HI HAVE A LG 42PW450T , WAS NOT COMING ON ,, CHANGED THE YSUS BOARD AND IT CAME ON WITH A LOUD BUZZING NOISE, AND IT WAS GETTING HOT ON THE SIDE OF THE YSUS, SO THOUGHT I,D DO A FACTORY RESET, AFTER I DID THAT THE TV DID NOT COME ON AGAIN ,, ACCEPT WHEN I UNPLUG THE YSUS BOARD , CAN SOME TELL WHAT CAUSING THIS AND HOW TO FIX IT
MANY THANKS

Hi,
you need to change the Ysus and buffer board all together and don't overlook the panel too.
All the best.
