1.

After replacing the LCD panel

(1) White balance adjustment. (Refer to Section 2-4.)
(2) CLEAR ETI TIME. (Refer to Section 2-3 step 3.)
(3) Check of picture and sound.

2.

After replacing the A board

(1) White balance adjustment. (Refer to Section 2-4.)
(2) EDID writing.
      As the write protection is not applied in this unit, it is possible to write data
      with an ordinary writing fixture.
      It is required to be written for INPUT1: DVI-D, INPUT1: HD15, and
      INPUT2: HD15 respectively.
      Take care that the data for DVI-D and HD15 terminals are different
      from each other.
(3) EDID copy to the EEPROM and ETI clear. (Refer to Section 2-1 step 6.)
      Be sure to perform them after EDID writing. After executing, check
      that the correct model information is displayed. (Refer to Section 2-1 step 1.)
(4) Operation check of buttons and LED's in the front panel, and Check of
      picture and sound for respective inputs.

3.

After replacing the I board

(1) White balance adjustment. (Refer to Section 2-4.)
(2) Check of picture and sound.

4.

After replacing the G board

(1) Operation check of the MAIN POWER switch.
(2) Check of picture and sound.

5.

After replacing the H board

(1) Operation check of buttons and LED's in the front panel.

6.

After replacing the U board

(1) Check of speaker output.
(2) Check of headphone jack output.When connecting a plug to the headphone jack,
      confirm no sound from the speakers.

Circuit diagram division code

•

All capacitors are in µF unless otherwise noted. (pF:  µµF)

Capacitors without voltage indication are all 50 V.

•

Indication of resistance, which does not have one for rating electrical

power, is as follows.

Pitch: 5 mm

Rating electrical power 1/4 W (CHIP : 1/10 W)

• All resistors are in ohms.

•

: nonflammable resistor.

•

: fusible resistor.

•

∆

: internal component.

•

: panel designation, and adjustment for repair.

• All variable and adjustable resistors have characteristic curve B, unless

otherwise noted.

•

: earth-ground.

•

: earth-chassis.

• When replacing the part in below table, be sure to perform the related

adjustment.

• All voltages are in V.

• Readings are taken with a 10 M  digital multimeter.

• Readings are taken with a color-bar signal input.

• Voltage variations may be noted due to normal production tolerances.

•

*

: Can not be measured.

• Circled numbers are waveform references.
