Heello Everyone Here,
I have a Vizio model# VF550XVTIA 55". The problem I have, is when I turn on the TV the vizio light goes from amber to white. It has a click sound when turning on and off. But there is NO PICTURE OR SOUND. Okay im very new to this so bare with me. I open the tv and look for sign of bad parts. Nothing that the un-trained eye can see. After just checking things out, I did notice that when removed the cable of the LG Display board (LC420/470/55WU). The bigger one of the two the back light comes on. No picture or sound still, now if i plug the cable back in the back light goes off. There is a regulator, the number on it KIA 1112 F 843. Just checking with a meter one post has no reading. I need some help here, what should the volt be for this regulator. Or maybe look in a different place for the problem?
