It turns on, but tsound is no sound and it works partially, with the mixer setting in the middle, it keeps hitting the speaker, in fact the operation is incomplete, some LEDs for functions "a and b", type usb "a"/aux/tuner/etc , do not light | All normal power supplys at the bottom, but on the main panel, the top of the device on the main board has a 47uf/10v position cap c521 that its "esr" is changed, only with an esr reader capacitance to find out, then in Doubt change this capacitor. the c521 is located next to the ic "u501 on its pin 38 | Swap c521 electrolytic 47μF/10v | MIGUELTV |

TV turned on and off | I discovered that the problem got worse when the TV got hot or turned on for a long period of time. which led to the suspicion of some component varying with heat. That was when I discovered, close to IC 1501, the capacitor in position 1024 of 10uf that changed depending on the heat applied to it. I checked the conclusion using a capacitor and a soldering iron. | The capacitor is responsible for filtering the voltage on the ic1501. I placed a common 10μFx25v capacitor and it solved the problem. | Edinei |

Normal sound screen off | This TV worked normally, but sometimes the screen was off and the sound remained normal. On the power supply board I found 3 swollen capacitors, cm812 (47μfx50v), cm859 (470μfx25v) and cb852 (1000μfx25v), they were replaced, but these were not the cause of the defect. The defect was poor contact in the flat cable socket (LVDS) that connects the signal board to the T-Con board. All I had to do was unplug it and plug it back in to return to normal. To ensure that tsound was no more problem, I applied a little machine oil to the gold contacts before reconnecting. | littlecarlos | |
