|---|---|---|---|---|---|
| LG | 43LJ5550 | Standby light comes on when you press the power button on the control stanby LED flashes 4 times | The power outputs were checked and they were at 7 volts varying | The power supply board was replaced as it could not find a ci smd sc2016 position u601. | Adriano Miranda |
| SEMP | LC3246WDA | The image appears and turns off with a loud noise from the speaker, then turns on again | Eprom memory in position n 503 | The replace of the same | Airton Filgueira |
| PHILCO | 2130 | Vertical closed | R 708 e d 702 perto do flay back. | Tec. zidane | |
| PHILIPS | 32PHG410978 | League has sound but no image | After checking everything and thinking it could be the negative led bars | The problem was with the output of the black lights socket, it was the IC that triggers the LEDs in shorts, it is close to the connector and it is the only one with 3 large legs on the power supply board and just replace it and go to dim dim | ELETRONICA PUBLISOM DE NATAL RGN |
| AMPLIMATIC | ET500 SLIM | Turns it on and the image disappears | Rv1 | Replacement | eletronica do gilvan |
| SAMSUNG | PL43F4900 | It doesn't turn on, when it turns on, voltages vs and va appear and it goes into protection. | After separately checking the power supply without the main board, using a 100r resistor from the ps_on pin to ground and 3k3 of the stdby voltage (5.2v) to the so vs_on pin, all voltages appeared normal. Even without the main board, I tested it by connecting the y and zsus boards, the vs and va voltages remained unstable, all that was left to do was check the main board, I turned off the bluetooth module and the TV turned on without showing any irregularities. | Replace the wibt40a bluetooth module. | edumiguez |
| CCE | LN39G | Turns on normally, after a few minutes, the image disappears at the top of the screen. Give the TV a small tap on the right side edge and everything goes back to normal for a short period of time. | In my case, I dismantled the screen and saw 3 contact strips, on the right side of the screen. the middle tape was the cause of the problem, caused by the screw that holds the frame. Tsound's no point in just removing the screw. | You have to find a way to immobilize the tape in a certain position and fix it. or, replace the screen. | arock |
