Turns on and off immediately | Defect in the y-sus, after changing the rjp30e2 igbts. The TV turned on and all the voltages appeared but the image was grainy, you couldn't see anything. | After carrying out a new analysis, I checked 3 open resistors, 1 of 51Ω in position r5034, 1 of 100r in position r5019 and 1 of 270r in position r5025, after changing them the image came back perfect. | Luiz Sena Eletrônica HYK |

When plugged into the socket, the LEDs and the power supply relay blinked, arming and disarming, I isolated the LED bars, it didn't solve the problem, I thought they were leaking and they really were, but it didn't solve it, the defect was in the transformer of the LP801CS power supply, cold soldering. | I fixed it and it started working again.
