| LG | RP20CC25 | Contrast does not work | Diode (d501) in4148 shorted | Replace | Bruno nicácio This email address is being protected from spambots. You need JavaScript enabled to view it. |
| 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 tsound 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, tsound 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 wsound the screen wire goes). | Turn on the TV and use a screwdriver to tap the socket pin against the track wsound the screen wire goes, do this several times suddenly until the image comes out. It's already happened to me sound wsound I just loosen the pin from the socket wsound 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. | MAURÍCIO |
| 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 |
