Vizio TV Repair

We've been seeing many 2014 E550i-B2, E550i-B2E Vizio TVs with intermittent symptoms. The set will play work a while and then the picture will go out with the sound working. Or Both picture and sound will go away. Turning it off and on may get it to work again for a while.
This is a same day repair in most cases.

We've been seeing a lot of Vizio M550SV Smart LED TVs with problems of no sound, no audio on any input. These are good sets and were made in 2011 and 2012. The problem is on the audio section of the main board. There are 5 components on the board that need to be replaced for this repair to last.
