Why remote control doesn't function easily with Mitsubishi Electric Projector?
If the remote control isn’t functioning easily or at all with your Mitsubishi Electric Projector, check that the batteries are loaded correctly and are not weak. Also, ensure that the remote control sensor isn’t exposed to direct sunlight or fluorescent light. Use the remote control within its operation range and at least 10 cm away from the projector.
What to do if no image appears on Mitsubishi Electric DLP HC7800D Projector?
If no image is appearing on your Mitsubishi Electric Projector, start by ensuring the lens cap is removed. It may take about one minute for the lamp to light up. If the lamp doesn't light up, wait a few minutes and try again. If the projector was turned off before the lamp cooled down sufficiently, the fan may start rotating and the power button may not work. Wait for the fan to stop, then press the power button. Ensure the intake vent is clean and the lamp cover is closed. Check that the cables connected to external devices are not broken. If using an extension cable, replace it with the supplied cable for testing. Finally, consult the operation manual of the video device for its connection.
Why are my Mitsubishi Electric DLP HC7800D images dark?
If the projected images from your Mitsubishi Electric Projector appear dark, you can adjust the brightness and contrast settings in the IMAGE menu. If adjusting these settings doesn't resolve the issue, the lamp may need to be replaced.
How to fix blurry images on Mitsubishi Electric Projector?
To fix blurred images on your Mitsubishi Electric Projector, start by adjusting the focus. If the issue persists, try cleaning the lens. You can also press the specified buttons on the remote control to eliminate flicker. Adjust the TRACKING and FINE SYNC in the SIGNAL menu, as well as the BRIGHTNESS and CONTRAST in the IMAGE menu. Finally, ensure the projector and screen are perpendicular to each other.
What to do if Mitsubishi Electric DLP HC7800D images are shaking?
If the projected images from your Mitsubishi Electric Projector are shaking or displaced, check that the cable connected to the external device isn’t intermittent and ensure the cable’s plug is firmly connected to the external device’s connector. You can also try pressing the AUTO POSITION button. In rare cases, some computers output out-of-spec signals, so you may need to adjust the SIGNAL menu.
Why is my Mitsubishi Electric Projector image freezing?
When an image from a VCR is projected on your Mitsubishi Electric Projector, it may remain freezing during speed search. This is not a malfunction.
Why does Mitsubishi Electric DLP HC7800D Projector only display motion areas?
If only the motion areas in the images supplied from the computer aren’t displayed on your Mitsubishi Electric Projector, this issue is caused by the computer being used. Contact the manufacturer of your computer for assistance.
Why are my Mitsubishi Electric Projector images obscured?
If the projected images from your Mitsubishi Electric Projector are obscured, match the output resolution of your computer with the resolution of the projector. Contact the manufacturer of your computer for instructions on how to change the output resolution.
Why are my Mitsubishi Electric Projector images wavy?
If the projected images from your Mitsubishi Electric Projector appear wavy, ensure that the plugs of the cables are securely connected to external devices. Additionally, keep the projector away from devices that emit interfering radio waves.
Why does Mitsubishi Electric Projector show white or black dots?
The appearance of white or black dots on projected images from a Mitsubishi Electric Projector is normal for a DLP™ projector and is not a malfunction. A very small number of pixels may stay lit or out, but this is not a malfunction, especially if 99.99% or more are effective.
