Sony Trinitron CPD-420GS - POWER SAVING FUNCTION; SELF DIAGNOSIS FUNCTION; TIMING SPECIFICATION

CPD-420GS/GST
—2—
The monitor has three Power Saving modes. By sensing the
absence of a video signal from the computer, it reduces power
consumption as follows:
NOTE: If no video signal is input to the monitor, the “NO
INPUT SIGNAL” message appears. After about 30
seconds, the Power Saving function automatically puts
the monitor into active-off mode and the indicator
lights up orange. Once the monitor detects horizontal
and vertical sync signals, the monitor automatically
resumes normal operation mode.
SELF DIAGNOSIS FUNCTION
When a failure occurs, the STANDBY/TIMER lamp will flash a set number of times to indicate the possible cause of the problem. If
there is more than one error, the lamp will identify the first of the problem areas.
