| LG | HT 503SH | Turns off by itself in seconds | I noticed that the DVD mechanics wouldn't open | Reflow in the processor when the mechanics are low | Fer |
| LG | 32LS3400 | As x doesn't connect, | If you turn off the keyboard and it's fine, it's because the keyboard is conducting. | Disconnect orange and red wires from the keyboard. This eliminates the keyboard. working only by remote control | oskarala |
| LG | 32LS3400 | Does not turn on nor does the stnd by LED light up | R 506 changed from 750k to 50k | Replace the same | jcgiantomaso |
| LG | CM4520 | No sound comes out of the speakers, the cooler keeps oscillating and after about 2 minutes +or- it turns off | Tsound is no pvdd voltage, when turned on it reaches 30v and then drops. | PC903 photocoupler oxidized and broke. | Lucas |
| LG | 32LS3500 | It only has the +b 3.5v, but the 12v and 24v ones are inoperative. | It appears to be a defect in the power supply's ci l6599ad, but 24v line with short in c smd next ci audio amp | More repair tips on YouTube channel direct to the defect | BRUSKE |
| LG | 49UJ5654 | TV flashes stand by but doesn't turn on | Capacitor s.d. shorted on the wifi card. (no cap position information) | Replace the capacitor or replace the board. | Washington ELETROWASH SOLUÇÕES |
| LG | 14SB1RB | TV turns on with normal video, when inserting video signal via RCA, synchronization is lost | Changed resistor r512. | Changing the resistor and resoldering the board. | Washington ELETROWASH SOLUÇÕES |
| LG | 32LK615B LA84J | Doesn't start. no signal. | Replacing the main board. I lowered the inverter current to avoid return. | Added a 0r68 resistor to r816. the measurements were 25.4v and 662ma, with back light at 100%, for 24v and 427ma. | Eletrônica R-Tec |
| LG | 42PJ250 PJ | Blurred image | Coil l1 zsus cold welding | Solder l1 zsus | Adao o gatao |
| LG | 40LF6350 | League without image | LEDs burnt out, the LEDis were repaired, but you have to change the whole kit | Replace the LEDs and reduce the voltage by changing the 3r2 resistor r816 for 8rde 2w, the voltage from 197v dropped to 181v. | ELETRONICA JUNIOR BELEM |
| LG | 50PB650B | With sound and without image | When carrying out the necessary checks, I noticed the lack of 18v voltage on the zsus board. | When inspecting the ysus board, we noticed that the 18v voltage comes from this board, next to the two photo aclopad you will find the capacitor c204 (150μF/35v), being shorted it causes this defect when changing the TV it returned to normal. | Rivaldo Lira |
| LG | 42LB9RTA | Does not turn on or takes a long time to turn on | R615 smd code. (8253) 825k, with glue underneath leading. | Remove clean residue from under the resistor | Hndrsn |
| LG | 47LB5800 | It turns on and off, sometimes the standbay flashes, other times it turns on and stays on for two or three days without showing the defect. | SMS resistor 126 on the power supply board, 100k changed | Naldo Lima | |
| LG | 47LD460 | With image and without sound | O ic 2901 . ???? | JF.eletro | |
| LG | 14FFK3 L2 | No color. I changed the computer, re-recorded the EEPROM, and the defect continued. | X501 , 4,43361mhz | GDP2 | |
| LG | 47SL90QD | It doesn't work, just the standby LED blinks. good power supply. | Shorted and charred smd capacitors on black light pci | Replace c302 | Danubio |
| LG | 29LN300B | The LEDs do not light up, the screen is off and Q1002 has a short circuit after changing the Q1002, it burns out again | Replace q1002 and in the path between it and ic1001 tsound is an open fusitor on pin 21 | Resistronic resende | |
| LG | 60LA6200 | Does not turn on, stand by LED blinks | Coil l2400 open is c2402 shorted | Replace. | Maurilio |
| LG | 47LM6700 | TV does not turn on red LED dialing and did not turn on, 12v and 24v do not appear | Changing the q2401 on the main board near the power supply connector | Resistronic resende | |
| LG | 29LN300B | TV turns on, the image appears and then the screen goes off, with the LEDs and screen good | Broken track on pfc circuit | Carlos |
