Troubleshooting
What should I do if I cannot play a disc properly on my computer?
❑ Make sure the disc is inserted into the optical disc drive with the label facing upward.
❑ Make sure the necessary program(s) is installed according to the manufacturer's instructions.
❑ Blu-ray Disc playback on a connected external display may be interrupted, depending on the type or bit rate of the video.
You may be able to solve this problem by lowering the screen resolution of the display. Follow the steps in Why doesn't
my screen display a video? (page 206) to change the screen resolution.
❑ If a disc is dirty or damaged, your computer will stop responding. Follow these steps:
1 Press the Ctrl+Alt+Delete keys and click the arrow next to the Shut down button and Restart to restart the computer.
2 Remove the disc from the optical disc drive.
3 Check the disc for dirt or damage. If you need to clean the disc, see Handling Discs (page 167) for instructions.
❑ If you are playing a disc and cannot hear sound, do any of the following:
❑ The volume may have been turned off by the muting button. Press the button once again.
❑ The volume may have been minimized by the volume down button. Press the volume up button several times or keep
pressing the button to turn up the volume loud enough to hear sound.
❑ Right-click the volume icon on the taskbar and click Open Volume Mixer to check the settings.
❑ Check the volume setting in the audio mixer.
❑ If you are using external speakers, check the volume settings on the speakers and the connections between the
speakers and your computer.
❑ Make sure the correct driver software is installed. Follow these steps:
1 Click Start and Control Panel.
2 Click System and Maintenance.
3 Click System.
