I've scoured this forum and several others for other E-series Vizio TV's and it seems I've got something unique going on here. I think the way this TV killed itself might grant insight into what went wrong, but I'm hoping some of the folks here might be able to confirm my diagnosis!
I picked up this TV a few days ago off the curb (a promising start, I know!) When I plugged it in everything looked fine--I had full access to the settings menu, IR panel is functional, and all of the buttons worked fine. "Why would somebdoy throw out a perfectly good flat-screen?"
I connected a computer via HDMI. The only thing notable at the beginning was that the speakers weren't working, though that may have been a configuration problem on the computer.
When I played a video at full screen the screen started cutting to black at 'random' intervals. This problem got worse the longer it was plugged in.
Things got weird when I switched to VGA.
I switched back to both HDMI ports and the same behavior happened there--random screen cutting to black for a fraction of a second before coming back up.
I left the TV plugged in but turned off for ~1hr, then turned it back on. At this point the HDMI was crashing completely and the computer was losing the TV as an input. When I tried to turn the TV off, the stand-by power cut out altogether. I left the unit unplugged until this morning.
This morning the screen is exhibiting a "2-seconds to black" behavior. After a hard power reset the stand-by power came back on. When I hit the power button the amber turns white and the "V" logo pops up for ~2 seconds, then the screen goes black and the unit cuts back to amber.
I visually checked all the caps and tested all of the fuses and resistors, nothing looks fried. Stand-by voltage looks fine, I didn't get to test full voltage (I'll need another pair of hands for the 2-second window to test that).
Like I said, let me know what you think! I won't color anybody with my own theories yet, but I'll be sure to follow up if I come up with a solution!

- If a solid black image was placed in the top left corner of the screen (about a 1"X1" square in-set about 1" from the edges), the entire screen was perfectly fine
- If the same image was completely white, the entire screen went completely dark
