TROUBLESHOOTING   

If the recommended actions still do not result in satisfactory operation, please consult your Kramer Dealer.  
Before seeking technical assistance, if the problem is image related, please try to find out the screen resolution 
and refresh rate being used from the computer and if the problem only affects one particular resolution. 

 

Problem Remedy 

 

 The picture on the video 
display is black and 
white. 

1.  If you are using the S-Video or Composite outputs, then make 

sure that all these cables are connected correctly.   

2.  Make sure that the Scan Converter is adjusted to the right video 

standard PAL/NTSC (The procedure to change this is found 
elsewhere in this manual).  

3.  Ensure that the color controls on your TV or video monitor are all 

set correctly. 

There is no picture on 
the video monitor. 

1.  If you're using the unit with a laptop computer, make sure the 

laptop is set to enable an external display device.  Some laptops 
automatically detect external video connections, but others will 
need setting up to do so.  This is often accomplished by pressing 
two keys simultaneously on the keyboard. 

2.  If the Power LED on the Scan Converter is off, ensure that the 

proper AC Power is being supplied to the unit and check the fuse 
(The procedure located elsewhere in this manual). 

3.  If the Power LED is on: a) Check that the monitor output from the 

computer is connected to the Scan Converter’s VGA IN 
connector, b) Check that the output you are using from the Scan 
Converter is also connected at the unit and the video monitor, and 
c) Check that your video monitor is switched on and set to the 
correct input (AUX or A/V is selected), also make sure that the 
Brightness and Contrast on the video monitor are set correctly. 

4.  Don’t forget that when the Scan Converter is in the YUV Mode, 

all other video outputs will be blanked out. 

There is no picture on 
the computer monitor. 

1.  Check that the VGA output from the computer is connected to the 

Scan Converter’s VGA IN connector.   

2.  Check that the computer monitor is connected to the VGA OUT 

connector on the back of the Scan Converter.  

3.  Check that your computer monitor is turned on and the Brightness 

and Contrast are set correctly. 

The display on the TV 
has a huge border around 
it. 

1.  This usually means that you are using a laptop computer at a 

resolution lower than the laptop's own screen.   When this 
happens, the laptop fits the smaller resolution into the larger with 
a border around the edge.   

2.  Since the laptop's screen is of a fixed resolution, the only two 

solutions are: a) change the resolution you're running at to match 
the laptop's own internal screen, or b) disable the laptop's own 
screen, so you just see the image on the video monitor. 

The unit does not 
respond to the Infrared 
remote control. 

1.  Ensure that there are batteries in the Remote Control unit are 

correctly inserted and that they have enough charge left.   

2.  Make sure that there is no obstruction in front of the Scan 

Converter's Front Panel Infrared Window.   

3.  Ensure that the Scan Converter is set for control from the IR unit 

(The procedure to change this is found elsewhere in this manual). 

There is excessive 
flicker on the TV. 

1.  Try using a different Flicker Reduction Filter setting (The 

procedure to change this is found elsewhere in this manual).   

2.  Turning the contrast down and the brightness up on the video 

monitor can also have a large effect on flicker.
