CHAPTER 5: Troubleshooting

5. Troubleshooting

If the monitors or other output devices don’t seem to be displaying or recording
the image from the video source, first check to make sure that the video source
device is ON and that it’s properly connected to the Video Splitter-8. Then make
sure that the output devices are properly connected to the Splitter-8.

If this doesn’t help, or if you have some other problem, contact Black Box as

described in the rest of this chapter.

5.1 Calling Black Box

If you determine that your Video Splitter-8 is malfunctioning, 

do not attempt to alter

or repair it

. It contains no user-serviceable parts. Contact Black Box Technical

Support at 724-746-5500.

Before you do, make a record of the history of the problem. We will be able to

provide more efficient and accurate assistance if you have a complete description,
including:

• the nature and duration of the problem;

• when the problem occurs;

• the components involved in the problem—that is, what type of input device,

what type of output device, type and make of your cables, etc.;

• any particular application that, when used, appears to create the problem or

make it worse; and

• the results of any testing you’ve already done.

5.2 Shipping and Packaging

If you need to transport or ship your Video Splitter-8:

• Package it carefully. We recommend that you use the original container.

• If you are shipping the unit for repair, please include its power supply. If you

are returning the unit, please include everything you received with it. Before
you ship it back to Black Box for repair or return, contact us to get a Return
Authorization (RA) number.
