Unfortunately, that board is the inverter board. And for this model the inverter board is only supplied with the the PDP panel. The panel is quite expensive, here's a link if needed:

I wish to tell the world about the simple cheap fix for your plasma! . Please let me know if I helped. I have a 50" Plasma that deicded after a year it didn't want to turn on anymore. It just blinked red LED. Which made me see red! It took me a year to find this inexpesive fix I hope this information will be helpful to you.... These are spendy items and none of us were thinking that after a year (seems like a scam to me) the TV just won't turn on anymore.... Then they say your no longer covered under warranty or you are and they send you to some repair shop 1-2 hours away and always and I mean always tells you the part is on back order.
Lukster is right it is a power supply problem. However you don't need a new board nor do you need to pay someone a ridiculouse abount of money to fix this. I fixed mine for 40 cents.
You more than likey have bad capacitors.
Unplug the TV from power. Remove the back cover. (some models require a star srewdriver) You power supply board is right in the center. A bad cap is bulgded or raised. A good one is flat. caps have an X on the top of them. More than likely you will see a bulding or just straight raised edges on the X on the top of the caps. Cap 3300uf 10v is the ones you are looking for. Once you find them replace them with 3300uf 16v caps. If one cap is not raised replace it anyway. These caps need to be a higher voltage that why the tend to pop. 16V is plenty, don't go any higher in voltage than that.
The caps need to be soldered on. You have 2 options do it yourself or unplug all the wire harness from the board then unscrew the board take your power board (dont forget your new caps) down to a pc repair or tv repair and have them solder them on for you. It will take less than 10 minutes. I do recommend putting the board in an anti static bag. You can buy these caps at radio shack or buy them on ebay.
After you get it repaired replace your board plug all power supply wire harness back onto the board (I recommend numbering the wires as you remove them), replace the back panel cover. Plug her in and fire her up. and BAM it works. then turn it on and off a few times in complete amazement at how simple and inexspensive this was to do. Then get angry cause your repeated calls to tech support was wasted breath.

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.
