This is a common problem an a failry easy DIY fix.
Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.

Here are pictures of capacitors...Notice that the ones below look bloated. They have failed and will need to be repalced.

Here is the solution to your problem: http://www.youtube.com/watch?v=EbGiXqBAv...
I had exactly this problem my self on my LG 47LF66, LVD TV, with longer and longer start-up times and finally "death". The problem is due to bad capacitors on the power supply board. Its a common problem on theses TVs if you google.
I have soldered components to boards before but never dismounted parts from a board before, and I did not want to risk damaging the board. Therefor I made the simple solution of just dismounting the power-supply board with the bad capacitors. I took the board to the nearest TV-repair shop and asked for the cost of having the obviously 4 bad capacitors on the board replaced. 4 hours later and a price of about 70USD in Stockholm Sweden I had a repaired board. Mounted back the board in 5-10 minutes and the TV has been working perfectly since then (now at least 3 months).
Good luck

You can test preheting the capacitors with a hairdryer on the back of the TV. If you can possibly get the TV started again this way, then it is most surely the capacitors that are not working. The fluids in the capacitor become more effective when heated up (=similar to a regular battery). If the TV then starts up again you can be most sure that the problem is due to slowly failing capacitors.
New capacitors only costs a few dollars. Google for reputable brands. (Replace the old capacitors for capacitors with higher voltage but with the same micro-farad for improved lifespan of the capacitors).
