Pisca 2x stand-by | 1m smd resistors changed | When pressing the power button the TV generates 380v in the main capacitor of the power supply and it quickly drops to 170v, check the trigger resistors (tsound are 8 smd resistors in total with a value of 1m each) of the 12v 24v oscillator ci, in my case their values had replaced. | |

Blue LED lights up, but when the power is turned on it turns off but does not turn on, intermittent. | Lack of 2.5v voltage - 1084-25 I even left it under test for 2 days, when I went to return it to the customer without a defect, it didn't turn on, I went back to the bench and waited for the defect to appear with it open, when I went to measure the voltages I noticed that tsound was a lack of 2.5v in the mentioned regulator. | Ic 1084-25 replacement | VICTORINO |

TV doesn't turn on | Short on the y-sus board (brown board with black heatsink) | In my case the short was in the IGBT transistor rjp63k2 (q703, on the underside of the board). To find out if the short is on the y-sus board, simply remove the power cable from that board. If the TV turns on without video, then the problem is with it. | Darci Denzer |
