ENTER SERVICE MODE

1.Select the Pr 91.

2.Adjust “Sparpness “to 0.

3.Enter the service mode using the follow keys.

R G MENU.

2.SCREEN

1)Receive the Retma pattern and heat run over 15minutes.

2)Adjust the “R, G BIAS, R, G DRIVE”to 0, “B BIAS”to 127, “B DRIVE”to 32.

Adjust the screen volume that the Retma pattern reachs the cut-off point.

3.WHITE BALANCE

1)Receive the Full white pattern and heat run over 15minutes.

2)Adjust the picture control at the point “X”value of white balance instrument in 20cd/m

3)Enter the service mode.

4)Adjust “R BIAS, G BIAS”to x=288, y=301.

5)In order to exit the service mode power off the TV set and power on.

6)Set the TV set to “Normal I”mode(20/21 inch) or set to “Normal II”mode(14 inch)

7)Enter the service mode.

8)Adjust “R DRIVE, G DRIVE”to x=288, y=301.

9)Repeat above process until the white balance value to x=288, y=301, X=20, x=288, y=301, X=200

(approximate) in 2) -8).

1.AFT

1)Set a signal Generator with

-RF FREQUENCY = 38.9MHz, 34.2MHz (L’)

-RF OUTPUT LEVEL = 80+/-5dBuV

-System = PAL for 38.9MHz.

SECAM-I for 43.2MHz.

2)Connect the Signal Generator RF Output (PAL 38.9MHz) to P101 (Tuner IF Output). There must be no signal input to the tuner.

3)Locate the cusor to “VCO”in Service Mode Menu, then press the “Vol +”key and wait until the “Please wait”disappear on the TV screen.

4)Connect the Signal Generator RF Output (SECAM-L 34.2MHz) to P101 (Tuner IF Output).

5)Locate the cusor to “VCO-L”in Service Mode Menu, then press the “Vol +”key and wait until the “Please wait”disappear on the TV screen.

4.FOCUS

1)Apply a RETMA PATTERN signal.

2)Adjust the Focus Volume on FBT to obtain optimal resolution.

5.AGC

1)Set a pattern Generator with

-RF LEVEL = 60dBuV

-100% FULL COLOR BAR

2)Connect the Pattern Genetator RF Output to tuner RF input.

3)Connect the probe of oscilloscope in AGC pin of tuner.

4)Adjust the AGC point to MAX - 1V.

( Simple Method )

1)Receive the pattern.

2)Locate the cusor in “AGC”and adjust using the “VOL +”or “VOL -”keys.

3)Adjust the point there is no noise in about 60dBuV and no beat in about 90dBuV.
