I am having the same problem. Projector starts up and the main screen flashes and turn off into standby mode. Open the projector and the fans and colorwheel are spinning. Not sure if its the bulb or power supply.

Take the top off and verify that all of the fans are on, there are 2 behind the power supply and one behind the engine. If the unit lights up when the top is off, then the wires above the dual fan assy may be putting pressure on the fan frame while the top is on causing one to rub or not turn at all. If this is the case, unplug the power and try to route the cables thru the notch in the top of the fan assy a little better. If any fan isn't working, the unit will not light. This could be due to a main board problem or a bad fan itself. If the colorwheel is stuck, the unit will light and then shut off. Also, depending on the age of the projector, if there isn't a green wire going from the front of the main board to the bottom of the power supply ballast, the power supply will need to be replaced or upgraded by a technician.

Runco cl-610 projector


Likely the fan blades are dirty and out of balance. If this projector is in a dusty or smoky place you will need to clean them (or have them cleaned by a tech) often. If you are not good with electronics, I suggest taking it to a dealer. If you can get the covers off properly, you will need use a can of compressed air to carefully blow out the projector and fan blades.

When i turn the projector on the fan works and the orange light comes on but when i hit power it makes a weird noise the light turns on for a second and then off and there is no picture.


You need to check the air filter (unless it is a DLP unit) tio make sure it isn't clogged. Most projectors will shut down to avoid overheating and damaging the circuitry. At times this may also be an indicator that your lamp has reach its end-of-of life stage, and given the age and model of your projector, you may weigh the cost of purchasing a new one.

It makes a clicking noise when i turn it on and nothing comes up on the screen then it stops and the power light flickers.


something is obstructing the fan. if it doesn't spin up to speed, it'll shut down so it doesn't overheat. check your fans, and replace it if necessary.

Sharp XR-10X projector. Makes a loud whirring noise when trying to turn on. Bulb starts to turn on then doesn't. It's not the fans because I opened up the projector, disconnected the fans and it still...


the colorwheel motor bearings are starting to go. you'll need to replace the colorwheel. you can get the part from a sharp service center and do it yourself or send it to one for repair. either way, try av solutions in ny. they're really good. www.avsolutionsny.com

Dvd10 optoma projector makes a loud noise


Hi, I'm not sure if it's the same problem I had..
I had it on picture mute, for maybe 15 mins, which may not have been a good idea. While it was muted, it made a sparking sound, and then a very loud grinding noise. When turned off, the lound noise stops, and the fan continues as usual for about a minute. As soon as it's turned back on, the grinding noise is back. But the logo seemed to display ok.

I took it in for repairs, and they said they needed to replace the color wheel to fix the problem.

NEC LT260 PROJECTOR NOISE


To open this projector, you need to undo six screws at the underside of the case. That means you have to turn the projector upsidedown.
Pls note that one of these scews is a little hidden under the carrying handle.
After removing the screws, return the projector to it's normal 'up-side' up, standing position.
Remove the bulb cover srews and remove the bulb cover.
Lift up the top cover carefully starting from the front then all together.
The cooling fan is mounted very near the bulb assembly.
Carefully check the fan blades for any obtacles, wires or even a broken fan blade, that could be causing the noise.

Dramatic increase in fan noise


Hi there

If you place your hand on the machine and you can actually feel the vibration , you might be looking at a faulty Colourwheel.

If not , try cleaning the fans by blowing it out. If the problem still occurs you might have to replace the fans.
