    Hello,

    I received a TV in which the backlight did not work. After that I disabled the protection (pin 11 with 10k ohm to ground), the TV worked for 2 weeks, now it has the same error. I have redone the solder joints and replaced the 10k ohm resistor with another 10k ohm. Unfortunately it does not work. Does anyone have any ideas? LED driver: OZ9976GN

    Questa Tv non fa uso di led per la backlight ma delle lampade CCFL. Togliere la protezione e lasciarla permanentemente non è una buona idea in quanto al deteriorarsi le CCFL si rischia di distruggere i trasformatori. Di sicuro andavano cambiate le lampade CCFL ormai esauste.
