Diagnostics and Repair - Video

Video problems are widely variable. It could be a faulty cable, signal problem, video noise, improper camera setting for the conditions, or even lighting.

If there is no video signal, first verify that rest of the system is functional. If the rest of the system is functional, verify that the video circuit in the control panel is recognized by the computer. The video circuit can be verified by checking the Sound, video and game controllers section in Device Manager. To access device manager, open the Windows Control Panel, and in the Classic View, click on System. Next, click on the Hardware tab, and then the Device Manager button. Click on the plus sign (+) next to Sound, video and game controllers and confirm that the DVD Maker 2 device is listed. If the DVD Maker 2 device is not listed, unplug the USB cable, wait a few seconds and plug it back in. If the DVD Maker 2 is still not listed, power down the control panel and reboot the computer. If the DVD Maker 2 is not listed after a shut down, restart and reboot, a problem with the USB cable, DVD Maker 2 device, or internal USB hub or controller is possible.

If video noise seems to be a problem, it could be local interference, a mismatched ground, or a poor connection somewhere in the system. If you are operating off a local power source such as a generator, make sure the ground is the same as the water in which the ROV is being used. Also, check that each connection in the tether is clean and well seated.

If you do not have video on the second monitor, make sure the monitor is powered on, the cable connected and computer configured to display on two screens.

If the video image is poor, check the camera focus and the camera settings. You may also need to adjust the lights.
