Lg Repair Guide: Common Issues and Fixes
Brand | Model | Fault | Detailed Problem | Solution | By |
---|---|---|---|---|---|
LG | FFH-V386 | No audio | 12v missing in voltage regulator ic705, q311 (2sa1273) short | Replace q311 | Matias ERP |
LG | M275WV | After some time on, the sound disappears | 2 capacitors | I replaced 2 47/16v capacitors c712 and c713 I put 47/25v | XANDARE |
LG | 32LK330 | Does not tune in to any channel. | Ic 1703 | RBeletrônica | |
LG | 43UK6510PSF | No image | Shorted capacitor on the vcon board! In my case, I measured practically all of them but the defect was on the left plate! c1105 shorted! reminding everyone that it is not a rule. Tsound will be cases wsound the display itself will be shorted! abs | Rafael Sena | |
LG | 49LB5500 | In standby, press power, it appears that the board is working but it does not generate 12v for the tcon nor does it obey commands | Fet q406 just above the leaky flash | Ariel Santos | |
