Dear David,

i have Optoma projector HD72I color wheel,
please patiently wait for some days, once i post it on Ebay, i will inform you at the first time.
lets keep in touch with freely,
best regards,
Jack

Hi try to check this link. http://www.uktvparts.co.uk/ , http://www.shopjimmy.com/ , http://www.tvrepairkits.com/ good day and best regards.

It is not the smartboard, lamp or the computer as well know, it's the projector itself. This may not work but you at least need to try press the auto adjust button on the projector and then adjust the clock/phase in the menu. If not you will need to send in to NEC it could by the color wheel. Usually they have a warranty for a couple of years.

Simple answer No! Colour wheels do run at high speed (I think around 20,000rpm and you can get 4 and 6 segment colour wheels i.e for each colour.to get better colour definition for the higher end ones.

Remember the colour wheel is a precision device as It has to rotate in sync with the DMD chip as each different frame of colour information is sent to the dmd chip.
some important considersations for choosing another colour wheel- off the top of my head:
motor voltage and current
number of poles on stepper motor
size of motor- will it fit
diameter of colour wheel
purity of the colours etched onto the glass
mounting of the assembly

I'd be looking for an original, see if your authorised repaired would be happy to sell you a genuine one on the basis of no warranty no return.

but do give it a go if the repair cost and a genuine one is out of the ball park or similar cost to new
Good Luck!

check the colour glass wheel is shattered with a piece of glass still stack to the wheel. it not even thats why it vibrates

A DMD has no inherent colour capability - it's just a configurable mirror array. If you want to do full-colour projection, then, you'd expect that you'd have to use three DMDs and three coloured filters - red, green and blue.
But if a single DMD's switched in synchrony with a rotating "colour wheel" - a spinning tri-colour filter that lets through red, green and blue light in turn - then the very rapid switching speed of the DMD lets it lay down red, green and blue images in such fast succession that the result is a perfect colour image.
You can do the same trick with a single LCD panel, but it's not a good idea; LCDs are transmissive, rather than reflective, devices, and block something like half of the light that tries to get through them. To maximise brightness in LCD projectors, a three-panel design works better. If you try to pump the entire output of a super-bright lamp through one LCD, keeping it cool becomes rather challenging.
The extreme smallness of the moving parts on a DMD mean that it behaves like a solid state device, not a mechanical one. For all their complexity, DMDs have very high Mean Time Between Failures (MTBF), and well-made projectors based on DMDs can be expected to last easily as long as LCD units, and probably longer. If a DLP projector fails, it's not at all likely to be because there's something wrong with the DMD.

It's the lamp. The same exact thing happened to me, my projector started making a loud whinning noise and the picture quality got really dim. At first i thought it was the fan too but after alittle online research i found out that that when the lamp bulb shatters it does this, so i went a got a replacement and it fixed all the problems. :)

We are able to source these colour wheels from the suppliers as we are authorized service agents for Infocus.

they are easy to replace. however, infocus doesn't sell them anymore.
