It seems that the back light is malfunctioning or needs to be replaced the fact that it turns off after a few seconds indicates that is getting over heated. All LCDs, Plasmas and Projection TVs come with a shut off switch witch will turn of the monitor when a spike on the temperature is detected this is to protect the system from overheating. Now before you think about send it for repair; is it well ventilated? Does air circulates around it? Good luck!

This just means that your bulb is going out. My friend and I replaced his and it was really easy. I am recommending the company we got it from, because their excellant customer service. they walked us through the entire thing. just go to DLP lamps .com

take off the lamp access door on the back and find the safety switch that the door pushes on. unplug the connector from the switch and put staple into the connector to short out the cable. Switch is probably bad. worked for me. same problem.

Not knowing the specific model for your Samsung TV and how old it is, I can only offer this possibility because I've encountered what sounds like the same problem. Certain models of Samsung HDTVs around 3-4 years back have a design problem with their power supplies - they put in the wrong size capacitors (aka "Caps"). After a few years, the capacitors fail, and the power supply also fails. I think it's possible to replace individual capacitors, but most likely you will have to replace the power supply. Unfortunately if it's out of warranty, it will cost several hundred dollars, especially for a home / onsite visit. There is a visible symptom - from 2-6 capacitors on the power supply board will bulge out, as shown in this pic:
You might try calling Samsung customer service and tell them you are aware of problems with their power supply design, and try to get them to repair the TV for free, especially if you are just out of warranty.
