LG Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| LG | 49SJ8000 | Crashing, slowness, wifi not connecting, bluetooth failing and smart magic crashing | Wifi plate | Do resoldering with solder paste, and cleaning the adapter that connects the flet to the board, the MTU has bad contact | Maroni |
| LG | 32LB9RTA | Inoperative without standby | C506 10uf/50v | Replace the c506 primary power supply | MARCELO RODRIGO QUINELATTO |
| LG | 32LB9RTA | Does not turn on, stuck on the green and red LED | Capacitors c204 and c205 were found on the power supply board, they were replaced but did not solve the problem. | After observations and tests, I found the capacitors c1026, c1001, c1115, c1187, c1108, 470μFx16v aluminum capacitors to be defective, replacing them resolved the problem | Mitzko eletronica |
| LG | 42LM3400 | Turning off | Resolder the transistors q 400,401,402,403,405 and ic408,409 on the main board close to the power supply connector | Assistec digital castanhal Pará | |
| LG | 32LY340C | I'm sound | Remove q5600 near the sound output. Tsound will be moments when the sound will appear and then remain silent, tsound must be about 3v on the middle pin of this transistor, after it is removed or in normal operation | fabiusmax | |
| LG | 29MN33D-PS | Backlight flickering | At first you think it's a defective LED, in my case it was cold welding on the d1103 diode | Resoldar diodo d1103 | Gaera |
| LG | 50PN4500 | No image, with some pixels on the screen | Ysus card, just change it and run to receive the money | Cabeça | |
| LG | 49UJ6565 | Image shaking, reddish and with horizontal lines on the screen (and also a bluish background, LED defect) | Bluish defect, the bottom is LED, only with replacement. To solve the problem of horizontal lines and reddish image shaking, only by changing the main board, but I reduced it a lot, practically imperceptible, I put duct tape on the lines of the lvds connector on the screen, lighter blue connector, the one on the right, on the side of the main board, start by covering the lines from left to right, you can cover about 8 to 10 lines | Claudio Eckert | |
| LG | 21FJ8RL | Turns on the LED and turns it on again | Even removing the protection transistor, it didn't oscillate in my case, I just had to change c828 47 /10 v | Replace c 828 | Lincam Bezerra |
| LG | 32LF20FR | No sound. audio signal ok. | Resolder the ic600 and its peripherals or replace the ic600 and c600 c609 and c604. | samuel leite | |
| LG | 32LD350 | The TV didn't work, tsound was no signal on the TV. | Power supply did not have the 3.3v voltage to power the main board. | Next to the input rectifier bridge I found the 1mega "brown black green" r19 was open when replacing the TV and it started working normally again. | Rivaldo Lira |
| LG | RP20CC97 | TV turns on normally, but image closed from the middle down and open top with lines of retraces | R305= 12k open | Replaced and resolved | Eletrônica Renascer (Boa Vista do Gurupi-Ma) |
| LG | 42PG20R | Turns on, with sound and without image | Capacitor c515 smd on the buffer board broken, underneath it was charred | Replace c515, and remove all carbonization | HC Eletrônica Guaíba |
| LG | CP 29H90P | Vertically jagged blurred image | Image without definition | TecniTécnico Edivaldo Miranda Silva - Dangra Eletronica | |
| LG | 42LG30R ? | Turns on and within a few minutes turns off or locks the keyboard. | C 875 and c879 on the main board of 10 micro by 16 volts | Swap c875 and c879 on the main board. | This email address is being protected from spambots. You need JavaScript enabled to view it. |
| LG | MS3052RA | Restarting all the time | D103 just replace without testing!!! | ||
| LG | 32LD350 | Does not turn on, kills 3.5v | C457,c459-next to ic405-induces that c405 is leaky. | JORGE LIMA | |
| LG | 32LN570B PCB:EAX65284601(1.0) | Inoperative, not even the stanby led would light up | Shorted power supply | Blown fuse, mdf11n65b mosfet leaking position q101 leaking, capacitor in cut 331k 1kv position c102 were replaced | JEAN LORENZ |
| LG | 29FS4RL-1 CW62A | Secondary power supply with 50v. pulsing arms the relay. | Changed the r 801 back to normal | Grateful fig | Sandes |
| LG | 29FS4RL-1 CW62A | Secondary power supply with 50v. pulsing arms the relay. r 801 27 k in front of the str | Changed the r 801 back to normal | Grateful fig | sandes |
