What to do if Mitsubishi Electric Projector images are distorted?
To resolve distorted projected images on your Mitsubishi Electric Projector, adjust the projector and the screen so that they are perpendicular to each other.
How to fix blurred images on Mitsubishi Electric DLP UD740U?
If the projected images from your Mitsubishi Electric Projector are blurred, try the following: Adjust the focus, clean the lens, and press the ? or ? button on the remote control to eliminate flicker. Also, adjust Tracking and Fine sync in the Signal menu. Set Overscan in the Signal menu to 100% and the keystone adjustment value to 0 using the KEYSTONE button. Adjust Brightness and Contrast in the Picture menu. Ensure the projector and screen are perpendicular.
Why are Mitsubishi Electric DLP UD740U Projector images dark?
If the projected images from your Mitsubishi Electric Projector are dark, adjust the Brightness and Contrast settings in the Picture menu. Note that 3D images may appear darker, which is normal. When viewing 2D images, set the 3D setting in the Picture menu to Auto (for HDMI input only) or Off. If the issue persists, consider replacing the lamp.
Why are Mitsubishi Electric Projector images shaking?
If the projected images from your Mitsubishi Electric Projector are shaking or displaced, check that the cable connected to the external device is not intermittent and connect the cable's plug firmly. For image correction, project an image with many characters and without black areas, then press the AUTO POSITION button. If issues persist, adjust the Signal Detect setting in the Option menu and press the AUTO POSITION button again. If the position and size are still incorrect, use the Signal menu for adjustments.
Why does my Mitsubishi Electric DLP UD740U say no signal?
If you are seeing a 'No signal' message on your Mitsubishi Electric Projector, first ensure the connected device is powered on and functioning correctly. Verify that the external device is outputting signals. Check the cable connecting the projector to the external device for any defects and ensure it's connected to the correct terminals. Confirm that the connected device is correctly selected as the input source. If using an extension cord, try replacing it with the supplied cable, and if that works, use an RGB signal amplifier with the extension cord.
Why does my Mitsubishi Electric DLP UD740U Projector power turns off?
If your Mitsubishi Electric Projector turns off unexpectedly, remove any objects blocking the intake and/or exhaust vents. Wait for the fans to stop and the STATUS indicator to go out, then unplug the power cord, wait 10 minutes, plug it back in, and press the POWER button. If the STATUS indicator is steady red, replace the lamp. Ensure that the Auto Power Off setting is disabled. The lamp may also go out if it has deteriorated.
Why Mitsubishi Electric DLP UD740U power can not be turned on?
If your Mitsubishi Electric Projector's power cannot be turned on, ensure the power cord is correctly connected to both the projector and a working wall outlet. If there are any obstructions blocking the intake or exhaust vents, remove them. Then, unplug the power cord, allow the projector to cool, plug the cord back in, and press the POWER button. Avoid exposing the exhaust vents to heat from other appliances. If the indicator light is steady red, replace the lamp, as it has likely reached the end of its life. Make sure the lamp cover is securely attached. If the issue persists, unplug the power cord and contact your dealer.
