Either the lamp is only half way in and burning the socket, or your color wheel needs replacing.
Hold the lamp door switch down and turn on the TV looking at the lamp see if it buzzing near the lamp(burning).
If the lamp lights and the buzzing is up front or middle of the TV, its a broken colorwheel.
The colorwheel goes bad from the lamp heat and from spinning at 10,000 rpms.
here is directions for replacing it click here
Let me know what you need from me
Will be back later
Hard to say, are you sure the lamp is all the way in, screw that holds it in tightened?
Remove the lamp and slide it back in , noticing the socket as you slide it in, is it going all the way in? whe you tighten the screw is the lamp flush and snug behind the screw?
If yes , then i would say you probably need a color wheel, can you see the color wheel fins behind the lamp, look through the hole with the lamp out, if the fins are gone the color wheel is shattered and needs replacing.
Here is a similar photo from a toshiba DLP
Its a bad color wheel.
A tech would charge about $350 installed.
Or you can try yourself
