• Cancel the AV mute by pressing the MUTE button.

 

 

 

• Remove the lens cap.

 

 

 

 

• The lamp sometimes takes about one minute to light up.

 

• On rare occasion, the lamp fails to light up. In such cases, wait a few minutes and try to light the lamp again.

Images aren’t projected on the screen.

• If the projector was turned off before the lamp cooled down completely, the fans may start rotating and the

 

POWER button may not function when you plug the power cord into the wall outlet next time. Wait for the fans

 

 

 

 

to stop and press the POWER button to turn on the lamp again.

 

• Check that the cable connected to the external device isn’t broken.

 

• When an extension cord is being used, replace it with the supplied cable and check whether images are pro-

 

 

jected correctly. If images are projected correctly, use an RGB signal amplifier along with the extension cord.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

• This condition may occur when an inlet or an outlet is blocked.

 

 

(If this is the case, the STATUS indicator lights red.)

 

 

 

 

J

Remove the object which blocks the inlet or outlet, and then perform the following operations.

 

 

 

 

 

1. Wait until the air inlet/outlet fan stops (until the STATUS indicator turns off.)

 

 

 

 

 

2. Disconnect the power plug from the power outlet.

 

 

 

 

 

3. Wait 10 minutes or longer.

 

 

The power is turned off.

 

 

 

 

4. Connect the power plug to the power outlet.

 

 

 

 

 

 

 

5. Press the power button.

 

 

 

• If the STATUS indicator illuminates in red, it indicates the lamp should be exchanged. Exchange the light

 

 

source lamp.

 

 

 

 

• Check whether or not the “Auto power off” function is set.

 

• Check whether or not the lifetime indicator of the lamp illuminates.

 

• A degraded lamp may illuminate, and go out after a while.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

• The air inlet or outlet grille may be blocked. (In such cases, the STATUS indicator lights red.)

 

 

J

Remove the objects blocking the air inlet or outlet grille and carry out the following.

 

 

 

 

 

1. Wait for the air inlet or outlet fan to stop (or wait for the STATUS indicator to go out.)

 

 

 

 

 

2. Unplug the power cord from the wall outlet.

 

 

Images suddenly disappear.

 

 

 

 

3. Wait about 10 minutes.

 

 

 

 

 

 

 

4. Plug the power cord into the wall outlet.

 

 

 

 

 

 

 

5. Press the POWER button.

 

 

 

• When the STATUS indicator is blinking red, it is indicating that the lamp should be replaced. Replace the lamp

 

 

in this case.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

• Turn on the power of the connected device, or check whether there is something wrong with the connected

 

 

device.

 

 

 

 

 

 

 

 

 

 

• Check whether the external device outputs signals. (Check this especially when the external device is a note-

 

 

book computer.)

 

 

 

"NO SIGNAL" is displayed.

• Check that the cable connected to the external device isn’t defective.

 

• Check that the projector is connected to the external device using the correct terminals.

 

• Check that the connected device is correctly selected as the input source.

 

• When an extension cord is being used, replace it with the supplied cable and check whether images are pro-

 

 

jected correctly. If images are projected correctly, use an RGB signal amplifier along with the extension cord.

SD105U specifications

The Mitsubishi Electronics SD105U is a cutting-edge projector designed to cater to a variety of presentations and display needs, blending portability with advanced features that enhance user experience. This model stands out in several areas, such as brightness output, resolution, and connectivity options, making it suitable for business, educational institutions, and even home use.

At the heart of the SD105U is its high brightness output of 3,000 ANSI lumens, which ensures that presentations remain vivid and clear even in well-lit rooms. This feature is critical for auditoriums or conference rooms where ambient light can often wash out visuals. Coupled with a contrast ratio of 2,000:1, the projector produces deep blacks and vibrant colors, contributing to sharp images and detailed presentations.

The SD105U supports a native resolution of XGA (1024x768), making it ideal for displaying high-quality images, graphics, and text. This resolution is well-suited for PowerPoint presentations and academic lectures, providing clarity that captures and retains audience attention. Additionally, the projector features a range of aspect ratios, including 16:9 for widescreen displays, allowing for versatility depending on the content being projected.

One of the key technologies incorporated into the SD105U is the 3LCD system, which employs three separate LCD panels for red, green, and blue light. This design not only enhances color reproduction but also minimizes the risk of color breakup, leading to smoother and more realistic visuals. As a result, users can expect impressive color accuracy and lifelike images.

In terms of connectivity, the SD105U is equipped with multiple input options, including HDMI, VGA, and USB ports. This range of connectivity allows for seamless integration with various devices, whether it's laptops, media players, or even smartphones, ensuring that users can easily share their content. Additionally, the projector supports digital and analog signals, enhancing its compatibility with older equipment.

The SD105U is also designed with user convenience in mind. Features like a lightweight chassis and robust carry handle make it portable, perfect for professionals on the go. It also includes a quick-start option, allowing users to power up the device rapidly and get started without delays, crucial for time-sensitive presentations.

Moreover, its lamp life spans up to 5,000 hours in economy mode, reducing the need for frequent replacements and lowering overall maintenance costs. This longevity is a significant benefit for institutions and businesses looking to minimize downtime and expenses.

In summary, the Mitsubishi Electronics SD105U is a versatile projector that combines high brightness, excellent image quality, and practicality, making it an ideal solution for various applications. Whether used in business, education, or entertainment, its advanced technologies and features ensure that users can deliver impactful presentations that leave a lasting impression.
