My tv is a 50in lg plasma. The power supply fuse will blow evertime I plug in the tv. Replaced the fuse and plugged it in to the power supply with all other plugs to surrounding circuit boards disconnected and it still blew. Does this mean I have to replace the circuit board or the power supply?
The power supply board is gone. You can get parts from here: TV Parts Universal TV Stands DLP Chips ShopJimmy

If you just bought it call where you bought it and tell them they need to send a repairman out to fix it.

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.

Use the audio jacks in the Monitor Output section. See pages 9 and 19 of the manual:
