The lights indicate what the issue is. Kind of like your check engine light in your car tells you something is wrong with the engine.

I have the same issue with my LG 42PC3DVA and I narrowed it down to the Y SUS board. After a little research there are a few items that are prone to go. The ceramic fuses (as you found), sometimes the capacitors on the Y SUS, Z SUS, and power supply go along with them You can tell because thy will be bulged at the top instead of flat. I replaced a few of my capacitors - they are only $0.89 each so it was MUCH cheaper than a board.
The other thing that is common on the Y SUS in particular are the FETs (also called MOSFET). They can be replaced if you are good with a soldering gun but they are static sensitive so be grounded. They are also a bit tricky to test so you may want to do some research on how to determine if this is the issue... or you can just replace the whole board.

Sounds like the y sus was blown out but what cause it. Were you careful when you were checking voltages? As long as you didn't short 2 components together, your y sus should be fine. Unless the y buffer up and/or down blew them out. Even the panel could blow it.
Basically you need a scope to adjust the ramps and everything. You can adjust VA and VS with a meter. If you don't have access to a scope, then just start changing the ramps etc by eye. It might take a little bit to get but eventually you'll get it.
