Solved! Vizio M60-c3

The TV powers on, and the V logo appears very briefly and the screen does not light up further.

The TV is definitely on, and appears to be working otherwise.

Suggestions are needed as to what to replace.

System board would be the first thing, although depending on exactly how things look it may be a bad screen or backlight.
