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

 
The iScan Plus v2 should automatically come “on” when plugged in. Check the 
connections to the iScan Plus v2, and to the power source. If all of these look good, you 
may have a failed power supply.  

 

♦ 

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 Plus v2 

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 Plus v2 and make sure that, again, the input 

indicator switches to that input. 

5)  If it’s an S-Video signal, try using the other S-Video input on the iScan Plus v2. 
6)  In order to test the output, we generally recommend hooking up the iScan Plus v2 to 

any inexpensive computer monitor using a standard VGA

Æ

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 back of the iScan 
Plus v2 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 Plus v2 generates 
nearly an identical signal, this should allow you to reliably check the output of the 
iScan Plus v2. 

7)  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. 

8)  Try a different output cable with your display to see if that’s the problem. 
9)  Try flipping the colorspace switch back and forth to see if that helps. 
10)  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 Plus v2 and/or the display. 

11)  Are one or all three of the Processing Mode indicators lit? If none of them are lit but 

the Input indicators show a stable active source, then there is something wrong with 
the iScan Plus v2. 

12)  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 Plus v2. In 
these cases, you should talk to your dealer or distributor and ask for a replacement 
iScan Plus v2.

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

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

Flip the color space switch on the back panel of the iScan Plus v2 to see if that fixes it. 

If not, try wiggling the output cable at the iScan Plus v2 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.
