How do you tell if the color wheel or the cooling fan is out
When my tv went out I pulled the lamp, the lamp has no glass shards and it look like the little copper wire is still hooked to the filament. Before the TV went out it made a whirling sound, and the picture went black. When turned on the picture remains off and there is a loud whirling sound. Is it the color wheel or fan

You have a bad color wheel. The color wheel is located in front of the lamp, as the light shines through it as it spins. It is made up of different colored segments of glass, and one of the segments has came loose and causing the vibrating humming noise. The reason I know it isn't a fan is because the fans will continue to run for about 30 seconds after the set is powered off. The click you hear is the relay cutting off the fans. The color wheel cuts off as soon as you press the power button to cut the set off. I've replaced many of these at our shop for the same problem.
Great reasoning work! In fact, the lamp will not light if the color wheel does not spin-up. Fans will not stop the process of lamp ignition. Instead, a fan will be detected and a message will appear on the screen telling which fan has stopped. You need to have the color wheel replaced.
The projection lamp is gone and needs replacement. The lamp typically
lasts about 8,000 hours on high end models and 1,000-2000 hours on
cheaper models.LED technology based lamps lasts for about 20,000 hours.
Operating the TV in a warm environment without enough ventilation or at
high elevations reduces the lamp life. Setting the color or contrast to
a lower level increases the lamp life. Here's how to replace the lamp:
Turn your TV off. Let it sit there for about 5 minutes to let the cooling fan help cool the lamp.
your TV from the power let it sit about another 30 minutes.
the lamp has a cover that you will need to unscrew. Most manufactures
use a Philips head screw for holding the cover shut. Unscrew the lamp
Unpack the replacement lamp. Be careful not to tough the glass, as oil from your fingers can damage the lamp's surface.
the lamp out. Most lamps have a plastic tab or hoop on the handle that
you can use to pull it out. Follow the owners manual for specific
instructions on how to pull the lamp out. Make sure you do not touch
the surrounding lamp housing if you just turned off the TV. It can burn
you if it is hot.
After the lamp has cooled, place it into the empty box of the replacement lamp. Never put the used lamp into a plastic bag.
the guiding post also called "gutters" by some manufactures slide the
lamp replacement lamp in pushing it until you hear a firm click.
OK, THIS TV HAS BEEN A DOG,IT seems the light engine was going bad to start with so it is a good thing i diidnt replace :LAMP,or Balster,New Color wheel is working,But with BAD Light Engine Lamp will not longer come on either!
If the lamp is blown out, you will see shards of glass floating around in the bulb. The wires that connect to the glass element in the center will be "disconnected". If the set is less than a year old the bulb is under warranty. All you will have to do is contat the people that sold you the televison and tell them the bulb is blown and do a warranty claim. Good luck!
