Question about Samsung LN-S4041D 40 in. LCD HDTV
Delay in turning on in flat panel TVs is mostly caused by weak and defective electrolytic capacitors in the power supply board. Most of the times they are easily recognized by their bulged top. Some times one has to hunt for them. If one can do it, it is a simple job. Good luck to you.

Just to be a little more detailed, since I just fixed this problem. It is the capacitors are the problem. However, I think that if you have some minimal skills with soldering, you can fix this yourself. You just need to take out the system board, then the power supply parts are on the top right. The bad capacitor(s) will be bulging at the top and possibly have some brown stuff coming out. The ones that go bad are 1000microfarad, 10V, however you can replace them with higher voltage. I got 35V caps from radio shack for 1.59 each. You just need to solder out the bad ones and then put the new ones in and solder. Remember that the negative end goes on the side with the bold black part of the circle on the system board. Then just cut off the extra ends of the capacitors. If you are capable of doing this yourself, you will spend at most 6 dollars instead of however much a technician costs.

SOURCE: Samsung 40" tv won't turn on
i had the same problem, you'll have to call the samsung service center. You TV's part which looks after the voltage connectivity has failed. This majorly happens due to voltage fluctuations. The part will cost around Rs. 2800 and service charges will be applied by the company.

Got to Samsung's support site and fill out a request:
You will be contacted by your regional repair center. I'm located in Milwaukee, WI and was contacted by a repair center in Elgin, IL, which is 60 miles away.
The regional center said they think it probably is a electrolytic capacitor issues, as multiple models of Samsung LCD's have this issue. They have defective (too low voltage) capacitors which will eventually give out. Unfortunately he said my model was not on the list they have for a free fix. He gave me the number to Samsung's Executive Customer Relations department, which I then called immediately. The woman there checked and found that my model indeed was covered - she updated the Support Request, and instructed me to call back the regional repair center.
I called back the regional repair center (immediately after finsihing with the ECR) and got a different person on the phone, and gave them my ticket number from my original request. He said since ECR updated it stating my model was covered they would fix it for free. If it's not the capacitors that are causing the problem I will be charged a 150$ fee, plus any parts required to fix the TV. I agreed to that since my local TV repair quoted me 200$ to fix the capacitor issue alone.
Today is January 25th, they have me scheduled to have a repair tech come to my place January 7th to do the repair.
You can fix the capacitors yourself for very cheap, maybe 20-30 bucks if you don't have anything: soldering gun/solder/flux/capacitors/etc...
I'd just go through the service request path, get it fixed for free and have a professional do it. Total time for me was 2 minutes for the service request, 10 minutes on phone for regional repair center, 10 minutes for ECR, 5 minutes for regional again. The repair is expected to take 15 minutes - most likely they'll just swap out the entire power supply board rather than the individual capacitors. Basically 1 hour of time to save minimally 150-250 dollars. I bet not many people asking to fix this make 150 bucks an hour...pretty simple math I think.

I lived with it for about six weeks, then took the back off the TV. Just now it seems to be fixed, but I don't know if it will last.
I disconnected the wire leading to the channel up/down, volume up/down and source board, turned on the tv, turned it back off, reconnected the cable, and everything seems fine now.
