Makes noise around light and will not come on.


yes a broken color wheel can prevent a set from powering up but a broken lamp could also shatter and have pieces near the color wheel.

Replaced the balast, tv not longer turns on and off but now it has a kind of pulsing picture. Am I looking at a new bulb? a new color wheel ? or some other surprise that I haven't heard about?


Lamp is possible especially if the ballast was bad--it powers the lamp.
Color wheel will usually display some issues--high pitched whine or fan like noise---with the lamp removed look where it faces--color wheel is there--any broken or missing pieces and it is the problem---

The wheel is directly connected to the set---set will detect if wheel not moving or moving too slow etc and almost instantly turn the lamp OFF.

It not bringing out color.it showing black and white


HI,
I will need some clarification as to the model number of your projector to best help you but in general if you have a DLP type projector & suddenly lose all color to your image then the color wheel has failed by burning out or breaking. The color wheel sits directly in front of the projection lamp & if you take your lamp out you can use a flashlight & point it in towards the spot where the light comes out of the lamp & look at the color wheel. The color wheel has 4 to 6 different color pieces called segments like yellow, red, blue & a clear segment. You will be able to see if the color wheel is broken.
If it is you need to have the unit serviced. If you're handy you may be able to order a new color wheel. They are usually around $100. There can be other causes as well but the wheel is the first place to investigate. Please let me know if this was helpful.
Thanks & good luck,
Jim

Broken color wheel


Something between 150-200$. In my opinion it won't worth it. Go and get yourself a brand new one...

Color wheel failed. Can I fix it myself??


If you contact Optoma and they have the part available then, yes you can fix it yourself. You have to be good at taking things apart and remembering how they go back together. Changing the color wheel assembly is not that hard.

Black and white picture only


The color wheel is not the problem. If the spinning color wheel is impaired in its RPMs it will cause picture distortion, not black and white picture. If the color wheel looses any of its color fins, like if it is broken, there will be a loud vibrating noise inside the tv which you did not mention. Also if the color wheel is broken and doesn't spin, the tv will not start up.

The likely problem is on the digital control board or the power supply and should be referred to a local repair shop for repair.

There is an outside chance that you will receive color if you experiment with using all of the different input ports to see if you can find one that will bring back color.

I heard a pop and now the projector only shows black and white.


The color wheel has failed in youtr projector. There are 4 pieces of glass in the color wheel which fit togeter in a "pie" formation and they are red, blue, yellow & clear. This wheel is spun by a motor. The glass is glued to the motor's hub, and, when it fails the glass segments are thown off the hub. This gives you a B&W picture because all of the light is allowed to shine through the optics all of the time. Replace the color wheel with Toshiba part no: 23125963. It will be about $65. No soldering is involved, just use care with the ribbon cable to the motor. You will need a no. 2 phillips screwdriver and a set of jeweles screwdrivers to do this.
