* Recommended horizontal and vertical timing condition
· Horizontal sync width duty should be more than 4.8% of total
horizontal time or 0.8
µsec, whichever is larger.
· Horizontal blanking width should be more than 2.5
· Vertical blanking width should be more than 450

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 con-
nections. 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 mount-
ing hardware have been replaced. Be absolutely certain that youhave
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 dete-
rioration. Point them out to the customer and recommend their replace-
6. Check the line cords for cracks and abrasion. Recommend the replace-
ment 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
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 ana-
log meters must have an accurate low-voltage scale. The Simpson 250
and Sanwa SH-63Trd are examples of a passive VOMs that are suit-
able. Nearly all battery operated digital multimeters that have a 2 V AC
range are suitable. (See Fig. A)

This monitor meets the power-saving guidelines set by VESA, EN-
ERGY STAR, and NUTEK. If the monitor is connected to a compu-
ter or video graphics board that is DPMS (Display Power Manage-
ment Signaling) compliant, the monitor will automatically reduce
power consumption as shown below.
Power mode Power consumption
55 W (max.)
3 W (max.)
2 W (max.)
*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.
"deep sleep" is the power saving mode defined by the Environ-
mental Protection Agency.
*** If only the horizontal or vertical sync signal is input to the moni-
tor, the power indicator may alternately flash green and orange.
POWER SAVING FUNCTION
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
themonitor's memory to provide a high quality picture at the
centerof the screen.
For input signals that do not match one of the factory
presetmodes, the automatic picture quality adjustment function
of thismonitor automatically adjusts the picture position, phase,
andpitch, and ensures that a clear picture appears on the screen
forany timing within the monitor's frequency range (horizontal:
28 -80 kHz, vertical: 48 - 75 Hz ).
Consequently, the firdt 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 when-
ever the same input signal is received.
While the automatic picture quality adjustment function is acti-
vated, only the (power) switch will operate.
