Device On but No Image
If the projector is turning on but not displaying an image, this issue could be a cable connection or signal issue.
Connection is Unrecognizable
If the message “Input Not Supported” appears, this could be caused by the projector not recognizing the internet connection. First, double-check if any cables are loose and ensure they are securely connected. If the issue is still occurring, confirm the correct input is selected. To do this, press the Menu button and search for the list of options.
Signal Issue
If the projector is not showing an image but is on, the signal cable may have a connection issue. A yellow flashing light indicates this. First, check if the VGA cables are correctly connected to the projector and your computer. Ensure the Input Signal setting is set to RGB or Auto and check the correct source (Computer1 or Computer2) is selected.
Projector Turns Off Suddenly
If the projector keeps turning off suddenly while in use, it could be a menu setting, a power supply issue, or the result of overheating.
Standby Mode On
If the projector is in Standby Mode, the projector can turn off suddenly. Change Standby Mode by pressing Menu, selecting Extended Menu<Standby Mode<Communication On.
Faulty Cord
If the cord is damaged, it may cause the projector to turn on and off. Inspect the cord for any damage (i.e., frayed or disconnected wires). To make sure the cord is functioning correctly, test the outlet. To test the outlet, plug in a different working device to ensure the external power supply is working correctly. If the power outlet is working, replace the cord.
Overheating
If the projector is overheating, it will shut down. Refer to the “Projector Overheats” section in this troubleshooting guide for additional information.
Projector Overheats
If the projector is overheating, it could shut down suddenly. A number of issues could cause overheating, including: a blocked vent, clogged or damaged filter, or a faulty fan, or exposure to an external heat source.
External Heat Source
If the projector is exposed to prolonged sunlight or is too close to a heater, overheating could occur and cause the projector to shut down suddenly. Be sure the device is removed from external heat sources.
Clogged or Damaged Filter
Overheating can occur if the filter inside the air filter cover is clogged with dust and dirt. To clean the filter, slide the filter-cover opener and lower the air filter cover. Remove the filter from inside the air filter cover and gently clean with compressed air to remove dirt and dust. DO NOT GET WET. The filter membranes will become damaged if exposed to liquid. If a filter is torn or exposed to liquid, it is damaged. Replace the filter.
Vents are Blocked
If dirt or other objects obstruct the projector vents, it will overheat. Make sure the vents are clean and unobstructed to prevent overheating. To clean the vents, use a long-bristle brush to carefully wipe the dust on the vents. It is suggested to clean the vents periodically, or if you see any dust on the bottom or the side of the projector, wipe with a soft cloth.
Faulty Fan
If the fan is faulty, it wont cool the projector and the device may overheat. If the fan is making excessive noise, it could be old or loose. Replace the fan.
Projector Image is too Dim
If you are having trouble seeing the images because they are not bright enough, you may need to adjust your brightness settings, or replace the lamp on the projector.
Brightness is Set to ECO Mode
If the projector’s brightness setting is in ECO mode, the projected image may be too dim to view clearly. ECO mode is the low light setting and will cause the device to power off after a period of no activity. If the image brightness is set to ECO, adjust brightness in the settings menu by pressing Menu and selecting Power Consumption > Normal.
Lamp has Exceeded Lifespan
If the projector’s image is too dim to view clearly, the lamp may have outlived its lifespan. After 2500 hours of use (3500 hours in ECO mode), the lamp dims. Check the hours of use by pressing Menu and selecting Info. If lamp usage is at or exceeding 2500 hours (indicated by a flashing red light), replace the lamp.
Projector Image Quality is Poor
If the image projected appears fuzzy or unclear, it could be an unadjusted focus lever, a dirty projection window, a damaged lens, improper menu settings, or incorrect signal settings.
Unadjusted Focus Lever
If the focus lever is not adjusted, that can cause the image quality to be poor. The focus lever is on the side of the projector next to the air filter. To adjust the focus lever, you slide the air filter-cover opener to open the air filter cover. Then, you can lower or raise the focus lever to clear up the image.
Dirty Projection Window
If the projection window is not clean, it can cause poor image quality. To clean the projection window, you can use a cloth to wipe the glass. DO NOT use chemical sprays/materials as they can damage the window. Chemical sprays/materials can include alcohol, wax, paint thinner, benzene, and other cleaning products.
Damaged Lens
If the lens is scratched or cracked, it will produce fuzzy or unclear images. Replace the lens.
Improper Image Menu Settings
If the settings on the Image menu are incorrect, they can cause the image quality to be poor. The image menu allows you to adjust the sharpness, brightness, color, contrast, tint, and the Auto Iris settings. To change the settings, first press the menu button. Then select the image menu. After this, you adjust various options.
- Auto Iris Settings: If you adjust the Auto Iris Settings, it can change how much light gets into the imaging sensor. The image sensor helps to balance the exposure, which allows the device to adjust the brightness of the image.
- Brightness: If you adjust the brightness, it can darken or lighten the image display.
- Color Adjustment: This changes the color values in the projected image. To adjust the color, select “Abs. Color Temp.” to change the value from 10000 °K (blue) to 5000 °K (red). If you wish to adjust red, green, or blue, select the color and then adjust the hue and saturation. Note that this will not be available if the sRGB is set on the Color Mode Setting.
- Color Mode: If you adjust the color mode, it changes the brightness and color. Note that you can save a different setting for different sources.
- Color Saturation: If you adjust the color saturation, it changes the depth of the color of the image display.
- Contrast: If you adjust the contrast, it makes differences between the dark and light areas on the image more or less distinct.
- Tint: If you adjust the tint, it balances the magenta (purple/red) to the green of the image display.
- Sharpness: If you adjust the sharpness of the image, it changes the clarity of the image. (Less fuzzy or pixelated)
Incorrect Signal Settings
If the settings on the signal menu are incorrect, it can cause the image quality to be poor. You can change the projected image's position by correcting the sync and tracking for the computer images. Or you could change the aspect ratio. First, press the menu button and select the signal menu. Then adjust the signal menu options.
- Auto Setup: If you adjust the auto setup, make sure to leave this setting on. This is for automatic optimization of the computer images. Turn this setting off if you would like to save the changes you made for Position, Sync, and Tracking settings.
- Aspect: If you adjust the element, it changes the image aspect ratio: the ratio of the image width to height.
- Input Signal: If you adjust the input signal, it changes the colors on the auto setting. Select the specific setting for the equipment connected to the ports Computer1 and Computer2. Afterward, choose the RGB for your computer, RGB video connection, or auto for a video player.
- Noise Reduction: If you adjust the noise reduction, it can smooth the rough-looking images. For this, you want to experiment with the settings. Only turn this off when viewing low-noise external sources.
- Position: If you adjust the position, it changes the centering and the cut-off sides of the image. Select the setting, and you can use the arrow buttons to center the image.
- Progressive: If you adjust the progressive, it changes the interlaced signals in the progressive signals. Which is best for moving images. This is for component video, composite video, and S-Video. Turn this off for the still images.
- Resolution: If you adjust the resolution, it changes the detailing of the image. To do this, select the auto setting for the projector to identify the resolution of your input signal. Select wide for the widescreen images, or select Normal for the 4:3 or the 5:4 ratios.
- Sync: If you adjust the sync, it corrects the flickering and blurring of the image.
- Tracking: If you adjust the tracking, it alters the visibility of the vertical stripes in your computer images.
- Video Signal: If you adjust the video signal, it changes the connection of the video port. To do this, select your equipment type in the Signal Settings menu. Keep this setting at Auto for most of the time. Turn this setting off if you use a 60-Hz PAL system, and change the setting to PAL60.
