TV does not turn on, has normal ST BY, when activating power, the voltages appear normal on the main board for a few moments and then disappear, leaving just 5V ST BY, VS and VA voltages do not appear at any time, even when turned off the y,z sus plates. | Defective power supply board. | Replace ic801 -ncp1397bg, failure in this component causing the board to become unusable, check q601 and q602 together. | RNSPTEC |

It turns on normally, after it warmed up it stopped ringing and did not respond to commands, when it was unplugged it would not turn on again. | Crystal x500, to test I heated it with the station and the radio didn't turn on, then I cooled it with isopropyl alcohol and the sound worked normally. | Replacing the x500 crystal with a 24mhz one like my friend has many cell phone cards. | J&M |

Flashing the backlight | The supply voltages for the main PCI were normal. Even arming the power supply separately from the main one, the backlight continued to blink, making it likely a defect in the power supply PCI, the backlight was already discarded as it had already been replaced. | Defect in the inverter part of the power supply; We managed to solve it by making the following replaces: remove the following components: q805 and q802 (by removing these two transistors the TV will stop flashing the backlight). Now to reduce the power supply to the LEDs, it is necessary to remove resistors r836, r835, r817 and r818. | EC |
