Clicking starts and a tiny light on main board is flashing

Lg 55LH90 Took back off and plugged in. Clicking starts and a tiny light on main board is flashing. Disconnected all cables going to power board. Plugged in power - nothing came on. Plugged in main board cable, clicking and light flashing resumed. Does this tell me the main board needs replaced? Saw 2 capacitors of the power supply that had a bit of brown goo on their tops and seem a bit puffy at the top. Should these be replaces too?

I'm handy but not up to soldering. Can I replace the entire power supply board? Will I know what to buy when I remove the back of the TV?

Is there a schematic of the boards somewhere online?
