One of the more exciting aspects of TV repair, at least for me, is repairing bad LED strips.. Mostly in LGs..
Having to pull a display panel off of a 60" LED adds a whole new degree of difficulty..
The symptom is an LED TV that blinks on, then off very quickly... Once I eliminate a power PCB issue, it's invariably an LED strip problem..
But usually it's a single strip that is bad. In some instances, 2 or more... Replace them and everything is copacetic...
But this Vizio has something I have never seen before..
This Vizio has a bad single LED in each strip. The picture has the bottom set cut off, but it's the same thing. A single LED does not come on..
Conventional wisdom says that I have to replace the entire array... But I wanted to get some confirmation that, because a single LED from each strip has gone out, there isn't any other factor at work here...
