Power
When the HD Entertainment Center is turned on, nothing happens:
• If the HD Entertainment Center is plugged into a surge protector or UPS, make
sure that the surge protector or UPS is securely connected to an electrical
outlet, is switched on and working correctly.
• Check that the wall outlet is working properly by testing another device such
as a radio or lamp that you know works. If the wall outlet is not working,
please contact an electrician or your power company for further assistance.
• Check that all devices on the HD Entertainment Center are properly connected
to your HD Entertainment Center and that the HD Entertainment Center is
properly connected to the surge protector or UPS.
Speakers
There is no sound from the speakers (external):
• Check that you selected the appropriate speaker connection type in Vista
Media Center (refer to page 34)
• Check the cables of the speakers and make sure they are properly connected
to the appropriate jacks on the back of the HD Entertainment Center.
• Check that the speakers are on and receiving power.
• Check that the volume settings in Windows are turned on and adjusted to a
medium level setting. Make sure that all mute controls are off.
• If possible, test another set of speakers on your HD Entertainment Center to
ensure that the audio is working.
• For further troubleshooting, refer to the speaker User Manual.
Game Controllers
The HD Entertainment Center does not recognize the game controller:
• Check that the cable connecting the game controller to the HD Entertainment
Center is not damaged and that it is properly connected.
• Reinstall the device driver for the game controller.
