Power LEDs are not lit.

If a POWER LED is not lit, it indicates that your unit is not properly plugged in. It is important to check that all units within an installation are receiving power in order for your system to work correctly.

Nothing works or there is no video output

Is the green POWER LED lit? If it is not, check to make sure that the external AC power supply is plugged into both the Scan Do unit and the AC wall outlet.

Check to make sure that the computer is properly sending out aVGA or Mac signal by plugging the monitor directly into the computer's video output.

No video on outputs (just a color test pattern)

Is the green Input LED lit? If it is not, check that your computer is correctly connected to the Input connector on Scan Do Select. If it is connected properly, then your computer may not be producing a resolution within the valid range (see page 6) or may not be producing any signal at all.

Press the Test button to see if you get color bars on the composite and S-Video outputs. If you do get color bars, then the problem is related to your input signal. Check the items mentioned above. If you do not get color bars, the problem is related to your output. 

Is the VCR or video monitor in the proper mode to accept direct video input?

Is the output cable connected properly?

When using a laptop, try turning off the laptop’s LCD screen and having the VGA signal output through the external port only. 

Some of the image is being lost off the sides, top or bottom.

This is normal if you are in the overscan mode. See FAQs for information on the overscan/underscan function.

The color on the TV monitor is different than the color on the computer monitor. 

The colors on your TV monitor will never exactly match the colors on your computer monitor because each of these devices reproduce color differently. However, try adjusting the color, tint, contrast and brightness controls on your TV to help match the colors as best you can. 

All I see on the TV/monitor is "snow" when I connect Scan Do to it.

Since you are using a TV in its monitor mode, the TV is still set to show video from its tuner and not from the Video or S-video input.  Make sure the TV is switched to the “Video” or “Aux” input mode.  Refer to your TV user manual for instructions on how to do this.

Which is the "Video" input on the rear of my TV?

It is a phono jack, sometimes called an RCA jack.  It is smooth on the outside and usually yellow on the inside.  Do not connect Scan Do to the connector with the threads on the outside.  This where the antenna or cable TV drop is connected.

Why is the text of the Windows desktop almost unreadable on my video monitor? 

It requires a lot of bandwidth or resolution to reproduce all the detail that makes up small text.  TV monitors, by design, do not have the resolution to reproduce all the detail found in some computer screens.  That’s why they invented computer monitors.

How do I prevent the color "bleeding" on my monitor?

If possible, avoid using color on color combinations.  Try to use white, black, and shades of gray whenever possible.

How do I connect my Scan Do to an ordinary TV set? 

There are two ways.  In North America, you can use our Model 1009 RF modulator kit which will take the video output of Scan Do and turn it into TV channel 3 or 4.  You can also connect the video output of Scan Do to the video input of a VCR and use its RF output to feed your TV set.

No video on the output of Scan Do® Select, just a color test pattern.

Scan Do Select automatically generates a color bar pattern on its output when there is no computer video input present.  It will also generate the pattern if the computer video input that is present has a horizontal sync frequency greater than 71 kHz.

How do I see the entire computer image on the output of Scan Do® Select?

Press the ZOOM button on the front panel until the image shrinks to 85% of its normal size.  You may also have to position the image, using the arrow buttons, to properly center the image.

My PC video has a 3 wire interface (sync-on-green.) Will Scan Do® Select support this?

Scan Do Select and Scan Do Ultra automatically detect and use sync-on-green computer inputs as long as the input does not exceed the maximum rated horizontal sync frequency for the scan converter.

I want to rack mount my Scan Do® Select. How do I do that?

We offer two rack mount kits.  Model 1240 will rack mount one Scan Do Select and Model 1241 will rack mount two units side by side.

Why should I use Scan Do® Pro instead of Scan Do® Select?

Scan Do Pro has three important features compared to Scan Do Select.  First, it is genlockable.  That is, the video output of Scan Do Pro can be genlocked or synchronized to video reference.  Second, an RGB output is standard on Scan Do Pro.  Finally, Scan Do Pro can be expanded with component video and SMPTE 259 SDI outputs and RS-232 remote control.  These expansion options can be added at time of ordering or in the field on a unit you may now be using.

Can Scan Do® Pro be timed into my production switcher?

Yes.  The front panel GENLOCK PHASING button allows the front panel arrow keys to be used to adjust horizontal timing and subcarrier phasing.

What does Scan Do® Ultra offer that is different from other Scan Do® models?

Scan Do® Ultra is designed to scan convert as many different computers and computer resolutions as possible.  It also offers the user maximum flexibility in the conversion process.  Features exclusive to Scan Do Ultra include variable image sizing from 50% to 100%, variable flicker reduction, five non-volatile presets for sizing, positioning and imaging processing, and image processing to adjust brightness, contrast, saturation, and hue of the scan converted image.
