On Philips DLPs, it's almost always the bulb or the color wheel. They actually aren't all that bad for a DLP. Be thankful it isn't a Sony.

If you get it going and don't like it, maybe you could sell the light engine on ebay. That's what I used to do with DLPs that had broken mirrors or lenses (screens). I don't know if they still sell, but they did about 5 years ago when I was listing them.

I'll take a look at the color wheel, and see if its in good shape yet or not.
I'll also take a look at the bulb again and see if its burned out or not.

UPDATE: I took the unit apart and took a look at the color wheel and the color wheel is still in one piece yet, its not shattered or anything. I took the DLP Module apart and it seems that the heatsink grease that went between the main DLP chip and its heatsink was dried up which might be why its not turning on because maybe the TV is powering down to protect the chip from overheating and destroying itself. Also I took a look at the bulb and it doesn't show any signs of cracks or being broken so the bulb is definitely still good it seems unless those bulbs fail without the bulb breaking...

I posted some pictures below of the parts in question so that you guys can see the condition of the parts in question.

That bulb is bad. Note the melted blob on the burner (the little round ball at the bottom of the glass stem in the center). If the bulb ever does fire up it wont last long before "POP!"
I have seen color wheels shatter on these, as well as make more noise than a garbage truck, and also have seen one with siezed bearings. Fans go bad too. A bulb might get yours running but it's a crap-shoot as for how long it'll keep running. Might be only days, you may get a couple years out of it. Whatever you do, DO NOT use one of the cheap, $30 bulbs they sell online. You'll regret it.

I found a bulb for this thing over at Best Buy for $94 and its a Philips bulb which I heard where the better bulbs to get for these, which I think I'm going to get that bulb once I save up some money to do so.
