I have a Samsung LCD ('06 vintage) that wouldn't come on after a week of taking a few minutes to start every time. I opened it up and immediately saw 4 blown capacitors (fairly large ones). Realizing they were part of a separate power supply board, I managed to find the board online for $90 and replaced the whole board. Six months later or so, the TV popped and turned off while I was watching. Instead of replacing the board again, I just found similar spec capacitors from Radio Shack and soldered them into the old board. Swapped the old board back in, and it's been working for several years now.
You might try searching the exact model number online. You'd be surprised at what you'll find. Often the repair help will cover a fairly broad range of models as the physical layouts are similar and the only real differences are in the firmware (the pre-loaded menu and signal processing software).
