I have a hisense f42k20e that powers on and the power light flashes between red and blue about 6-7x, then a couple more times and remains blue. The panel lights up bright white then fades to black. I can see images on the screen after it fades. When it lights up there is a quick buzzing noise that sounds like it's coming from the power supply, and when the screen goes black the buzzing stops.
I took the following voltages on the LED strips:
1+ -- spike to 280v, drops to 133v
2+ -- spike to 130v, drops to 0v
I'm not sure what these voltages are really telling me. They don't match what I have seen in the past with other tvs.
