POWER MANAGEMENT
The power saving mode complies with the VESA Display Power Management Signaling standard. Each
state of power management shall be activated by the host computer terminating the appropriate sync
signals. Blanking the video must precede termination of the sync signals. The elapsed time counter
shall also be controlled by the host computer. Reactivation of the monitor shall be accomplished from
the host computer by re-establishing the normal sync signal.

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.

SAFETY CHECK-OUT
After correcting the original service problem, perform the
following safety checks before releasing the set to the
customer
following safety checks before releasing the set to the
customer
:
Leakage Test
The AC leakage from any exposed metal part to earth ground
and from all exposed metal parts to any exposed metal part
having a return to chassis, must not exceed 0.5 mA (500
microampere). Leakage current can be measured by any one
of three methods.

1. Check the area of your repair for unsoldered or poorly-
soldered connections. Check the entire board surface
for solder splashes and bridges.

2. Check the interboard wiring to ensure that no wires are
“pinched” or contact high-wattage resistors.
3. Check that all control knobs, shields, covers, ground
straps, and mounting hardware have been replaced.
Be absolutely certain that you have replaced all the
insulators.

2. A battery-operated AC milliammeter. The Data Precision
245 digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of
a VOM or battery-operated AC voltmeter. The "limit"
indication is 0.75 V, so analog meters must have an accurate
low voltage scale. The Simpson's 250 and Sanwa SH-63Trd
are examples of passive VOMs that are suitable. Nearly
all battery operated digital multimeters that have a 2V AC
range are suitable. (See Figure A)
