Troubleshooting Common Issues with Ultra Short Throw Projectors

Ultra short throw projectors can have their shortcomings, especially when they are used for a long time. Here are the projector troubleshooting steps for your projector issues if it develops any of the following technical glitches:

Projector Hardware Issues

Your ultra short throw projector may develop a few hardware issues, which should be straightforward to diagnose and rectify. If you're wondering why your projector is not working, here are some common hardware issues and how you can solve them:

My projector won't turn on or power on

  • Ensure you've securely connected the power cable to the projector and outlet. If unsure, plug in another device to ensure the current flows.
  • Check if the projector has a power switch and turn it on. If the projector has a removable battery, ensure that you properly insert it or try replacing it with a new one.

Remote control is not working

  • Check the batteries in the remote control and replace them if necessary.
  • Ensure a clear line of sight between the remote control and the projector.
  • Check if an obstruction or interference near the projector may affect the remote signal.
  • Try using a different remote control to determine if the issue is with the projector or the remote itself.

My projector is overheating

  • Ensure that the projector has proper ventilation and there are no obstructions.
  • Regularly clean the projector's air filters to prevent dust from clogging them.
  • Reduce the brightness or other settings that may be causing excessive heat generation.

Projector fan making noise

  • Check for any obstructions near the fan vents and remove them.
  • Place the projector on a stable, level surface to prevent vibration.
  • Clean the fan vents and the projector's internal components to remove any accumulated dust or debris causing the noise.

No audio coming from the projector

  • Check the audio cables and connections to ensure you've correctly connected them.
  • Verify that you've correctly connected the audio input source to the projector.
  • Adjust the volume settings on both the projector and the connected device to ensure they're not mute or set too low.
  • If the issue persists, connect external speakers or audio devices directly to the projector's audio output to isolate the problem.

Projector Picture Quality Issues

Projector Picture Quality Issues

Sometimes, your projector display may fail to offer the quality you anticipate. You can use these troubleshooting tips to eliminate this slight inconvenience. 

No picture on the screen or "No Input Detected" message

  • Check the connections between the projector and the input device (e.g., laptop, Blu-ray player). Ensure you've securely connected the cables.
  • Verify that you've selected the correct input source (e.g., HDMI, VGA) on the projector.
  • Confirm that the input device is on and transmitting a signal.
  • Try a different cable or input source to eliminate cable or device issues.
  • Check if the projector's lamp or LED light source needs replacement or a warm-up period.

Blurry or not sharp image

  • Adjust the projector's focus and ensure the image is in focus.
  • Check the projector's distance from the screen or surface. Ensure it is within the specified throw distance range for optimal image sharpness.
  • Clean the projector lens using a soft, lint-free cloth to remove dust that might disrupt clarity.
  • Grainy image.
  • Ensure the input source's resolution matches the native resolution of the projector. Use the recommended resolution settings for the best image quality.
  • Adjust the projector's picture settings, such as brightness, contrast, and sharpness, to optimize the image quality.
  • If using a video source, ensure appropriate video quality and compression settings.
  • Dull and washed-out image
  • Adjust the projector's brightness, contrast, and color settings to enhance the image.
  • Consider the ambient lighting conditions in the room. Dimming the lights or using a screen with better reflection properties can improve image vibrancy.

Warped or curved image

  • Check if the projector has keystone correction features. Use horizontal and vertical keystone adjustments to correct the image distortion due to uneven projection surfaces or angles.
  • Consider using a projector mount or stand that allows for precise alignment and adjustment.
  • Pixelated image
  • Ensure you set the input source to its native resolution or a resolution compatible with the projector. Higher resolutions generally yield sharper images.
  • If using a computer, adjust the display settings to match the projector's native resolution.
  • If the issue persists, the projector's resolution capabilities may be limited. In such cases, consider upgrading to a higher-resolution projector. 

Incorrect colors

  • Adjust the projector's color settings, including color temperature, saturation, and hue, to achieve accurate and pleasing outcomes.
  • Verify correctly configuring the input device's color settings and output format.
  • Use color calibration tools or professional calibration services to achieve accurate color reproduction. 

Image too bright or too dark

  • Adjust the projector's brightness and contrast settings to achieve the desired brightness level.
  • Consider the ambient lighting conditions and adjust room lighting accordingly.
  • If necessary, use neutral density filters or curtains to reduce excessive brightness.

Part of the image is cut off

  • Check the projector's aspect ratio settings. Ensure it matches the aspect ratio of the input source and the screen or surface you're using.
  • Adjust the projector's zoom and position to fit the image within the screen boundaries.
  • Use the projector's image shift or lens shift features to reposition the image if necessary.

Image looks like a trapezoid

  • Use the projector's keystone correction or digital keystone adjustment to correct the trapezoidal distortion due to the projector's position relative to the screen. 

Further Steps If Issues Persist

Sometimes, your ultra-short throw projector may fail to respond to the few twitches when rectifying issues. If that happens, please consult your manufacturer's tech support to comprehensively diagnose the underlying problem before fixing it.


Expert support can always be handy, and if you feel like making these little repairs isn't as easy as you imagined, you can contact support early on to restore your projector's functioning. These technicians can diagnose issues and fix them quickly. You can get these repairs at no charge if your warranty is valid.
