Question about Vizio E470VA 47 in. HD-Ready LCD TV
The TV slowly began to degrade. At first the TV would turn on and you had a picture and sound then it would turn off. After a while it would turn back on. This slowly got worse to a point that you heard some crackling noise and then no sound. TV will now only illuminate logo but will not show a picture. Your help is greatly appreciated.

This is the second time I have seen this problem this week. Seems like a common issue on Vizio LCDs. Anyways the problem you mentioned indicates that the tv-micro IC has failed. THis is located on the main audo/video board and a component level repair is not possible in this case. The main A/V board has to be replaced and it should cost you around 100-125$. Would you like to do it yourself?
