LG Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| LG | 21FJ8RL | Horizontally turned, i.e. image lying down (like bars) | Altered 22k 512 resistor | Replace r 512 | ON-PLAY ELETRONICA |
| LG | RP-20CB20A | Very low and hoarse sound you can only hear at maximum volume as if it were memory | Resistor (r625) de 22k | Replace for the same value | Eletrônica Bastos |
| LG | 32LV3700 | TV turns on normally, red LED turns blue, but no image and no sound | In my case it was cold soldering on the BGA (processor) on the main board | I took the plate to the oven at 200ºC for 10 minutes, preheated for 1 minute beforehand, let the plate cool, assembled it, put a cooler on it and the TV has been working normally for over 1 month, the TV is mine, not a customer's. | Ricardo Montes |
| LG | RP14CB20A | Image without horizontal synchronism, the image is colored in the form of sea air in the av and rf | Defect near ic501, changed resistor 4k7 just change the image normalized both av and rf | Resolved | Carlos |
| LG | RP14CB20A | Image without horizontal synchronization, both and the shower effect | Close to the ic501 - lg631 9r, to a resistor position r512 - 4k7 1/8w miniature it is leaking, I measured in the digital test that the 4k7 is giving 5k1 it is changed, I changed it resolved the image was normalized it was ok in both the av and rf | Defect resolved | andre |
| LG | 29FE8RL | Turns off after a few minutes. | Replace resistor r843 220k | Replace resistor r843 220k | DJ PITUKA |
| LG | 42PJ350 | Has audio and no image | Check buffer board or oxidized t-501 | Resolved | JORGE ASSISTENCIA TECNICA |
| LG | CM4320 | Turns on without sound and without the red LEDs on the edge of the volume turned off and then turns off | Q-953 with leak | The replace of que-953 for bd135. | naldo oliveira |
| LG | LT27B350LBMZD | Doesn't start. standby LED flashes twice in a loop. | Schottky diode sr5100, position dm851. As it works in parallel with the dm852, I decided to replace both. Once this was done, the TV started working normally again. Hugs to everyone and don't forget to send your repair tips, it helps a lot!!! | AnisioH | |
| LG | 26L30R | Lamps don't turn on | F 1 an ap looks like a resistor has the number 20 on it note it is on the iverte plate | SALES ELERONICA | |
| LG | 32SL5700 | It doesn't turn on, it doesn't even light up | Testing the power supply secondary diodes (d251 to d254), they all had a short, when removing the connector that goes to the motherboard the short disappeared... in other words, a short on the motherboard.. | C5422 short (close to the audio output ci) | Maurilio |
| LG | 22MA33D-PS | Inoperative TV won't turn on, plus normal 19v power supply | Capacitor c803 shorted, causing ci 809 to burn, it is close to the flet that goes to the display. | Ci 809 and mp158 must have 24v at the output, the capacitor c803 can put 4m7 63v smd | guinga sdia goias |
| LG | 47LM6210 6200 6230 | It does not tune digitally, but analogue tunes normally. | Voltage +1.23v_d_demod (low voltage, 0.50v) that goes to the tuner pin 30. this voltage is provided by the ic6501 ap2132mp-2.5trg1. This ic is close to the tuner | Replace ic6501 and it worked, it worked perfectly and the voltage 1.23 appeared normal. | MIGUELTV |
| LG | LV3700 | TV doesn't turn on, LEDs don't light up, standby lights up dimly. damaged main board | Reflow the processor and nand memory. put a good amount of liquid flux underneath. | Rmseletronica | |
| LG | 32LH515B EAX67026901 LJ67A | TV completely inoperative | Ic500 mp3378 burned | After the replacement, the TV started working perfectly again, remembering that the component code is mp3378, because if you search for the code above you won't find this component anywsound, it is already for sale on the open market | marco antonio |
| LG | 32LB9RTA | No audio, no sound | Hdmi ci shorting the 3.4v | 3.4v low, around 1.0v, beeping the capacitor tsound was a short, disconnecting the power supply board from the main board the short disappeared, we found 2 smd capacitors with a short on the back of the board, close to the plug that connects to the power supply , we put a voltage of 5v on them and the hdmi ci heated up, we removed the ci and the audio came out perfect. partial solution = remove the ci, however you will be without the hdmi function. total solution = replace the hdmi ci. | EC |
| LG | 29FX5R | R405 heating up, ticking and not turning on | Ic824, regulador 5volts | sandro | |
| LG | 50PJ250 / 350 | Screen stains and drizzle | R426 (2r2) y-sus plate and cold weld no fusivel fs1 na z-sus plate | Tsoundfore a brigade | OZATEC ELETRONICA SARANDI/PR |
| LG | 42LF20FR | It doesn't turn on, it doesn't even light up | Tested the power supply on bench everything ok.. | C1019 on the motherboard shorted (near the connector that comes from the power supply), this shorted capacitor kills the 5 volts that come from the power supply. | Maurilio |
| LG | RP14CB25A MC-059A | When plugging the TV into the socket, the standby bye LED flashes directly and the power supply's large capacitor remains charged as if it were the str | Z851 6.2v | ELETRÔNICA MUNIZ |
