Please someone help. I have a samsung 4663 and when I plug it in the lamp light blinks. I hear the chimes and then two clicks. One I'm sure is the ballast and another quieter one that I don't know where it is coming from.It is behind the component connections I think. After a few seconds I hear the clicks again. This happens three times and then all three lights come on and it just sits there. I cannot shut it off, it has to be unplugged. The lamp has been replaced but it does not come on. I don't know if the color wheel is on but I know the fan is working. Has this happened to anyone else?
