    Hi, I just found this site when trying to find how to fix a backlight on a TV. It's a Soniq E55V13A (Australian ID). I've done the "flashlight test" and the LCD is fine.

    The backlight is provided by an array of 78 LEDs (2 arrays of 39). The PSU is supply 75VDC to each array, but I can't figure out what the LED voltage should be.

    Any ideas/tips on what I should do next ?

    Cheers :)
