Why does my Mitsubishi Electric Projector have color unevenness?
Color unevenness in images from your Mitsubishi Electric Projector is due to the projector utilizing a high-definition DLP™ chip, which can cause color variations (at the center of the screen and along the rims of the active area) due to diffraction of light. This is not a malfunction.
Why is my Mitsubishi Electric Projector showing different color tint?
When comparing images projected by two projectors, different tints may appear because of variation between their optical components. This is not a malfunction. Also, when comparing the image projected by this projector with those displayed on a television or PC monitor, differences in tints may occur because of differences in the range of color reproducibility, which is also not a malfunction.
Why is tint incorrect on my Mitsubishi Electric Projector?
If the tint in projected images from your Mitsubishi Electric Projector is incorrect, ensure that COMPUTER INPUT in the SIGNAL menu is correctly set. Also, check that the cable connected to the external device isn’t broken.
Why does my Mitsubishi Electric DLP HC7800D say 'NO SIGNAL'?
If your Mitsubishi Electric Projector displays 'NO SIGNAL', several factors could be the cause. Ensure the connected device is powered on and functioning correctly. Verify that the external device is outputting signals, especially if it's a notebook computer. Check the cable connecting the devices for any defects and confirm that you're using the correct terminals for the connection. Also, ensure the connected device is correctly selected as the input source. If you're using an extension cord, try replacing it with the supplied cable to see if that resolves the issue; if it does, consider using an RGB signal amplifier with the extension cord.
Why does my Mitsubishi Electric Projector have fine streaks?
Fine streaks on projected images from your Mitsubishi Electric Projector are often due to interference with the screen surface and are not a malfunction. Try replacing the screen or slightly displacing the focus. Vertical or horizontal streak noise may also appear depending on the DVD player or game console used; in such cases, you can reduce the noise by enabling the LPF.
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 my Mitsubishi Electric Projector have rainbow effect?
The rainbow effect seen on projected images from your Mitsubishi Electric Projector is due to color breaking noise that occurs in a DLP™ system and is not a malfunction.
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.
Why are my Mitsubishi Electric DLP HC7800D Projector images jagged with HDMI?
If images appear jagged or “NO SIGNAL” is displayed when connecting your Mitsubishi Electric Projector using an HDMI cable, ensure the cable is firmly plugged into the connecting terminal. To accept and display 1080p signals, use a high-speed HDMI cable. If using a distributor or AV amplifier, verify it complies with HDMI1.3 or higher (Deep Color) for standard display, or HDMI1.4 or higher (3D display) when displaying 3D images.
Why are projected images from Mitsubishi Electric DLP HC7800D flickering?
Projected images from the Mitsubishi Electric Projector may flicker after the power button or the ON button on the remote has been pressed, or after the Lamp mode setting has changed, until the lamp lights stably. This is an expected behavior. Also, when selecting the input signal and Auto Position, the projected image may flicker temporarily, and this is not a product malfunction.
