Well, I can't speak for anyone but myself. I could change a board with no problem, it's mostly just screws and ribbon connector(s); but I was an electrician in a past life, and an electronic hobbyist as a teenager.
The issue with swapping a board is that there are no Y boards available from Samsung. They used up all the spare parts pushing out TV's at the end, and few parts are available. The Y board is in especially short supply, although I think a few people have gotten them off eBay, out of F8500's that had cracked panels and etc.
In the thread, a source of the capacitors is identified (I think it was the Mouser parts company), and people have been buying the capacitors and replacing them themselves. I actually bought a couple of sets to put in a drawer in case I ever need them someday.
Having a TV repair shop replace capacitors should also not be very expensive.
But you should have confidence that is the problem before tearing things apart. You "might" be starting to get affected by that problem. There is a LOT of info in that thread.
EDIT: There actually appears to be some boards on eBay now, IF I am interpreting the offerings correctly. If one was to go that route, one would want to take the back off the TV and copy down the part number, and make sure to get that exact part number.
