It would turn on and within a few minutes the backlight would turn off with a dark image. | Thinking it was the bus, I opened the TV and tsound was an LED open.

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 |

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 |
