| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| LG | MS3052R | Microwave turns off when starting | Place capacitors with higher capacitance on the control board, check door locks | Place capacitors with higher capacitance on the control board | Paraiso dos Consertos |
| LG | 29FU1RL | Low power supply with 83v | Resistor r834 4k7 1/2w was faulty measuring 7k2 | Replace with a 4k7 resistor | EDIVAN ELETRONICA |
| LG | 42LN5700 | Turns on without image, however the LEDs light up | Without the 12v that feeds the tcom | Transistor q2407 open on the main board, just replace it and good luck | PATRICK ELETRÔNICA |
| LG | L1740PQ | Does not turn on - power supply varying | I changed all the electrolytics, tl431 and photocoupler, it didn't solve it, it was the ci fan7601 | You fan7601 | Pardal - X |
| LG | 29LN459M | Shorted board | Capacitor c718 smd | Eletrônica Cecé. Brumadinho MG | |
| LG | 32LB620B | When plugging the TV into the socket, the standby LED would come on and go out immediately, the power supply had all voltages and the TV would not turn on. | MOSFET transistor Q405 on the main board, in parallel with the capacitor C427 measuring 12V on both terminals. Replaced the MOSFET transistor and the TV started working again. | Substituir transistor mosfet q405. | Manoel Damião |
| LG | 14FK3RB MC059D | Does not turn on or light up when in bay | The cause was u photo coupler and dz801 closed | Replace both the dz801 and the photo coupler | Silvan dos santos |
| LG | TV 32PC5RV PS7231/1 | Standby LED lights up green, takes 10 seconds and returns to red | Replace transistor q951 emcurto 9n25c e c904 replace | Shorted transistor and replace the c without testing | Simiao machado |
| LG | 24MN33D-PS | TV didn't even turn on or stand-by | In my case smd capacitor on pci shorted | Replace the capacitor in position c804 | Airton Filgueira |
| LG | RP21FE85G | Turns on the relay and turns off, goes to protection | Open resistor fr403 that goes to +b of the flyback | aquiles | |
| LG | 32LD420 | Dark screen, normal sound | Voltage on capacitor c659 low, normal is 8v | Leaky capacitor c619, l604 and q409 burnt below the board. When replacing components, the IC600's voltages returned to normal. If you don't have the q409 to replace, make a jumper between the drain and power supply. | Eletrônica JJ |
