Turns off by itself, sometimes it doesn't turn on, sometimes it gets a greenish screen, it makes noise from the speaker and turns off. | It may be caused by several possible problems, carry out the following procedure to resolve and avoid a possible return. | Check the power supply and inverter board for swollen capacitors and replace them. Remove the power supply components: c108, zd111 and zd112. Also at the power supply, replace the 11k resistor r128 with a 15k or 18k one. On the main board, replace the SMD electrolytic capacitors that are close to the processor and RAM memory with values of 100μFx16v and 10μFx16v. Clean the main board well on both sides with thinner or isopropyl. resolder all fets, transformers and heatsinks on the power supply | GABSENS |

The TV turns on, but after turning it off, it no longer turns on | Just replace the common resistor r128 11kΩ on the power supply board with a 15kΩ one. | The TV constantly had this problem. When I replaced resistor r128, it resolved. | JULIANO |

Does not turn on lights and no sound, no 24 and 12 power supply. | Change c118 (220nf), it is connected next to r128, tsound are cases when the r 128 is changed and components are removed and it continues to not turn on. replace the r 128 with a 15k one, if it doesn't work increase it to 22k, remove c108- zd111 and z112 and replace c 207 and 208, both 3300/10v. | joaomvjr | |

Doesn't start. TV turns on and after turning it off using the remote control, it no longer turns on. | Probable cause; c108, zd111 and zd112 ( smd) power supply. | In the protection circuit you will find components c108, zd111 and zd112, they must be removed from the circuit! put; portaldaeletronica forumeiros.com | Fórum Portal da Eletronica |

It turns on normally, but then the sound disappears or turns off. | The components were removed from the power supply and the r128 was changed from 10 to 22k, but it continued so I decided to resolder the IC801 on the logic board, I resoldered it with an iron and solder, with the air station it didn't look good, new solder has to be melted. Resolder the other ICs too. | joaomvjr | |
