# Troubleshooting with PhotoRobot - User Support Manual Get quick and easy troubleshooting for all common issues with PhotoRobot installation, including cameras, robots, lights, editing and post-production. ## PhotoRobot Troubleshooting User Support Manual This PhotoRobot Troubleshooting User Manual describes solutions to common issues, including: hardware installation, cameras, robots, lights, editing and post production. **Note**: For more detailed information on the initial set up and configuration of PhotoRobot hardware and software, see the [Getting Started PhotoRobot User Manual](https://www.photorobot.com/manuals/getting-started). ## Cameras ### Controls App does not recognize my camera If CAPP does not recognize your camera, ensure that no other software connected to the camera is running on your computer. Typical examples of such software include the EOS Utility from Canon. Also check that the camera is connected via USB to the computer. Sometimes an issue can occur with the cable, so if necessary try replacing it with an alternate USB cable. ### LiveView is black In case LiveView displays only a black screen, check the **Exposure simulation** setting on your Canon camera and ensure that it is turned off. ## Robots ### Controls App does not recognize my robot If CAPP does not see your robot, always check in order that: 1. The robot is connected via ethernet to the local network. 2. The computer is on the same local network. 3. There is no firewall set up between the local network and the robot. 4. The robot is powered on. In some cases, it may simply be that the robot power is not on. ## Lights ### Lighting is inconsistent between frames with strobe lights When the lighting does not remain consistent between frames with strobe lights, try reducing the speed of the robot. It might be that the robot is performing the sequence too quickly and not providing enough time for the lighting to recharge itself. If this does not correct the issue, you can also try to reduce light intensity (in order for the lights to recharge quicker), or use more expensive lights. In general, Broncolor tends to charge faster than FOMEI. ## Editing ### I receive a blank screen when editing If experiencing a blank screen in edit mode, check that your computer has a graphic card with at least 2GB of memory. When using Windows, you might need to configure the Controls App to run in **Performance** mode. To do this, follow these steps: 1. Launch the Settings app. 2. Browse to System > Display > Graphics settings (find by scrolling down). 3. Browse for a classic app, select from the disk: **C:\Program Files\PhotoRobot Controls\PhotoRobot Controls**. 4. Set graphics preference to **High performance**.
