I bought my Samsung lcd in March 2007 which means it was probably manufactured in 2006. I was watching Netflix when the tv flickered on and off as if it was being reset during a power brown out. There were brief artifacts on the screen and my home theater system displayed the HDCP ERROR message. Sound kept working, but the video wasn't coming back. It did this 2 or 3 more times over the next 5 minutes until it just wouldn't power back on anymore.
When pressing the power button on the tv, nothing happened. When pressing power on the remote, the light next to the power button would blink on the tv but again it wouldn't turn on.
After searching online I saw the common problem being the capacitors. Once I removed the cover and exposed the power board, I couldn't see any apparent issues with the capacitors. No bulging, leaking, etc. There was one capacitor that had black smearing on the top that looked like magic marker, but I remember seeing that can be leakage. So, I removed it. Upon close inspection of the capacitor, there is no swelling or damage to the top, I'm wondering if it was drawn on. I marked that capacitor in the first pic.
In the second pic, focusing on the upper right corner of the board which is a common problem area in other Samsung tvs, the caps seem ok, but there is one cap that seems to have a different substance on its surface than the one directly near it. They are wrapped in some sort of sleeve, so I can't tell what exactly they are. The only marking it has is that it is rated at 105 C. Could that be a problem as well?
