* Recommended horizontal and vertical timing condition
Horizontal sync width duty should be more than 4.8% of total
horizontal time or 0.8
µs, whichever is larger.
Horizontal blanking width should be more than 2.5
Vertical blanking width should be more than 450
× 1200 resolution signal is acceptable only when it is a
digital RGB signal and its vertical frequency is 60 Hz.
Design and specifications are subject to change without notice.
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 microamperes).
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" indication 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)
After correcting the original service problem, perform the following safety
checks before releasing the set to the customer:
1. Check the area of your repair for unsoldered or poorly-soldered
connections. Check the entire board surface for solder splashes and
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 transistors, 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
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
Fig. A. Using an AC voltmeter to check AC leakage.

POWER SAVING FUNCTION
This monitor meets the power-saving guidelines set by VESA,
ENERGY STAR, 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 enter the power
saving mode. It automatically enters the low power consumption mode when the user sensor detects the absence of a user.
*Figures reflect power consumption when the computer connected to the USB upstream connector on the monitor is turned off.

1 Low power consumption mode (user sensor)
When the user sensor in the monitor detects the absence of a user,
the monitor enters low power consumption mode after about 20
seconds. The icon of user sensor appears and flashes on the screen
before the monitor enters this mode. In low power consumption
mode, the monitor is in a power saving state and shuts off power
to all circuitry (except for that of the sensors) regardless of the
setting of the computer.
The monitor returns to normal operation mode when the presence
of a user is detected by the user sensor.
When the monitor enters the power saving mode (as set according
to the computer's settings), the power saving mode takes
precedence over the low power consumption mode. In this case,
the monitor stays in the power saving mode regardless of the
presence or absence of a user.
To return the monitor to normal operation mode, reset the
computer's power saving mode.
If the user sensor does not seem to function properly, refer to the
instructions on the next page.
2 Power saving mode
DPMS defines the active off state according to the state of the
sync signals supplied from the computer. This monitor's power
consumption is input at approximately 1.3 W or less in this state
if the power saving function is set to ON.
When your computer enters the power saving mode, the input
signal is cut and NO INPUT SIGNAL appears on the screen.
After a few seconds, the monitor enters power saving mode.
* "Deep sleep" is a power saving mode defined by the Environmental
· The power saving function may not work normally depending on the
pattern of supplied sync signals. In such a case, set the power saving
function to OFF.
· When you connect a computer whose power is connected to the USB
upstream connector on the monitor, the monitor will not enter the
power saving mode.
