Power saving function
This monitor meets the power-saving guidelines set by VESA, 
E
NERGY 
S
TAR, and NUTEK. If the monitor is connected to a 
computer or video graphics board that is DPMS (Display Power 
Management Signaling) compliant, the monitor will automatically 
reduce power consumption in three stages as shown below.
*
“deep sleep” is the power saving mode defined by the Environmental 
Protection Agency.
** When your computer enters the “active off” mode, the input signal is 
cut and NO INPUT SIGNAL appears on the screen. After 20 seconds, 
the monitor enters the power saving mode. 
*** If the horizontal or vertical sync signal is received by the monitor, the 
power indicator may alternately blink green and orange. 
Automatic picture quality 
adjustment function
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 automatic picture quality adjustment function of this 
monitor automatically adjusts the picture position, phase, and 
pitch, and ensures that a clear picture appears on the screen for 
any timing within the monitor’s frequency range (horizontal: 28 – 
64 kHz, vertical: 48 – 75 Hz). 
Consequently, the first time the monitor receives input signals 
that do not match one of the factory preset modes, the monitor 
may take a longer time than normal for displaying the picture on 
the screen. This adjustment data is automatically stored in 
memory so that next time, the monitor will function in the same 
way as when the monitor receives the signals that match one of 
the factory preset modes.
In all modes as above, if the picture is adjusted, the adjustment 
data is stored as a user mode and automatically recalled whenever 
the same input signal is received.
Note
While the automatic picture quality adjustment function is activated, only 
the 1 (power) switch will operate.

SDM-M61
LEAKAGE  TEST
The AC leakage from any exposed metal part to earth ground
and from all exposed metal parts to any exposed metal part hav-
ing a return to chassis, must not exceed 0.5 mA (500
microampers).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or
RCA WT-540A. Follow the manufacturers’ instructions to
use these instruments.
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” indica-
tion is 0.75 V, so analog meters must have an accurate low-
voltage scale. The Simpson 250 and Sanwa SH-63Trd are
examples of a passive VOMs that are suitable. Nearly all
battery operated digital multimeters that have a 2 V AC
range are suitable.  (See Fig. A)
WARNING!!
NEVER TURN ON THE POWER IN A CONDITION IN
WHICH THE DEGAUSS COIL HAS BEEN REMOVED.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY SHADING AND MARK
¡
 ON THE SCHEMATIC DIAGRAMS, EXPLODED
VIEWS AND IN THE PARTS LIST ARE CRITICAL FOR
SAFE OPERATION. REPLACE THESE COMPONENTS
WITH SONY PARTS WHOSE PART NUMBERS AP-
PEAR AS SHOWN IN THIS MANUAL OR IN SUPPLE-
MENTS PUBLISHED BY SONY. CIRCUIT ADJUST-
MENTS THAT ARE CRITICAL FOR SAFE OPERATION
ARE IDENTIFIED IN THIS MANUAL. FOLLOW THESE
PROCEDURES WHENEVER CRITICAL COMPONENTS
ARE REPLACED OR IMPROPER OPERATION IS SUS-
PECTED.
After correcting the original service problem, perform the fol-
lowing safety checks before releasing the set to the customer:
1. Check the area of your repair for unsoldered or poorly-sol-
dered 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.
4. Look for unauthorized replacement parts, particularly tran-
sistors, that were installed during a previous repair. Point
them out to the customer and recommend their replacement.
5. Look for parts which, though functioning, show obvious
signs of deterioration. Point them out to the customer and
recommend their replacement.
6. Check the line cords for cracks and abrasion. Recommend
the replacement of any such line cord to the customer.
7. Check the B+ and HV to see if they are specified values.
Make sure your instruments are accurate; be suspicious of
your HV meter if sets always have low HV.
8. Check the antenna terminals, metal trim, “metallized”
knobs, screws, and all other exposed metal parts for AC
Leakage. Check leakage as described below.
