My Samsung DLP TV has recently had trouble starting up. Sometimes the lamplight on the front will flash twice but all I hear is a clicking and the tv won't turn on. Other times it will start fine but within 10 minutes, the color gets all distorted and then the picture goes off. After the 2nd scenario, we have to unplug the tv and then when it is plugged back in, it will start up with no problems. We replaced the lamp 2 days ago but it still has the same problems. Sometimes it works fine. Others (like now) will not turn on.
