shown in Fig. 4.

2. Hold and lift the rear of the chassis and gently pull the chassis toward you, as shown in Fig. 4.

3. Release the respective wiring clips and rotate the chassis vertically through 90°, anti-clockwise.

4. Locate the base of the chassis frame into location (C), shown in Fig. 5. /Fig. 7.

5. Clip the chassis frame onto the bead clamper, shown in Fig. 5. /Fig. 6.

6. After servicing replace the bead clamper, and ensure all wiring is returned to its original position before returning the

ADJUSTMENT PROCEDURE

Item / Preparation Adjustments

+B SET-UP

1. Receive a Greyscale signal.

2. Set the controls :-

Brightness: Minimum

Contrast: Minimum

Volume: Minimum

1. Set the +B voltage up as follows:-

Adjust R811 so that B2 shows 148V ± 1V.

2. Confirm the following voltages.

B9 5 ± 0.25V B10 5 ± 0.25V

B5 12 ± 0.5V B11 33 ± 1.5V

B4 15.5 ± 1V B7 8 ± 0.5V

B12 26 ± 1V B8 5.5 ± 0.5V

B3 39 ± 1.5V B13 13 ± 1V

B1 215 ± 10V B14 -13 ± 1V

CUT OFF / Ug2 Test

1. Receive a Greyscale signal.

2. Degauss the tube externally.

3. Set the TV into Service Mode 1.

4. Select Cut off mode.

To adjust Cutoff connect an oscilloscope to the Blue

cathode. Press "STR" and adjust "cutoff" value using the

"Yellow" and "Blue" buttons until the black level is

160V ± 5V press "STR" to store the value. Remove the

oscilloscope. Select Ug2 adjustment and adjust the screen

VR until the display shows "O.K."

FACTORY SETTINGS

To return customer settings to factory settings and clear owner ID of all information input by the customer, enter Self-Check

mode. Press the down (-/v) button on the customer controls at the front of the TV set, at the same time pressing the STATUS

button on the remote control. To exit Self Check, switch off the TV set at the power button.

If the CCU ports have been checked and found to be incorrect or not located then " - - " will appear in place of "O.K.".

Service Aids

To aid in the service of our current chassis there are a number of Service Aids which have been made available.

•LUCI interface kit (Linked Utility Computer Interface)

Part number: TZS6EZ002

This contains interface and cables for connecting TV service connector and a PC as well as diagnostic software. As new

models are introduced upgrade software will become available.

•VICI (Visual Interactive Computer Information)

These C.D.'s contain multimedia documentation providing quick access to service information.

Part No. TZS7EZ006, TZS7EZ005 & TZS8EZ001

1. Service Manuals

2. Instruction Books

3. Technical Information

•TASMIN (Technically Advanced System for Multimedia Interactive Notes)

As well as providing a first step towards more interactive training this product also achieves quick access to Technical

Information.
