good grief - my TV just did the same thing - its locked in standby mode - I disconnected power several times - each time i reconnect the green light comes on for about a minute 9nothing happens on the screen) and then returns to the stanby mode

Yes, i would get it checked first to make sure it is the backlight, if you can see a slight glow around the edges then the backlight is working.

You will have either a fault with the Y-Sustain board (this I would assume from your description is the board you changed the fuses on) or the buffer board which is the long panel to the left of this board. It is probable one of the drive ICs on this board has blown & a replacement board is the best solution.

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.
