Frequently Asked Questions

Q My projector is not working when I turn it on?

A

Make sure the outlet in which the projector is connected has power, and that the projection lamp is good. Some projectors also have "indicator" or "status" LED lights on the control panel. If this light is on or flashing please refer to your owner's manual for solutions and explanations.

Q I'm getting no signal or picture?

A

Upon setting up your equipment it is very important that you turn on the projector first. You will see a blank projection image, now turn on the computer, (confirm your cables are connected properly). When using a laptop computer you may need to disable your computer's display screen. First locate the "function" key at the top of your keypad that reads "LCD", "CRT" or it may have an icon that resembles a computer monitor.

Q My screen is scrolling or I'm only getting a partial image?

A

This is normally caused by the computer's resolution not being completely compatible with the projector's resolution. You will need to adjust your computer's resolution to match the projector. (the projector's resolution can be found in the "specifications" page of the projector owner's manual.) You will be able to access the computer's resolution and make changes by performing the following steps:

For Windows - Go to the "Start" icon on the desktop area of the computer and click. Select "Settings", "Control Panel" and then click on "Display". Choose the "Settings" tab and locate the slide bar that represents the computers current resolution. (example 1024x768) Change the resolution to match that of the projector and click "OK".

This can also be caused by the signal being displayed on both the computer's (laptop) LCD screen and the projection screen. If you are getting poor results even after resetting the computer's resolution try to "toggle" the image by using the steps shown in the " I'm getting no signal or picture" section above. Your best results should come when the image is on the projection screen only.

Q My remote control will not work?

A

Weak or dead batteries can cause numerous problems with a remote control. To maximise the life of the batteries take them out when the projector is not in use. Some projector remotes come with an "on-off" switch for the remote itself (not to be confused with the power button for the projector) turn the remote off when not in use. You should have a clear line of sight between the remote control and the projector's inferred receiver. Any obstructions will interfere with the projector's ability to pick up the remote's signal.

Q What is "Hertz" in reference to how the "Refresh rate" affects the displayed image?

A

"Hertz" is a measure of frequency in cycles per second ("Hz" abbreviation for "Hertz"). The "Refresh rate" is the number of times per second during which a displayed image is regenerated, expressed in Hz. For example, a refresh rate of 60 Hz means that a displayed image is regenerated 60 times per second.

Q Why do I need a video amplifier when using a VGA cable that's more than 10 metres? What will happen if I do not use one?

A

A video amplifier will strengthen the RGB analog signal that is transmitted from the display adapter. Otherwise, the control circuitry in the projector cannot tell what kind of signal it is, especially sync signals. If a video amplifier is not used, image distortion (poor image, shadowing, lack of colors) or sync problems may occur.

Q I am using a projector and the projected image doesn't look very good. What's wrong?

A

Most new projectors have an automatic setup ensuring that the projector matches the computer resolution. However, in some cases the adaptation process may somewhat impair the quality of the image or fail to find the correct resolution. If you're not sure of the resolution of your projector, just change your computer display settings and see if the image improves. Although most projectors will project an image when the computer is set to a different resolution, the quality of the image usually deteriorates

Q The entire computer image does not appear on the projector - the bottom of the image is cropped or the projected image exhibits poor quality text?

A

Set the computer resolution to match the projector's native resolution. With some laptop computers, it is necessary to disable the laptop display to attain this resolution, especially when the native resolution of the laptop display exceeds 1024x768 and the projector's native resolution is 1024x768. If you are using a laptop computer and the projected image is still cropped or distorted after changing the resolution, you will probably need to completely disable your laptop display so the image is shown only on the projection device. Most laptops use a function key or combination of key commands to disable/enable the laptop display.

Q What is the life expectancy of the lamp?

A

Average lamp hours range from 1,500 to 2,000 hours although new lamp technology promises 6,000 hours. The lamp life of different projectors varies. Most projectors use a lamp hour counter to track the number of hours of lamp use. Check the projector's on-screen menu to determine the number of lamp hours used. After so many hours of use, the lamp life LED on the projector illuminates or the projector simply will not ignite the lamp, indicating that the lamp should be replaced. Lamp life will vary dramatically depending on the use and environment that the projector is used.

Q My projector is ceiling mounted and my remote works inconsistently?

A

The first thing to do in this case is to check the batteries. Inconsistent IR remote performance is often caused by insufficient battery power. If the batteries check out OK, there is also the possibility that you are exceeding the recommended maximum operational distance of the remote control. Finally, another common cause of erratic IR remote behavior is interference from fluorescent lights, which may need to be turned off during the presentation.

Q The image produced by my projector has purple or magenta dots on the screen. How do I correct this?

A

Purple or magenta dots are the result of dust or dirt particles that have settled on the green panel. The solution is to clean the green LCD panel; this should only be done by an authorized technician. Please call 1300 302 884 for assistance. Regular maintenance of the air filter will reduce the likelihood that this problem will recur

Q My projector powers off erratically. What is causing this?

A

This problem can be caused by improper seating of the lamp assembly. The solution is to re-install the lamp assembly correctly. Please consult your owner’s manual for instructions on replacing the lamp unit and re-installing your existing lamp. Also, dirty dust filters can cause the projector to overheat – clean the dust filters. If the problem is not corrected by doing so, then the projector may need service. Please call 1300 302 884
