Default Re: Sony Bravia no picture but backlight on

I have a Sony KDL-52W4100 a little less than 2 years old. I turned it on and after 30 seconds heard a pop and the picture went out (back light still on) and the red LED flashed 14 times( Panel Error I believe). After reading through this and numerous other threads on the issue decided to look at the fuse on the TCON board. Before I even checked the fuse I found what appears to be a burnt capacitor (pictures attached). I have ordered a new board from Sony and have a couple of questions. Do you think this is an issue with the board, or should I check another component before putting the new board in only to have it happen again? I have seen that heat is a real issue with the board, is it OK to put heat sink grease on the pads to ensure better transfer or are they good enough as is?
Thanks for the information, I wouldn't have gotten this far with out it.
