screen	Fusivel na canvas plate		Assistec Caeté
MONITOR LG FLATRON	EZ-730	Flatron ez-730 - image with intermittent aliasing	Occasionally the image was distorted only in the contours and persistence or shadow in the image, like a ghost and all of this manifesting itself once a day, when it did.	I came up with the idea of replacing 3 ceramic capacitors close to the fly-back, without success initially, but when replacing the c406 the defect never returned.	bf.colatino
LG	21FJ6RB-LD MC-059A	It trips immediately after being turned on, with high voltage at the 110vdc power supply.	Leaky transistor q804(ka341)	Replace the same	jheliocavalcanti
LG	CP-20B85	No contrast	C514 of 223 / 200v shorted r547 of 120k and the d502 confuses	Replace	ELETROCLAUDIO AGUAS BELAS
