Question about Samsung LN-T4661F 46 in. LCD HDTV
In this case, I believe it is the power supply board; more specifically the capacitors are failing. When you have the clicking problem and the long boot up times this has generally been the issue.
When you have video display problems such as shadows and lines that go away after warming up it is usually the LVDS cable and T CONN board going bad.
I had the shadow and line problem and replaced both the cable and board for $120 and that fixed my problem. Since I had the TV apart, I went ahead and replaced the capacitors so I wouldn't run into that later. You can find the parts numbers for the LNT4661F cable and board below. You can find links to you tube ( Part 1 & 2) to show how to replace the capacitors. Good luck.

It could be a faulty power supply (capacitors). To all who are having power supply issues: Samsung is now acknowledging a problem with faulty capacitors. I called 1 800 726-7864 and they said they would repair certain out-of-warranty TVs if the problem is related to the capacitors. I just called and they are sending a service rep out to diagnose the problem

I have the same TV (about 2.5 years old)
I just called Samsung Canada (1-800-726-7864) and spoke to a customer service rep who gave me a transaction # and said they will send someone out to fix the problem at no cost. it has something to do with the capacitors and they are aware of the problem.
