It is most likely the power supply. If you see domed caps change them using a higher voltage cap. If it's 1000uf at 15vdc put in a 1000uf at 25 or 35 vdc. If this helps let me know.

The TV should be under warranty. Send back. Sounds like the panel is faulty (half the value of the set).

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.
