|---|---|---|---|---|---|
| LG | 50PN4500 | Turns on, a very weak, drizzled image appears and the screen remains blank with only sound | D401 near 150uf x 250v capacitors | Sylvox | |
| LG | 32LM627BPSB | Doesn't start | Power supply ok. main voltages ok, shorted capacitor on the wifi module, disconnect wifi cable, if it works shorted capacitor defect | fabiusmax | |
| LG | 32LH35FD | It turns on normally but when you put the antenna in and the image appears, it locks and only comes back on if you unplug it. | Capacitor smd c829 330uf 16v | I put in a 470μF 16v electrolytic, just run for the hug. credits to the cate channel electronic technical support center. https://www.youtube.com/watch?v=htllqjbanbi | RYK |
| LG | 49LF5400 SA.BWZYLJZ | The TV keeps blinking the stand-by LED and the backlight blinks at the same rate. From what I saw, one side shows that the backlight lights up when the backlight blinks and the other side doesn't seem to turn on when it blinks. | Credits to gl technical assistance, through the youtube link: https://www.youtube.com/watch?v=kxbjc4-znom | It explains very well that the fault is in the backlight and even shows that a ruler is leading to the TV ground, close to 20Ω and in my case it was that too, so diagnostics of the bus short circuit with the GND housing. | MIGUELTV |
| LG | 42PX4RV-MC RF-052C | Bad image, blurring only on the HDMI input. | Check resistors from 22r position ar1200 to ar1205 above the hdmi circuit. measure all 22r lines individually, in my case I had only opened one line of the resistors. | rafaelmoraes99 | |
| LG | 55LA9650 | Doesn't start. power supply shorted. | Shorted components: ic501 ic3br4765jz, c502 47j. If, after the change, the power supply keeps the relay knocking, check the two cis l6599ad as one or both of them may have a short circuit. change components. | rafaelmoraes99 | |
| TV LG 49 | 40LJ5550 | Black screen no video | Defective screen. | Turn off the flat on the right of the t com, if the voltages vhl and vgh appear, a defect is confirmed on the screen, put a 5mm tape on the flat on the right of the t com, count 5 tracks from left to right on the flat and put duct tape insulating about 8 tracks . | Eletroberger |
