Vizio E601I-A3 dim picture and backlights flashing .

[cooper trace]

I was given this set as it was hit by lightning . Found out the Digital main was bad and replaced it . MY original main was a 0170CAR02100 and replaced it with a 0170CAR03100 . Sites said it was interchangeable . The tv worked fine for 2 days then developed a dark picture and can see the backlights flashing . Audio is fine . Wondering if the main board is causing this or my backlights are going bad . Here is a list of the voltages and resistance i've came up with . Any idea's on where to start ?

Re: Vizio E601I-A3 dim picture and backlights flashing .

Update :
I got the tv as a dead set with no power at all . Replaced digital main and the tv worked for a few days . I could see a picture but it was dark and the backlights were flashing . It ended up being the backlights . Tv works great now !
