It doesn't turn on, when it turns on, voltages vs and va appear and it goes into protection. | After separately checking the power supply without the main board, using a 100r resistor from the ps_on pin to ground and 3k3 of the stdby voltage (5.2v) to the so vs_on pin, all voltages appeared normal. Even without the main board, I tested it by connecting the y and zsus boards, the vs and va voltages remained unstable, all that was left to do was check the main board, I turned off the bluetooth module and the TV turned on without showing any irregularities. | Replace the wibt40a bluetooth module. | edumiguez |

Turns on normally, after a few minutes, the image disappears at the top of the screen. Give the TV a small tap on the right side edge and everything goes back to normal for a short period of time. | In my case, I dismantled the screen and saw 3 contact strips, on the right side of the screen. the middle tape was the cause of the problem, caused by the screw that holds the frame. Tsound's no point in just removing the screw. | You have to find a way to immobilize the tape in a certain position and fix it. or, replace the screen. | arock |
