Well this is interesting. I just fixed a 42" vizio, older one. Got universal replacement ballasts for it that stick to the back via magnets. New cables, etc.
Well the interesting part. It wouldn't start still. I was getting 24v to one ballast, not to the other. Swapped a main board quick and same thing.
Hooked old mainboard up and now it wont turn on voltage to either ballast.
I started getting frustrated and starting pushing the power button rapidly and it fired up....
Now working normally. Interesting creatures, these vizios. Hmm. Only thing that makes sense is I literally watched the old ic chip on the ballast smoke and burn on start up. So maybe a breaker of some sort was tripped on the psu and it reset itself?? Idk or maybe it was the usual hold the input and push power trick budm posted once. Idk
Hopefully this amuses someone as much as it did me....
