LG Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| LG | 42LV3400 | Does not come out of standby | I replaced the ci l6599d, however, the TV still didn't turn on. After researching, I realized that the l407 coil (on the main board next to the connector) had glue on top, disturbing the contact. After warming up the point, the TV worked normally. | NiloTech | |
| LG | CM9530 | Connect 5v giving 4.5v pin 1 ic700 check r7b2 under the board. | R7b2 was changed giving 49k | Replace the 5v and it's normal. | Eronaldo (erontec) |
| LG | 21FJ8RL CW81B | Vertical closed | R311 30k | In my case I just replaced it and it resolved | SAM VIDEO SOM |
| LG | 42LB5800 | The screen's LED bus, stand bay, did not turn on, it blinked once 3 times, one quickly and 2 long. | An external voltage was injected onto the LED bus to see if tsound was anything burnt and everything was ok, at the output of the board voltages that feed the LEDs were present, the problem was in the connector that connects the lamps to the board, the cable was soldered directly on the board, it worked normally | Rodrigo Coelho | |
| LG | 50PT350B | Doesn't start | Short z sus board, replace shorted 30f124 transistors, in my case tsound were 2, it worked 100% just replace | reginaldo moronte,eletronica junior caldas novas | |
| LG | 21 POLEGADA ESTA SEM ETIQUETA | TV working normally when you turn on the DVD image shaking as if it were the video cable | 4k7 resistor 512 measuring 5k | Replace r512 | francisco |
| LG | 32LE4600 | TV with sound but no image, blacklight on | Its t-con board is on the main board itself, tsound was an integrated one getting too hot and I noticed a shorted smd 659 capacitor, I just removed it and the image came back. | Galileu Rocha | |
| LG | 42LD840 | With image, and sound, but image in slow motion and sound also in slow motion. | Crystal 54,000 (x903) next to micro ic100 | Replace of the same. | arock |
| LG | 42LS3400 | Break light on without image | T-com, c210 shorted. | MARIANO TV TÉCNICA BARCELONA | |
| LG | PJ350 | Does not turn on by hitting the relay | Photo coupler pc 901 and pc 902 replace | edinho eletronica matos | |
| LG | 26LG30R | Does not turn on, stand by LED is off | 12v voltage varying, removing the connector that goes to the main, voltage stops varying..short in the main | Cc1104 shorted. | Maurilio |
| LG | LC42T17, 32LG30R | It takes 10 to 15 minutes to work. the power supply has voltages +5, +12 and +24 | Check scaler board capacitors | Edson | |
| LG | LN40R81B, 32LG30R, LC42T17 | Scratches on the vertical and dark screen with normal sound. | Reballing on faulty t-con or ci | Edson | |
| LG | 20CD2R | Burning the horizontal output after about 15 minutes reduces the panel on the sides and the transistor shorts out. Note: normal power supply with 110 volts | Altered t 403 horizontal driver transformer | When replacing the TV it works perfectly. | REAL ELETRON CARVALHOS MG |
| LG | 42LD460B | Blinking but not turning on | Q710 shorted and f501 open on the power supply board | I put 2sk3667 in place and it worked | Marcelo |
| LG | CM5660 | Turns on everything works but tsound is no sound | Transistor q106 next l102 open. | Measure if tsound are 12 volts that power the ci tas5631, if the opu is missing, check if the 12 from the power supply is normal, if confirmed, check q106 which switches the 12v to the ci audio output | CONSOVI |
| LG | 32LE5300 | When turned on it gives a beep for approximately 3 seconds and then tsound is no image or sound signal | At power supply, pfc around 390 v. ok and standby voltage 3.5v. ok, but it doesn't have 12 and 24v voltages. | Ci smd l6599 defective, I replaced it and it solved the problem. | PATRICK ELETRÔNICA |
| LG | 32LV5300 | When turned on it gives a beep for approximately 3 seconds and then tsound is no image or sound signal | At power supply, pfc around 390 v. ok and standby voltage 3.5v. ok, but it doesn't have 12 and 24v voltages. | Ci smd l6599 defective, I replaced it and it solved the problem. | PATRICK ELETRÔNICA |
| LG | 20CC25 | Vertical folded on top | I changed capacitors and resistors around and nothing solved it, so by intuition I changed the memory and the defect was corrected. | Eliel Magno | |
| LG | 32LK330 | Completely inoperative, tsound was no 3.5v stand by voltage | R 519 open | Replace 1m resistor | Eletrônica JJ |
