Notes on chip component replacement

• Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be dam­aged by heat.

Flexible Circuit Board Repairing

• Keep the temperature of the soldering iron around 270 ˚C dur­ing repairing.

• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).

• Be careful not to apply force on the conductor when soldering
or unsoldering.

ELECTRICAL ADJUSTMENTS

Precautions on adjustment:

1. Perform the adjustment in the given order.

2. Power supply voltage: DC 8.4 V

3. Equipment required
Electrical adjustment requires the following measuring equip­ment.

(1) Oscilloscope: 2 phenomena, band 30 MHz or more, with de-

lay mode (use 10 : 1 probe unless otherwise specified)

(2) Pattern generator
(3) Regulated power supply × 2
(4) Digital voltmeter
(5) Frequency counter
(6) Connector for adjustment

4. Measurement points for adjustment are located at CN1003 on
the YC-148 board and at CN206 on the MA-324 board. The
pin No. and signal name of CN1003 and CN206 are listed be­low.

5. Setting up Input Signals
(1) Video Signal

In adjusting this set, video signals obtained from the pattern
generator are used, and therefore these video output signals
must satisfy the specification. Connect the oscilloscope to the
VIDEO IN terminal, and confirm that the sync signal ampli­tude of video signals is approximately 0.3 V, the amplitude of
video part is approximately 0.7 V, burst signal amplitude is
approximately 0.3 V and flat, and the level ratio of burst sig­nal to “red” signal is 0.30 : 0.66.
Where “chroma signal, and color bar signal with burst signal
turned off” is specified in the text, enter chroma signal and
color bar signal of which burst signal is turned off to the VIDEO
IN terminal as video input signals for adjustment.

[Preparation for Adjustment]

1. Service Jigs
(1) Adjusting remote commander (RM-95-modified)

Note 1: J-6082-053-B

(2) Extension cable (for remote commander plug converter)

J-6082-291-A

Note 1: The page will not be changed over, unless the microprocessor in

the adjusting remote commander is a new one (UPD7503-G-C56-

12). In such a case, replace with new microprocessor (8-759­148-35).

2. Adjusting Remote Commander
For the adjustment, the adjustment data saved in the nonvola­tile memory (EEPROM) must be rewritten, and for this pur­pose the adjusting remote commander is used.
The adjusting remote commander makes two-way communi­cation with the product using a remote control signal line
(LANC). The adjusting remote commander transmits pages,
addresses, and data up/down commands to the product. The
product transmits pages, addresses, and data to the adjusting
remote commander.

3. How to Use Adjusting Remote Commander

(1) Connect the adjusting remote commander to the CN501 on

MA-324 board via extension cable (J-6082-291A).

At this time, set the switch of extension cable to OFF

(

(OPEN) position.
Set the [PC] or [VIDEO] mode and turn ON the power on
the set.

(2) Set the HOLD switch on the adjusting remote commander to

the HOLD (SERVICE) position.
If connection is normal, the LCD display on the adjusting
remote commander will be as shown in Fig.3-2.

(4) Select page: 0, address: FF, and set 01 data. Thus, the data

input to page: E or F is enabled.

(5) After the adjustment finished, select page: 0, address: FF, and

set 00 data. Thus, the data change on page E or F is disabled.

(6) After all adjustments finished, turn OFF the main power sup-

ply (8.4 V) once.

4. Precaution on Use of Adjusting Remote Commander
Misoperation of the adjusting remote commander could erase
correct data. T o prev ent this, it is recommended to make a note
of data from page E or F before adjustment, and also to make
a note of new adjustment data each time the adjustment of one
item is finished.

5. Data Processing
Certain adjustment items require the microprocessor data to be read out or the displayed data (hexadecimal numbers) on jigs or
adjusting remote commander to be calculated to get adjustment data. In such a case, convert hexadecimal numbers into decimal
numbers once, then make calculation, and convert its result into he xadecimal n umber as adjustment data. Table 1 shows hexadecimal
– decimal number conversion.
