Already replaced lamp, color wheel and ballast.
A darkened band on this model is almost a certain bad optical light engine--not much else can even cause this.

First, A common mistake made is when you insert the orange ribbon cable from the Color Wheel into the DMD bd. To correctly insert the Ribbon Cable you need to look at both sides. You will see a shiny silver side and a dull black/orange side. You must insert the shiny silver side AWAY from the Color Wheel or towards the rear of the set. Now for the Ballast. When you power up the tv,Do you hear a short Buzzing sound? If you do that means that the Ballast is trying to fire up the Lamp and is working. Next, do you hear the Color Wheel spin up? If you do not then you have installed the Color Wheel incorrectly and you need to repeat the installation while making sure that you hold the rubber gasket in perfect place or else it won,t work. Chances are the gasket is in the wrong position and is binding the Glass Wheel. The Ballast is on the right side of the engine and on top of the Lamp Housing. You will see two RED High Voltage wires coming out of one end. Don't worry, there is no stored voltage in the ballast so you won't get a shock providing you have unplugged the tv from the outlet. That is the first step before you change any parts any way. Listen for the correct start sequence. With the rear backing off and the Safety Interlock Switch is being held in the up position, turn on the set. First sound you hear is a clicking which is the power on relay engageing. Then you will hear the fans turn on and then the Color Wheel spin up. Once the Color Wheel spins up and comes to full RPM then the Exciter on the Ballast will Buzz for less than half a second and then the Lamp should light up. Now if you have installed the correct Lamp and correctly installed the Color Wheel and you either are holding up the Interlock Switch or have reinstalled the rear cover and tightened all of the screws you should have a working tv.

If the color wheel you replaced was the BP96-00674A, it would have come with the proper cca adjustments for that particular wheel. You must enter the service menu and reset the cca's for proper color.
