Question about Samsung 46 in. LCD HDTV
It will often take the tv 15-45 minutes to come on..it sometimes comes on with a faint picture behind a lot of noise and makes a squealing sound but will finally start after some time of cutting off and on...it also seems that one of the HDMI inputs does not work most of the time and we have to switch locations for the input
Yeah, you most likely have the same TV I do. I changed the capacitors and it kind of helped.. I discovered the problem is with humidy and rainy days! Is your TV near a window? I ordered a screen power inverter but just moved the TV upstairs and away from excessive humidy and its been fine ever since. I might still put the inverter in eventually.

if you have a cable box then it is probably the resolution settings in the cable box, what type of cable box do you have

there is a soloenoid type switch that fires the TV up this has failoed. its like a neon or fluoresecent tube that has a faulty starter switch light tries and tries but never quite makes it when it does get going it has that purple smear in the tube. that is the simple explanation for your problem. part is about $60 labor is unkinown as i am not in USA but looking at some of the rip off charges I am glad i dont have the bill

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.
