Samsung dlp tv HLP5663W makes loud noise

Yes, the set uses a color wheel and the lamp faces it.

The wheel turns at over 8,000 rpm and is well known for this problem=bearings in the tiny motor go bad.

The high pitched or fan like noise (classic description) is this part.

Sooner or later the wheel (plastic colored segments) will shatter and set will shut down lamp and not operate---set monitors the speed of the wheel so if it slows down or stops it knows.

The part is readily available on the internet (Google the model number with "color wheel").

This can be a do it yourself repair and You Tube has video instructions for replacing the wheel by model number.

There are two common pitfalls to avoid which the instructions that come with the replacement part usually do not mention---if you decide to do this repair let me know and I will explain.

Hi. I have a Benq PB7210 and the color wheel is broken in it. I am having extreme trouble finding it. Can anyone tell me where I can buy it or if there is another model of which I can switch the color...

I would contact BenQ's web site and find the dealer list. From there you should be able to source a spare part but they may not be available as they don't break in normal service and are not a stock item requirement.
Hope this helps.

Color wheel or did i break something else?

Usually a bad color wheel will produce a high pitched sound or even a grinding noise; some sets may actually shut down if the wheel is bad or shattered.

To determine if you have a bad color wheel:
  1. Turn set off and wait for main fan to shut off.
  2. Unplug the set.
  3. Remove the lamp door and then remove the lamp.
  4. In the direction the lamp faces you will see a round opening; the color wheel is facing this opening. It is a round plastic wheel with colored segments—we want to look to see if any of the segments are missing; a shattered wheel should be clear to see.
I have also posted the general instructions for Do it yourself replacement of this part in the TIPS AND TRICKS section of this site.

I will attach a photo of the color wheel for you to know what you are looking for----
