Hello. I found a Samsung WD-65638 DLP TV. Ive never had one before. When I plug it in and press power, there is no picture. The status led light is green. I hear the whining of the color wheel for a second, and the blowing of the fans, then after about 2 minutes, it all stops and the led light stays a solid red. Ive read this is the code that means the lamp is bad. I took out the lamp, and looked at it. Its black at the bottom. Does this sound like I need to replace the lamp? I don't want to buy a new lamp if this is not the case. Can someone help? Thanks.
