Troubleshooting

terminology associated with personal computers and with the safety practices and regulatory compliance required for using and modifying electronic equipment.

❑Disconnect the system from its power source and from any telecommunications links, networks, or modems before you open the system or follow any of the procedures described in the online manual, Upgrading and Maintaining Your VAIO Digital Studio Computer. Failure to do so may result in personal injury or equipment damage.

❑Electrostatic discharge (ESD) can damage disk drives, add-on cards, and other components. Follow the procedures described in the online manual, Upgrading and Maintaining Your VAIO Digital Studio Computer, only at an ESD workstation. If such a station is not available, do not work in a carpeted area, and do not handle materials that produce or hold static electricity (for example, cellophane wrappers). Ground yourself by maintaining continuous contact with an unpainted metal portion of the chassis while performing the procedure.

❑When removing a slot cover, be careful not to damage components on the system board or add-on cards. You may need to temporarily remove add-on cards that are next to the slot cover you want to remove.

Handling a CRT display

❑Do not change the CRT display refresh rate to 85 Hz, as DVD playback and the DVgate software may not function correctly. Sony suggests that you keep your CRT display at the preset, optimal refresh rate (75 Hz).

❑Do not place the display near a strong magnetic force.

❑Do not block the ventilation slots on the display.

❑Using the computer in low temperature conditions may produce a residual image on the screen. This is not a malfunction. When the computer returns to normal temperature, the screen returns to normal.

❑A residual image may appear on the screen if the same image is displayed for a lengthy period of time. The image disappears after a period of time. You can use a screen saver to prevent residual images.

❑The screen becomes warm during operation. This is normal and does not indicate a malfunction.
