Ok since you say you have already checked the cover switch I would suspect that it is a temp sensor issue. I would however first recommend that you retry the lamp replacement as it can happen if the lamp is not seated properly in the housing or the screw that tightens on the cover of the housing(not the one near the door switch). Try it and let me know if problem persists and I will tell you how to proceed.
Ok. THanks for the clean explanation of the situation. I think I know what the problem is. See if the LEDs on any of the boards are coming on, especially the analog board. Mark the location(like OP 102) and let me know.
I am not talking about those on the Side. THis one is located INSIDE the tv ON the analog board. The service manual lists that if the lamp does not come on and the door switch is OK , then the LED at OP101 on the analog board will come on. See the troubleshooting section flow chart.

If you have replaced the Lamp and TV Fails to work, then you also need to check the Fans and make sure they are OK. If Fans are OK then Repalce the Ballast Board.

Samsung Parts.com 1-800-627-4368 Ballast Board is what powers Lamp ON.
Does Lamp Light up and stay on and Do you have Picture and sound ,or No picture but sound?
Let me ask you this ,do you still have the old Lamp and have you tryed using it and not the new Lamp ? If you have do you get the same results?
While you are trying out the old Lamp, Make sure that No one has left something unpluged to boards?
I was wondering have you been able to Fix your Set?

I have checked and both fans are running, lamp is working all the time now and screen of TV looks like it is trying to power on but just keep on flashing slowly.

lamp as a lamp is lightening all the time but a projection of that light to lcd screen is not continuous. I checked sound and NO even sound is not present...
lamp is lightning all the time but projection to lcd is not continuous...and NO there is no sound too
I still have the old one but I am not sure isthere any difference between those two because I get that TV from my cousin who allready was in a service and they told him that lamp is burned... so I will try the old one now...
I tried with old one but nothing...wont work with old one and now I put back new one and it is lightening but nothing on the screen ...nothing at all...I paid attention to wires and checked all once again...
Do you want to say that lamp has to be in a perfect position? Because the lamp works all the time but projection falls... I have allready try to bridge contacts of the temperature swtch which is placed above the lamp,between a lamp and the fan and same result I get... But i suppose that problem could be in "safety group" because when I turn on the TV and look at the signal LEDs they acts like this... at first there is "lamp LED" lightning, "picture LED" is blinking,and "standby temperature LED" is turned off !
In my service manuall that is described as OK-picture should come at 20 seconds... BUT after few seconds "standby temperature LED" turns itself on and then all three LEDs start to blink slow but continuously what is described in the manual like "replace the lamp" !
I checked everything but there is no other LEDs except those I talke about ( on the side of TV ) even those smallest...
No,not yet but maybe I am closer to solution of my problem ! I suspect that "remo" some kind of optic lens dos not read the light which is given by lamp... does that effect to LCD card which drives LCD projector? Because the lamp is working but there is no projection to screen
