ITEMS TO CHECK

LOCATION

Thin vertical black lines on one or both sides of the screen. This minor condition is caused by grille element overlap which can occur during shipping.

Position an open white window over the affected area of the screen and maximize the brightness and contrast controls. This will cause localized heating of the overlap which will clear in a few minutes. Be sure to readjust the brightness and contrast controls back to the normal viewing levels after this procedure.

•The 2 very faint thin lines across the screen are normal. They are caused by the aperture grille stabilization filaments(Damper Wires) which are required for all aperture grille CRTs’.

•A brief vibration or hum sound that is heard just after power up is normal. This is caused by the automatic degaussing function. This sound will be heard each time the monitor is powered up from a cold start and each time the manual degauss button is used.

•Check the color bar. (e.g RED, GREEN, BLUE)

•CHECK the H, V signal input.

•Push the > button, the picture size is expanded to a large size.

•Check power-on indicator on the bezel.

If this indicator is blinking (Orange--> Black--> Orange), there is a possibility of failer.
