Standby flashes 3x and does not turn on. | Short power supply. | Burned out smd components making reference impossible. with scrap board follow the references: ds821 smd(a4w39), smd rs809(103)10k, smd rs806(200)20r and on the top mosfet qs801c, qs802c (both mdf9n50). Jammer required on broken trails in this case of course* | |

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 |
