When I turn my set on I can hear the fan start. I get no pic and then the green light flashes and I can hear whooping sound coming from the back. I just replaced the lamp about 2 weeks before this happend. Any ideas?

It looks like you have a weak ballast issue this is a common problem with DLP sets, this ballast board starts to wear out with time and use the lamp needs at least 150w 12vdc to turn on and if your ballast board only feeds it 120w or 130w it will not be able to turn on another thing that this ballast due is gather enough energy ( 150w ) to turn on the lamp then get weak again( 120w ) and can't maintain the lamp on and turn back off
Read the section about the red/green lights in front. It sounds like the lamp went out. Mine consistently goes out once every year to year and a half. If you plan on keeping the television, purchase two bulbs, so you have one on hand in case your new one goes out.
was the lamp blown if it was blown you could be hearing the ballast
if the lamp was not blown and the new one did not fix it the red light indicates the door there is a little switch when you put the door back on if you look at it it may need to be adjusted so it will connect with the door if that is not it you could have a fan that is not turn if it is making a real loud constant humming noise while it trying to fire the lamp you probably have a bad color wheel
