<v ->In this section of the course,</v>



2

00:00:01.770 --> 00:00:04.320

we're going to talk all about how to troubleshoot video issues



3

00:00:04.320 --> 00:00:05.370

on a given system,



4

00:00:05.370 --> 00:00:07.890

including physical cabling and source selection,



5

00:00:07.890 --> 00:00:10.560

projector issues, and video quality issues.



6

00:00:10.560 --> 00:00:12.480

So as we move into this section,



7

00:00:12.480 --> 00:00:14.820

we're again going to be focused on domain five,



8

00:00:14.820 --> 00:00:16.710

hardware and network troubleshooting,



9

00:00:16.710 --> 00:00:19.260

as we fully cover objective 5.4.



10

00:00:19.260 --> 00:00:22.200

Objective 5.4 states that given a scenario,



11

00:00:22.200 --> 00:00:23.580

you must be able to troubleshoot



12

00:00:23.580 --> 00:00:26.130

video projector and display issues.



13

00:00:26.130 --> 00:00:27.660

Now as we begin this section,



14

00:00:27.660 --> 00:00:29.880

we're first going to take a look at different cabling and



15

00:00:29.880 --> 00:00:31.860

source selection issues that can occur,



16

00:00:31.860 --> 00:00:34.980

including selecting the wrong data source, broken cables,



17

00:00:34.980 --> 00:00:37.710

and cables that aren't properly seated into the connectors



18

00:00:37.710 --> 00:00:39.000

and much more.



19

00:00:39.000 --> 00:00:41.400

Then we're going to move into some different projector issues



20

00:00:41.400 --> 00:00:43.440

that you might encounter as a technician,



21

00:00:43.440 --> 00:00:46.620

such as when a projector has a burned out bulb, a dim image,



22

00:00:46.620 --> 00:00:49.050

or intermittently shuts itself down.



23

00:00:49.050 --> 00:00:50.970

After that, we'll move into our discussion



24

00:00:50.970 --> 00:00:52.440

of video quality issues,



25

00:00:52.440 --> 00:00:55.050

including fuzzy images, display burn ins,



26

00:00:55.050 --> 00:00:57.030

dead pixels, flashing screens,



27

00:00:57.030 --> 00:00:59.970

and incorrect colors being shown on your display.



28

00:00:59.970 --> 00:01:01.920

As you're going to learn in this section of the course,



29

00:01:01.920 --> 00:01:03.870

there are lots of different video issues



30

00:01:03.870 --> 00:01:06.300

that you are going to encounter as a technician in the field,



31

00:01:06.300 --> 00:01:08.910

and you're going to be asked to troubleshoot and rectify them.



32

00:01:08.910 --> 00:01:10.980

So let's get started with our coverage



33

00:01:10.980 --> 00:01:12.600

of how to troubleshoot video issues



34

00:01:12.600 --> 00:01:14.100

in this section of the course.
