HOW TO MOVE THE CHASSIS INTO SERVICE POSITION
1. Remove the bead clamper from the mains lead and affix, using back cover screw, into top right-hand cabinet rib (A), 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 receiver to the customer. (A)

ADJUSTMENT PROCEDURE
Item / Preparation +B SET-UP
1. 2. Receive a Greyscale signal. Set the controls :Brightness: Contrast: Volume: Minimum Minimum Minimum
Adjustments
1. 2. Set the +B voltage up as follows:Adjust R811 so that B2 shows 148V ± 1V. Confirm the following voltages. B9 5 ± 0.25V B10 5 ± B5 12 ± 0.5V B11 33 ± B4 15.5 ± 1V B7 8 ± B12 26 ± 1V B8 5.5 ± B3 39 ± 1.5V B13 13 ± B1 215 ± 10V B14 -13 ±
0.25V 1.5V 0.5V 0.5V 1V 1V
CUT OFF / Ug2 Test
1. 2. 3. 4. Receive a Greyscale signal. Degauss the tube externally. Set the TV into Service Mode 1. 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. NOTE: Self Check should only be used when refurbishing the TV set and not during normal repair work.
