It will not power on. The small white light under the screen comes on for thirty seconds and goes off for one second before coming back on for another 30. It continually repeats this cycle. Tried rebooting using the Input/Down Volume while plugging it in, but no luck. I also tried a variety of other methods that I saw on YouTube for other models.

I pulled the back off and there is a small green light on the main logic board which is on.

It does not make any noise when it I plug it in, nor when I attempt to turn it on.

None of the capacitors are swollen on any of the boards.
