The 24v power supply burns out, after being repaired by the sector, it worked with a hissing sound on the t801. | It was the r859 0r47/2w. 0r47 2w "wire" resistor must be installed. the squeaking disappeared. the original is made of wire, but it burned. | Giovani Pires Bitencourt | |

No image, backlight on and screen slightly bluish due to the brightness of the LEDs. | Def. on one side | Follow the tips on the forum, disconnect one of the flat cables from the t-con, (attention you will need to make a continuity jammer from the r354 to the other side, the r351 in the r354 leaves 12v and enters the r351, you have to pass through it if it doesn't burn at t -con , after the repair, keep the jamper and. | valdir ,Macajuba-Ba |

TV turns on then turns off and the relay keeps hitting and doesn't turn on again and the primary power supply capacitor gets charged | The cause of the defect was the 220k resistor r633 which was damaged, just change it and the TV will work again | Replace the 220k r633 | AssisTec - Manari-PE |

Orange LED flashes, turns off after a while, unstable voltage across the main board connector. | It was noticed that some tracks were broken from the power supply close to the main board connector, capacitors cm859 and cm856 were defective. | All the tracks close to the power supply connector for the main bridge were redone, all the voltages were correct again but tsound was still no signal, I went to the tcon board, as the main board turned on normally, so I removed the cable from the tcon board and the black light turned on. So I removed one of the cables from the tcon board and half of the image turned on, so I cleaned the tcon board connectors and it later worked. If it doesn't work, try checking the tcon board like I did. | Charles Silva |
