* 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 2.3
· Vertical blanking width should be more than 450
** If the input signal is Generalized Timing Formula (GTF)
compliant, the GTF feature of the monitor will automatically
provide an optimal image for the screen.
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

POWER SAVING FUNCTION
This monitor meets the power-saving guidelines set by VESA,
ENERGY STAR, and NUTEK. If no signal is input to the
monitor from your computer, the monitor will automatically
reduce power consumption as shown below.
When your computer enters power saving mode, the input signal is
cut and NO SIGNAL appears on the screen before the monitor enters
active off mode. After a few seconds, the monitor enters power saving
