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.
TIMING SPECIFICATION
SELF DIAGNOSIS FUNCTION
When a failure occurs, the STANDBY/TIMER lamp will ßash 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 Þrst 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:
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
touching 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
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 speciÞed 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.
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 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
instructions.
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 2 VAC range are suitable (see Figure A).

1-1. CABINET REMOVAL
SECTION 1: DISASSEMBLY
Remove (2) Screws (+BVTP 4 x 16)
Release side claw - Insert the tip of a ßathead
screwdriver approximately 0.25" to unlock the
claw.
Release top claw - Working from the same
side as the the claw in step 2, insert the tip of
a ßathead screwdriver to unlock the top claw.
Release top claw - Repeat Step 3 on the
opposite side.
Release side claw - Repeat Step 2 on the
opposite side and gently lift up and then back
to remove the cabinet.
1. When the D-board is placed
in service position, the Safety
Earth Wire (green and yellow
wire) is disconnected.
2. After service is completed and
the D-board reinstalled, the
Safety Earth Wire must be
reattached to the chassis with
the proper screw. This must
be conÞrmed before any
subsequent procedures are
attempted.
1-2. SERVICE POSITION

Prepare a connector (10 Pin: Black) (1-766-921-11), cut of
the boss on the 10 pin side.
Remove the connector (17 Pin: Black) (CN9997), from
Adaptor Board (XT MOUNT) (A-1391-123-A).
Install the connector (10 Pin: Black) onto XT Mount.
Remove the D Board.
Remove the Video Block Assembly.
Install the Adaptor Board (XT MOUNT) (A-1391-123-A).
7 Lay the Video Block Assembly over 90°.
8 Install the Video Block Assembly.
Put a box which is about 15 cm in height under the D Board
to Þx it. (Please disconnect the CN 701 Þrst)
