SAFETY CHECK-OUT

DSC-1024HD

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 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 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.

Parts on Set

AC

1.5 k

Ω

Voltmeter
(0.75 V)

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 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!!

Using the line doubler

The line doubler function of this unit converts the input NTSC
or PAL signal into a digitally interpolated, high scan-rate
output signal. The output signal format becomes a non­interlaced signal whose horizontal frequency is 31.5 kHz and
vertical frequency is synchronized to the input signal.
The line doubler up-converts the signal field by field by
interpolating information on two line signals vertically.
Therefore, a fast moving picture is reproduced as a natural
high-resolution picture.

• The converted signal is output from the RGB/component
output connector in the RGB format.

• The line doubler can be activated for the three inputs
separately.

Activating the line doubler

1 Press the OUTPUT FORMAT button to select 31.5k.
2 Connect a NTSC or PAL signal source and select the

input with the INPUT SELECT buttons.

3 Press the LINE DOUBLER button.

The indicator of the button lights, and the NTSC and 31.5k
or the PAL and 31.5k OUT indicators light.

SOFTWARE (COLOR ADJUSTMENTING, ETC.)

3-1. Necessary Items

One 3.5-inch floppy disk (Parts No. 3-702-760-01)
RS-232C cable (Dsub 9/MiniDIN 8) (Parts No. 1-690-391-21)
IBM/PC or compatible (MS-DOS Ver. 5.0 or above)

3-2. Purpose

This service kit can be used for the following adjustments.

1) Color-adjusting the DSC-1024HD

2) Loading the geometry factory setting data of the DSC­1024HD

3) Checking the main CPU operation of the DSC-1024HD

4) Passing digital circuits

These adjustments are used in the following.

1) This adjustment is necessary when a signal gain is changed
due to device replacement, etc. When the color or luminance
of output signal is incorrect, perform this adjustment.

2) In the DSC-1024HD, the geometry factory setting data
which displays an image with correct size and correct posi­tion when a preset signal is input is stored in the EEPROM.
If this data is lost due to the CPU or EEPROM replacement,
load this data.

3) This function displays an operational condition of the CPU
of the DSC-1024HD. This allows the CPU operation to be
detected when the CPU is normal, and parts which need to be
repaired can be located.

4) This function is useful for discriminating failure between the
decoder and encoder analog circuits when the DSC-1024HD
does not operate correctly. However, note that format con­version (timing conversion) is not carried out in input/output
during operation.

3-3. Setting

Connect a RS-232 cable (Dsub 9) to COM1.
Connect the MiniDIN 8 of the RS-232 cable to CN252 of the
unit.

Installing software
The following files are provided in the 3.5-inch floppy disk.
DSC.EXE adjustment program
Preset data for HD10. PRE microcomputer V1.0

on a PC hard disk.

Note: Although the color data of this program is saved in a PC

file, it can be saved only in the directory with DSC.EXE.
The color data or preset data saved in the PC can be read
for transfer to the unit. However, a file used for this proce­dure should be kept in the directory with DSC.EXE.
When performing DSC.EXE, this should be carried out
from the directory with the DSC.EXE.
