I'll start by saying I'm not much of a techy, but my TV is dead and thought I'd pull the thread of repairing it. So keep in mind my electronics knowledge is very limited.
I've spent the last few days reading threads and doing research on what might be wrong with my TV. I did try a reflow (both heat gun and oven) of the main board based on a number of people with similar symptoms with no change.
So there is no "standby light" on when the TV is just plugged in but off. I believe there used to be but I can't be 100% sure. When I turn the TV on (touch panel or remote) I get a "click", the power indicator lights up red, fades off, lights up red again, fades off, then lights up blue/white and stays on. No screen flashes and I can't see any signs of an image with a flashlight in a dark room. I get a "click" when I turn it off.
I have a multimeter and checked P201 (power out from power board to main board) while the TV was on.

Rather than hope that my symptoms where "close enough" to others and keep tinkering, I was hoping to get advice from the experts here. Any help is appreciated. I'll add pictures in a bit.
