Why won't my tv show picture and my bulb is still ok?

What should I look at if my bulb is still good and the screen is still black?

Samsung Slim DLP model#: HL-T46758, there is also another number on the front: BP68-00633A I'm not sure what that one is exactly tho. No lights or any kind of picture show up. I've checked the color wheel, bulb, and today I took out all the back electronics, so the inverter which has all the plug in ports connected and the projector part where the bulb connector, color wheel, ballast, and fans are located. The wire in the bulb is still in tact and the color wheel is just fine. I'm thinking it might possibly be the ballast that's the only place I see that is a little abnormal. On the board next to the black box component are 3 resistors. 2 are in a vertical line and the other is across from them by it's self. I believe they are called C1-C3. The two that are by eachother look kinda worn and board a little white around them. The tv has been serviced before and the other resistor looks newer like it's been replace already.

Also the cables that connect to the bulb housing look a little fried I'm taking it to my work today to get a better look inside.
