When activating the power, the LED goes from red to blue, the blue LED stays on but the green LED does not sustain it. Tsound is a lack of VA and VS voltage. power supply maintains 5v but hits the relay and disables the rest. | Power supply pcb defect, changed q951(fqpf 9n25c) changed close to the ysus output connector. in this case without defects on ysus, 08/2023. | Hugs | |

Without image, I noticed that the t-con had some points without power. | I replaced the t-con and an important tip, as it is very difficult to get the same on the market, I took a risk and bought the t-con for the Philco PTV50M60SS CV500U1 TV, despite some different components, it worked perfectly well. | ALBERI F S | |

TV doesn't turn on, just the backlight keeps flashing with the relay beating. | Check two cis responsible for the backlight on the power supply PCI. see slc1013m and slc2013m. If the backlight flashes at the top and bottom, it means that the center LEDs are not lighting up and the possible defect is in the SLC1013m and if it only flashes in the center of the screen, and does not light up at the top and bottom, tsound is a possible defect in the SLC2013m. | Replace of cis slc1013m and/or slc2013m | rafaelmoraes99 |
