My Samsung HLP4663W 46 in was making a buzzing noise for several months. I know it could have been either the fan(s) or the color wheel, but I never opened it up to determine which it was. Now the TV quit working, and nothing inside is making noise. When the power is pressed, the sound will come on for a while then turn itself off. The LAMP light flashes, which the manual says indicates the bulb needs replacing. My Question: If the bulb went out, would the color wheel and fans stop working until I replace the bulb? I'd hate to replace the bulb and find out it is something else entirely.

I have just inherited a samsung HLP4663W, It had a color wheel that was making noise. I have replaced the color wheel. Now I am getting a fan speed warning. it will come on but shut off after approximatley...

You have 4 different fans inside of your TV. The biggest challenge - to pinpoint which one is bad. I would recommend just to get 'em all and replace 'em all. They will start fail one after another anyway.

I have the dreaded buzzing noise and no picture. Would a broken color wheel alone cause this or do i need to replace the bulb as well?

The buzzing noise is usually related to just the color wheel for your model.

Need to check the cooling fan.
-- open the back cover & unplugg two of cooling fan socket(black & red wires or yellow & red wires)

If the noise still remaining, need to exchange the color wheel.

Samsung DLP HL-R4266W..no sound or picture. TV is completely dead

Assuming the noise is a high-pitched whine, then yes, it is the color wheel. If the color wheel goes out, the TV will turn on for a while, then turn off when it can't establish color wheel sync. The color wheel has to be in sync with the mirrors on the DLP, so if sync can't be established, the TV turns off.
You can order a new color wheel from Sears or partstore.com (among other places) and replace it yourself, if you are so inclined.

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.
