Troubleshooting

♦What do I do if no LEDs light when I plug the power supply?

The iScan Pro should automatically come “on” when plugged in. Check the connections to the iScan Pro, and to the power source. If all of these look good, you may have a failed power supply or a failed unit.

♦What do I do if the power is on but I get no picture on the screen?

The basic troubleshooting procedure is:

1)Check the Power indicator. If it’s not lit, you may have a bad power supply.

2)If the Power indicator is lit, check the Input indicators. Does the iScan Pro indicate that the input is active?

3)If so, try plugging that same input cable directly into your display to see if that works.

4)If it’s OK, plug it back into the iScan Pro and make sure that, again, the input indicator switches to that input.

5)In order to test the output, we generally recommend hooking up the iScan Pro to any inexpensive computer monitor using a standard VGA-to-VGA computer monitor cable. Make sure that you use a different cable than the one that you are using for your display. Also make sure that the “Colorspace” switch on the front of the iScan Pro is set to the RGB position. Since all but the most ancient computer monitors are capable of displaying a VGA type signal, and since the iScan Pro generates nearly an identical signal, this should allow you to reliably check the output of the iScan Pro.

6)If the computer monitor displays the video OK, then the problem is either in the original video output cable, it’s connection to the display, the colorspace setting or in the display itself.

7)Try a different output cable with your display to see if that’s the problem.

8)Try flipping the colorspace switch back and forth to see if that helps.

9)If neither of these helps, verify once again that your display is capable of accepting a 31.5 KHz input. Beyond this, you may wish to contact the dealer where you bought the iScan Pro and/or the display.

10)If the computer monitor doesn’t show the video output and a different cable was used then it sounds like there might be something wrong with the iScan Pro. In these cases, you should contact your dealer for service.

♦What do I do if the power is on and I get a stable image but my colors are incorrect?

-Using a DVD or VCR in pause mode do the following:

-Flip the color space switch on the back panel of the iScan Pro to see if that fixes it.

-If not, try wiggling the output cable at the iScan Pro and at the display to see if it has any effect.

-If you are using an RGB device with BNC, try removing all three color signals (Red, Green, Blue) and reinserting them one at a time. First insert the Red wire into the Red input connector and see if the image appears but is red.

-Then remove the Red signal and insert the Blue signal into the Blue connector and verify that the picture is blue.

-Then repeat with only the Green.

-If all three of these work, then plug them all back in again.

-Still no luck? It may be that the colors on the cable are mislabeled. Using a source with colors that you are familiar with, try to determine if two of the colors are swapped.

-If you are not using RGB but are using YPbPr inputs, then try removing the Pr and Pb (red and blue) connectors from your display. This should result in a black and white picture.

Progressive Scan Display Interface specifications

DVDO Progressive Scan Display Interface (PDI) is an advanced technology designed to enhance video quality and user experience in display systems. It serves as a bridge between source devices, like DVD players or gaming consoles, and output displays such as televisions and projectors. The main purpose of the PDI is to provide a better visual experience by minimizing motion artifacts, enhancing color accuracy, and improving overall image clarity.

One of the key features of DVDO PDI technology is its progressive scan capability. Unlike traditional interlaced scanning methods where alternate lines of an image are displayed in each frame, progressive scanning delivers the entire image at once. This results in smoother motion and sharper images, especially beneficial for fast-paced content like sports or action movies.

Another important characteristic of DVDO PDI is its upscaling ability. The interface can take lower resolution video sources and convert them into higher quality outputs, ensuring that older video content can still look impressive on today’s high-definition displays. This upscaling feature is critical for users who still want to enjoy classic films or legacy video games without compromising on picture quality.

The technology also incorporates sophisticated deinterlacing algorithms that intelligently analyze video signals. These algorithms help in reducing visual artifacts such as combing and blurring, commonly found in interlaced video formats. This enhancement is particularly useful for mixed video sources, allowing seamless switching between different content types without noticeable degradation in quality.

DVDO PDI is also designed with various connectivity options to ensure compatibility with a wide range of devices. High-definition multimedia interface (HDMI) compatibility allows for easy integration with modern displays, while additional outputs can cater to older systems, making it a versatile choice for multimedia setups.

Moreover, the user-friendly features of DVDO PDI include adjustable settings for color calibration, contrast enhancement, and image scaling, allowing users to customize their viewing experience. This adaptability makes it suitable for both home theater enthusiasts and casual viewers alike.

In conclusion, the DVDO Progressive Scan Display Interface stands out with its combination of progressive scanning, upscaling, intelligent deinterlacing, and extensive connectivity options. These characteristics work together to deliver an enhanced viewing experience, ensuring that users enjoy superior video quality regardless of the source material. As technology continues to evolve, DVDO remains at the forefront of display innovations, offering solutions that cater to the diverse needs of consumers.
