Troubleshooting
Before contacting technical support, refer to this section.

RESET
When the monitor receives an input signal, it automatically matches the signal to one of the factory preset modes stored in the monitor�s memory to provide a high quality picture at the center of the screen. (See Appendix for a list of the factory preset modes.) For input signals that do not match one of the factory preset modes, the digital Multiscan technology of this monitor ensures that a clear picture appears on the screen for any timing in the monitor�s frequency range (horizontal: 30 � 70 kHz, vertical: 48 � 120 Hz). If the picture is adjusted, the adjustment data is stored as a user mode and automatically recalled whenever the same input signal is received.

1 Press the center of the control button.
The main MENU appears on the screen.

If thin line appears on your screen (damper wire)
The line you are experiencing on your screen is normal for the Trinitron monitor and is not a malfunction. This is shadow from the damper wire used to stabilize the aperture grill and is most noticeable when the screen�s background is lightly (usually white). The aperture grille is the essential element that makes a Trinitron picture tube unique by allowing more light to reach the screen, resulting in a brighter, more detailed picture.
