These Samsung DLP's can be elusive to diagnose even for a technician with a meter. You can't rely on the front panel lights to diagnose. If you don't have a meter, or never used one before, then you could find yourself guessing what is wrong. You could take the whole back off, tape down the lamp door switch, plug in/press power, watch for fans spinning, listen for color wheel, watch and listen for ballast firing, look for any signs the lamp flickers.
If you have a meter you could check the high voltage across the two pin connector going to the lamp during power on. This requires taking the entire back off, taping down the lamp door switch, using very long and pointy meter leads that can get into the lamp connector while you plug in/press power.
Besides that, lamps are designed to run for about 6000 hours. So if you run your Tv for 10 hours a day, then that is almost 1.5 years. That 6000 hours can vary depending on many factors, so you might get more or less. The first thing a repair tech would do, is replace the lamp with an original Samsung product (not any cheap knock off). That is what I would suggest for you because even if that doesn't solve your current issue, the Tv will need a new lamp very soon anyways.
